VR Stream Testing

The other day I wanted to have some fun, so I loaded up the Colimata FA-18 in X-Plane VR and flew around the Salt Lake City area some. Performance under X-Plane 1.5beta3 in the sim was very, very smooth, yet I noticed that on the YouTube stream there were all kinds of stutters and judders. Yesterday after work I made another flight (video below) with the intention of testing different settings to see if they made a difference on the YouTube side. I’m sorry to say that the stutters and judders in the YouTube playback are still there. I’ll continue to explore the issue

, but it really does ruin the video in my opinion.

That said, flying around the canyons and mountains of Utah in VR at 500 knots is still a ton of fun …

The PilotEdge I-1 Rating In VR (X-Plane 11.3b5)

One of the fantastic things about PilotEdge is the significant amount of educational resources they provide, one of which is the “I-Rating” series of training scenarios. I’ve already passed the I-1 rating on PilotEdge but thought it would be fun to fly it in VR (it’s an IFR flight to and from John Wayne using the ILS 20R approach) in IFR conditions. I bring Navigraph maps (I picked up an annual Navigraph subscription this week) into the virtual cockpit via the AviTab plugin, which works well. X-Plane 11.3beta5 eats 11+ gig of my VRAM for some reason, which does not work out well. But we complete the flight nonetheless.

Three thoughts based on this simulated hop: 1) Gotta figure out the VRAM situation, as that’s not good and it’s never happened to me before in X-Plane. 2) IFR in VR was very realistic, especially with the clouds. The Jeppesen charts in the cockpit via AviTab work great

, but it’s still quite taxing to manage radios and notes under the headset. This may be a good thing, though, as it creates task saturation, and the realism of VR may make it worth it as it really felt like being under “the hood” real-world. 3) I’m going to plow ahead with the I-Ratings (I’ve done them through I-4 but will do them all starting with the I-1) and their supporting videos as a jump-start on my real-world instrument training. I’ll fly some in VR and some in the physical cockpit and decide which feels like better training and report back.

Home Cockpit / VR Video Compare & Contrast

As I’ve been working more in VR alongside the home cockpit, I’ve been trying to video / stream of both. Each has its supporters, although on the whole my sense is that the YouTube audience prefers the home cockpit over the VR. I think that’s right. It’s a better visual experience (and not as potentially nauseating!), and probably feels more “real” to the online viewer. Chas

, who comments here often, is trying to get me to stream in 3D so others could use their own VR gear to truly see what I see, but I’ve not gotten there as yet.

So I thought it would be interesting to post two recent streams here side-by-side. One is VR, the other home cockpit. I completed the home cockpit flight later today. It was fun, and it was certainly faster to work the GPS and the radios than in VR, and it was nice looking at a real iPad and ForeFlight display. But I have to tell you – it didn’t feel as much like flying. My plan is to probably stream in the home cockpit, but I’ll probably use the VR more often when flying on my own.

 

“Which Do You Prefer, VR Or Your Home Cockpit?”

I’m getting this question a lot, and a viewer seems to ask it in every live stream. So I thought I’d post a bit about how I consider the question, and why my answer is not as straight forward as some might expect.

Right now, I would say that I prefer VR, but that’s not a consistent preference. It does change based on the situation. But I’ve noticed that as I go into the sim closet for a flight I’m more inclined to reach for the goggles instead of the remote for the projector. So let me get into some of the factors that matter for me, and I’ll contrast the physical and virtual cockpit experience in each. Note that I have an Oculus Rift, so I can’t speak to other HMD devices, and that I fly in X-Plane using native VR support.

Comfort

The home cockpit has an edge here. But it’s not about the goggles. I actually find the goggles very comfortable and don’t mind wearing them at all. It’s more about the overall comfort of being able to see your environment, put things places and see where they are, and the overall sense of physical freedom that comes with being able to see your surroundings. While I find the goggles comfortable, it’s nice not to have to peek under them, lift them up, etc. when I need to change a setting or grab a pencil. This isn’t a huge deal, but it is part of the experience.

Price

An easy win for VR. I picked up my Rift, which came with two sensors and two hand controllers, over a holiday sale on Amazon for $399 and I see it is still available at that price. The price for the home cockpit: no man can say! At least, no man should add it up if he doesn’t want to feel wasteful. For the quality of the experience, VR is in my view a significantly more cost-effective way to have a very immersive simulation experience, presuming you have a system powerful enough to run it. But that’s a wash, as you need a very powerful system to run three or four screens and a ton of devices in a physical cockpit, too.

Simplicity Of Environment Setup

The Rift is the clear winner here. Getting a physical cockpit up-and-running is never a straight-forward task, although it provides a dimension to the hobby that many, including me, can enjoy thanks to its high geek factor. But the fact is that even the most basic home cockpit requires a fiddling with USB ports, hubs, drivers, power management settings, etc. that VR just does not require – and that an operating system update nearly always requires you to repeat in some manner. And this is before you get into the nuances of having your gear communicate easily with your sim, which adds a whole new layer of driver and software support.

With the Rift I plugged the headset in, plugged in the two trackers, placed them in locations for good tracking, ran the Rift setup software, and was done. After that, and after learning the best practice for good performance on my rig which I detail in a post here, I made changes to the power management and overclock settings of my BIOS, PC, and GPU; changes to the SteamVR / Rift settings; and changes to the performance settings of some applications via Project Lasso. These were one-time changes, and candidly, they helped improve the performance of the physical cockpit as well.

With VR you also don’t need to build a cabin. That was a fun part of the experience for me, but it was an awful lot of labor (be it a labor of love).

Simplicity Of Sim Setup

A big nod to the Rift. As those who have built cockpits like mine know, it takes quite a while to get your aircraft and views set so everything looks just right, and in particular, so the front and side views appear in alignment and proportion. While I have posted how-tos on this (for P3D and XP) that helps people save some time, it still takes quite a bit of tweaking. In addition, in XP one needs to modify the aircraft models in PlaneMaker so that one doesn’t see unwanted parts of the cabin, and this also takes some tweaking. With the Rift you just launch a flight and go, although I do move my eyepoint around just a bit so that my yoke is where it should be given the virtual cockpit perspective. That takes just a few seconds, and I could modify the aircraft file’s eyepoint to make that setting permanent if I wished (but it’s so easy to do that I have not bothered).

The Rift also wins for device configuration, as I don’t need to set up specific device profiles for the TPM etc. based on the controls of different aircraft I might fly. I just use the Rift controllers to manipulate whatever needs manipulating in the virtual cockpit.

Simplicity Of Startup

The Rift wins here, but it’s close. On startup in the cockpit I need to turn on all the monitors and projector, overclock the GPU, launch (and have run correctly) SPAD.neXt, RF Cockpit, and the program that lets the radios talk to the sim, then launch X-Plane. I have a variety of devices that make the home cockpit as realistic as it is, so for me this is more complicated than it would be for some. For the Rift I turn on the PC and its main monitor, overclock the GPU, open Oculus Debug Tool and set AWS to fixed at 45FPS, and launch X-Plane.

Graphics

I am going to call this a qualified tie. In terms of visual quality, the traditional cockpit wins. Sitting next to a 1080p screen (or higher) provides a very sharp image. BUT – my projector view is not nearly as sharp, and while it is 1080p I can see the pixels because of the image size, so it already has a subtle screen-door effect. While you can’t see this on my videos, you can in person. But with SuperSampling set to 1.6 or 1.7, the image in the Rift, to me, looks really good, and it is very difficult to describe the quality that 3D brings to the visual experience. I strongly prefer it to 2D even with its lower visual quality.

Performance

In what may be a surprise to some, I’m going to give the nod to the Rift here. But your mileage may vary significantly, and there are situational variations. And as we get into this, note that I have a 908ti GPU and a i6700 CPU running at about 4.6, so hardware matters here. On my rig, even with all the tweaks I’ve made, in the physical cockpit I still frequently find micro-stutters, and in SoCal, low framerates unless I back of my settings some. I try to average 30 FPS, and X-Plane looks great at 30, but in congested areas it’s obviously lower and in the back country it’s closer to 50. Clouds don’t affect it much, although in IMC I need to back of my AA settings in the physical cockpit or things get slow quite quickly.

When I first used the Rift, my performance was horrible. Unflyable for me. Stutters, judders, low frames. I was ready to take it back. But as I learned more about settings and made the changes I’ve pointed to earlier, I now actually prefer the performance I get in the rift. In the rift I have the same objects and texture settings that I do in the physical cockpit. I run at HDR, as I do in the physical cockpit. I use a lower AA setting, but it looks great thanks to SuperSampling. And because I have it locked at 45 FPS, the resulting performance is extremely smooth. No micro-stutters and a very fluid experience. In SoCal it gets worse, so I turn down the objects settings a notch. But I do this in the physical cockpit as well. So all in all, I actually prefer the Rift, which is a big departure from where I started.

Kinesthetics

I call this a tie. “Feel” is a big deal in the real vs. VR debate. And when VR first came on the scene, I shook my head and said, “You can never replace the feeling of flipping a real switch or turning a real dial.” But this was before I appreciated what it was like to use the Rift’s controllers. The way they sit in your hand, the placement of the triggers, and the haptic feedback they provide makes turning a dial in the virtual cockpit feel very much like turning a real dial – or in the very least, it feels like you are turning or flipping something, and not just air. I didn’t appreciate this until I’d used them, and for me it makes a huge positive difference in the experience. And note that even in VR I am still using a physical yoke, pedals, and throttle quadrant, and I would say that all are essential to getting a more realistic VR experience. If I didn’t have them and was getting into VR, I would buy them (and probably a trim wheel, too).

But there is another place where feel matters, and that’s the feel of flying in a real airplane. And for me, VR wins here hands down because of the nearly full field of view and the 3D image. In two years of flying in the physical cockpit only once did I get a sense of spatial disorientation. In the Rift I had it on the first flight, and on nearly every flight when I hit the brakes and the airplane pitches forward, I physically pitch forward with it. The sense of space and motion is so real that my wife can’t even wear the goggles or she gets sea sick. Now, I also use a Buttkicker to increase the sense of feel in my simulator (and in VR), but let’s be honest – it will always be difficult to get the feel of flying without a 6DOF platform on your sim, and even then it won’t be the same. But the Rift gives a very real sense of motion that is about as good as I could imagine without actually moving or feeling the G-forces, and it’s a big improvement to the experience over the physical cockpit with 2D images on the screens.

Simulation Variety

An easy win for the Rift. I intentionally designed my home cockpit to be able to simulate a variety of GA aircraft (even though it’s built to closely replicate a Cessna 182). This is why I use an iPad for the six pack and FIPs elsewhere, and they can display many different gauges and glass instruments. But it strains reality sooner rather than later. It won’t, for example, do any sort of a good job replicating a 737 or F-18. It’s here that VR shines. And I’ll tell you, the first time you sit in the left seat of a VR MD-80, start flipping switches, and rotate for take off? That will blow your mind and bring a huge smile to your face. With the Rift I can simulate a huge variety of aircraft. Not all are VR ready, but that’s only a matter of time (and a short time at that). It’s fantastic.

Immersion

Rift, hands down. I love my physical cockpit and have gone to lengths to make it look and feel realistic (down to the sunshades). But it’s awfully easy to remember I’m sitting in my closet, and the 2D imagery on the screens and the little differences between them as good as my alignment may be are constant subconscious reminders that this is not real. I find the VR experience significantly more immersive, and I actually quickly forget that I’m in my home when flying VR. (Indeed, when you take the googles off, there’s always a bit of, “Oh wow, I’m in my house.”) Many things make it so: the 3D imagery, the 3D sound.

But more so it’s the overall environment, and in particular, the light and how it acts in VR. In the headset light comes through the cabin, reflects off the surfaces, and moves through the overall world in a much more realistic manner than in the physical cockpit. No matter how good my screens, a flood light on the ramp to my right simply is not going to be bright enough to light up the entire cockpit. In VR it’s completely believable. It’s really amazing. I was never quite sure what people meant when they said VR was so “immersive,” but now with time in the Rift I believe it’s the combination of 3D imagery and the way light plays out in the scene. It’s something else. Think of it this way: when I have someone in the physical cockpit with me, they think it’s amazing and often they say, “This is so cool!” When I then put the Rift on them and have them take a few turns in the virtual aircraft, the immediately say, “Oh … WOW.” And then they’re just sort of silent and amazed for a while.

Sharing The Experience

A win for the physical cockpit. What’s more fun that having someone fly along with you? This is why I put dual control in my cockpit and it’s a big part of the appeal – especially when you can have someone sit in a sim for their first time. It’s just a lot of fun to share this experience with friends and family. And while the simulation community is hard at work finding the best way for people to fly pilot / first officer in VR, we’re not there yet, and modern GPUs simply are not powerful enough to run dual HMDs. And besides, what’s the point of sitting next to each other if you can’t look at each other?

Charts, Notes, And Kneeboards

“What about charts and things you need to write down?” is a question I often get. The physical cockpit wins here, but VR is serviceable. I can peek under the headset and see and use my kneeboard relatively easily, and now thanks to Oculus Dash and the ability to mirror my iPad to my PC, I can have ForeFlight in the virtual cabin with me. But it’s not as easy as having the iPad on the yoke and seeing my full kneeboard with a glance, that’s for sure. It’s workable, but not excellent. I do find, though, that it adds a layer of task saturation to the experience, which I think is good for me as a pilot rather than bad.

Training Utility

Here VR wins the sprint, but I don’t know if it will win the marathon. What I mean by this: as a student pilot just about to take my Private check ride, it was clear to me after just a few flights that the VR is a far better training device for me than is the home cockpit. This might surprise some folks, and it surprised me too, but here’s why. First, the sense of space and motion afforded by the VR’s 3D imagery is significantly more life-like than that provided by the 2D images and environmental lighting of the physical cockpit. The pattern looks more realistic, the sense of size and perspective is spot on, and I find the sense of motion for the aircraft (especially on final) much more true to life in VR. And VR flight at night? A black hole looks like a black hole. It’s remarkable. If I want to practice maneuvers or landings, I want to do it in VR.

In addition, in VR I can simulate the exact aircraft I fly in real-life: a Piper Archer II. While the sim version doesn’t have the GNS 430 that I do in the real aircraft, everything else is just where it should be. This means that not only are my visual references for the scan correct, but my flow for my checklists is correct. Practice makes permanent, and when I would spend a lot of time in the home cockpit and then get in the real airplane, I’d always have to remind myself where things were, which is not a good habit to build. This impression is strong enough that when I took a real-world flight last week and a day after having done a two-hour thirty minute flight in VR, I sat down in the real bird and thought, “Oh, back again.” I even wondered why the clock was INOP when it had been working the day before … and then remembered that it was the VR clock I was thinking of. That doesn’t happen with the physical cockpit.

Finally, I’ve found cross-country work in the VR to also be excellent training, especially with ortho scenery underneath. Things look good in the physical cockpit, but in VR the ability to see the scenery, identify landmarks, and look around the aircraft is just much more realistic.

So why is VR in question for the marathon if it wins the sprint? Because I don’t yet know how good it will be for IFR training and its heavy dependency upon chart work. My suspicion is it will be better from a spatial disorientation standpoint, but worse for procedures. It will be a pain just to write down a clearance, I suspect (peek under the headset to write down the CRAFT). As the ability to bring references into the virtual cabin (as I do already with Oculus Dash and ForeFlight) improves this may well change. But I won’t really know until I start IFR training. In the meantime, I plan to try a few PilotEdge I-Rating flights in VR and see how it goes, and I’ll report back when I do.

Gestalt & Summary

So all this being said, where does it leave me? If we consider the whole as being more than the sum of its parts, I prefer VR in combination with a physical yoke, pedals, throttle, and Oculus controllers as a training aid (at least so far for VFR training), as a more realistic overall experience, and simply as more fun when flying alone. It’s also faster to get up and running and has far fewer things I might need to tweak or fix along the way. It’s easier. I prefer the physical cockpit for flying with a friend, and for a complex flight that’s going to require a lot of note taking and chart work. It’s also nice sometimes not to fly with the nerd goggles (as my wife calls them) on my head.

But all-in-all, most of the time when I go into the sim closet, I’m reaching for the VR goggles. I’m surprised by this, especially since I so strongly rolled my eyes and shook my head when people started telling me how great VR was in flight simulation. “No way can it be realistic or a good training tool when you aren’t touching the real radios,” I said. But I now will say I was wrong about that thanks to the Oculus controllers. I think the VR experience is more real than the physical cockpit

, not less.

In conclusion, if starting from scratch and my goal was to have the most immersive, most flexible, flight simulation experience, or if cost was a significant factor, I’d go with VR in combination with a good yoke (I love my Yoko), a set of pedals, a trim wheel, and maybe a throttle quadrant (although the VR throttles are quite good). If my goal was to share a project with my child or children, introduce others to flight simulation, do something at a very high geek level, or train for IFR (although this will certainly be an evolving part of the picture), I’d build a cockpit (and do so at a greater expense).

The VR thing is real, it’s impressive, and it’s here to stay. If you can try it, you should. You might just find it transforms how you think about your hobby.

We Live In Amazing Times: The Latest Live Stream

Tonight I was able to stream XP 11 directly from the Oculus VR headset

kupbezrecepty.com

, on PilotEdge, while monitoring the YouTube live-stream chat in-cockpit via the Oculus Dash feature. Amazing.

We also toss in a few practice engine-out approaches just for good measure.

Our First Video From Inside The Oculus Rift

I finally figured out how to capture Rift video using the Oculus Mirror tool and my NVIDIA Experience ShadowPlay feature (it’s actually quite easy, but it did take some research to figure it all out). I also shot some iPhone video up front so folks could see how I have the sensors set in my cabin, and I do two laps at night, one with HDR off and one with HDR on so you can see the difference.

VR settings:

  • SS and AWS / Autoprojection OFF in SteamVR
  • Supersampling 1.5 in Oculus Debug
  • AWS fixed 45 FPS in Oculus Debug
  • Visual effects 4/5
  • Autogen 4/5
  • AA 2/5 No shadows, no reflections
  • 3jFPS plugin set to 46 FPS

These reflect a change from my prior settings. I found that Oculus Debug Tool does a great job of locking the frames at 45 FPS

, and this makes both the sim scenery and the Oculus movement very very smooth, especially if I have HDR turned off. As some have noted over in the Facebook VAG group the Debug Tool’s FPS lock doesn’t always seem to “take” when you first turn it on. It may have to do with having the Oculus software running first and launching from within it, but I’m not certain. Regardless, I now have the SteamVR improvement turned off in favor of those in Oculus and I like the results.

I had fun shooting this, and I think it illustrates the quality of the experience in VR. One thing you absolutely cannot appreciate from this, though, is the experience in 3D. I’ll post more on this later, and thanks for watching.

 

An Interesting Flight: Oculus, At Night, On PilotEdge

Last night I did my first PilotEdge flight using the Oculus. I loaded the sim at Oceano, which had several people online on the ramp and one flying the pattern, with the intention of doing a few laps of the pattern and then heading north over the hills for a lap or two at San Louis Obispo. Real-world weather (scattered 9,000) and time (night). The aircraft was a Piper Cherokee (can’t remember whose, but it has a 3D cockpit that works relatively well in VR).

This flight was interesting, for a variety of reasons. First, the headphones on the Rift come off easily with a few turns of their screw. I took them off and used my real-world aviation headset over the Rift, and that worked fine. As far as the VR experience, frames were silky smooth with no judders using the settings I’ve posted, with the exception of a few long lags where the sim was clearly dealing with data. My instinct is that I have more of these with HDR on than off, but I don’t really know. There were probably four or five of them in the course of an hour flight, and after maybe a five or 10 second delay things resumed without any difficulty.

Regarding PilotEdge, it worked as expected. I also used my real-world kneeboard to see how it would work, and was easily able to peek under my headset at it for frequencies I’d written down and at my phone (which was running ForeFlight). As for running the radios, the Cherokee I was flying has radios that work in VR but they aren’t optimized (you don’t turn the dial with your wrist like you do in the default 172). They worked fine, but I actually powered up my FlightIllusion radio stack and used it for the radios just by feel, and it worked fine (same for the Saitek trim wheel, which is just easier to use for me rather than reaching down between my seats with the VR controller). The key thing, though, is that VR combined with PilotEdge made for an extremely realistic flight experience. Being able to easily look around the ramp and spot other aircraft moving about, and in particular, being able to see other aircraft in the pattern in 3D and hear them on the radios, was remarkably lifelike.

So, too, was the VR experience of flight at night. The darkness of the horizon, my ability to reach up to the ceiling of the virtual cabin and turn the Cherokee’s red night light up or down and have it illuminate (or not) the entire scene, the shadows and light cast into the cabin by lights on the tarmac or passing buildings on final, the darkness of the area surrounding the strip with only its runway lights sitting in a black hole, and then my landing light illuminating the landscape on final — all of this was far more immersive in VR than it is in my physical cockpit. (One comment here: the modified lights.txt file that I’ve been using is too bright in the VR headset, so I went back to the default.)

Same too for the sense of perspective and space. Looking at the field when turning crosswind to downwind, seeing KSBP coming up in the distance on final, checking my distance to the field on downwind – this was all extremely true to life in the VR, even at night. (Perhaps more so as you can’t see any textures.) I didn’t really need to check the map to see when I was at two mile final into KSBP as I could tell for myself based on my real-life flight experience. The motion of the airplane on takeoff and final was also more immersive in 3D VR. On final in particular I “felt” the little movements of the airplane up and down and side to side much more so than in the physical sim cockpit, especially with the crosswind I had going. These landings were much more like real landings to me.

So all of this was really very striking. Craning my head behind me and seeing the 172 also in the pattern at Oceano, whom I had just heard make his downwind call on PilotEdge, with his landing light illuminated. Seeing that same 172 on its departure leg, with its beacon and strobes flashing in the darkness just as would in real-life, not too bright nor too dark, as I flew downwind. The shifting illumination of the cabin. The real-world ATC and radios. The movement of the simulated aircraft through space. I left the experience thinking that, for me, that 3D VR flight combined with a physical yoke, pedals, and trim wheel (and perhaps throttle, although the VR throttle works great), was absolutely a better night-pattern simulation (and for me, training exercise) than I would have gotten from the 2D world brought to life in my physical sim cockpit. If I wanted to work on my night pattern work, I’d reach for the VR headset for sure over booting my real cockpit. And the use of maps, kneeboard, and radios was not nearly as clunky as I thought it would be. A quick peek down my nose or a quick lift of the headset was all it took, and as the tech for brining apps into the VR cabin improves, this too will get easier. (And a quick note to Laminar here: please make it so we can click on a VOR or field in the X-Pad map and get its radio or runway information. You can do this in the non-VR map, and it would make things much easier in the VR cabin.)

It will be interesting to see how long I go before flying in the physical cockpit again. VR has its issues for me. Too much time with the headset on makes my eyes a bit wonky, for one. I can’t fly with a co-pilot, for another. I expect that IFR work (with its charts) would be harder, for a third. But I rarely take long, co-pilot, or IFR flights. And for me, VR with traffic and real radio work over ortho scenery was an amazingly realistic experience. I can’t wait to do it again, and if you have the PC and GPU horsepower and are passionate about flight simulation, I think you really do need to give VR a look.

The Rift Is Dialed In

After continued testing and trial, I’ve found settings that work very well for me in the Oculus Rift, with smooth movement and no judders. Sitting at Albert Whitted near Tampa I was getting 90-100 FPS before activating VR and 45+ with it at the default KSPG airport, and 60-70/45 with the custom KSPG (which is much more taxing). Weather was set to real world, with some clouds in the area. The 45 FPS held as I flew around the Tampa area, held when I turned on WorldTraffic 3.0, and held when I went from non-HDR to HDR lighting effects. I did have more pauses and stutters after moving to HDR, though, so I will fly with it at night only. Without WT3 I don’t know that I would have had these, and I also realized my custom KTPA was loading on top of the Tampa scenery package KTPA, so the sim was managing two large airports on top of each other. But the flying was great, and I’ll be using these settings going forward. And it was really great to experience a big airport with traffic moving around in VR.

After reading a number of posts online at the Facebook Virtual Aviation Group, I decided to run without the Oculus app running (set the Occulus app to “Run As Administrator” and it will stop loading whenever the Rift is active) and without OTT or the Oculus Debug too, and instead only use SteamVR. I figure the fewer the software layers involved the better. Here are my settings (and remember I’m running an i7 6700 clocked to about 4.6 and a 980TI also overclocked just a bit):

  • In SteamVR:
    • Developer Tab: Supersampling set to 2.0 and Advanced Supersampling Filtering ticked ON (I picked 2.0 on a lark, and don’t know how high I can go with this yet)
    • Performance Tab: Allow asynchronous reprojection and Allow interleaved reprojection ticked ON (this was important – when I turned these off I had judders galore)
  • In the X-Plane Graphics Tab:
    • Main monitor set to 1280×720 – I figured by downscaling the main monitor I’m saving processing power for the VR headset (this may or may not be the case, but I’m happy with the results)
    • Visual Effects set to middle setting (one below HDR)
    • Texture Quality set to Maximum (one below highest setting)
    • Antialiasing off (I didn’t miss it with the supersampling, although adding AA didn’t hit frames that much; when I turned on HDR visual effects I set AA to off)
    • World Objects set to High (one below max)
    • Reflection Detail at lowest setting
    • Draw Shadows On Scenery set to off
  • In the 3jFPS plugin (a must-have, in my opinion) I ran the wizard and set it to keep frames at 50, which I figure will keep me at or above 45 FPS most of the time. I still had a world full of objects even with the plugin running.

Ironically, those settings are quite close to what I ran with in non-VR. But the important thing was that I was getting 100 FPS sitting at the default Albert Whitted, and I do believe setting the main monitor to 720p had something to do with that. The only downside was that it moved all my icons around on my desktop! Next step is to try the VR on PilotEdge …

Oculus Fourth Impressions

Today I did two things with the Rift: flew in DCS (Digital Combat Simulator), and flew in a Piper Warrior II (my old trainer) from my old home strip (KOQN) in X-Plane 11. Thoughts on each …

DCS was great. Easy setup and ran right out of the box. I only have the default aircraft and areas, and nothing in the default fighter is clickable, but the headset and controllers worked fine. Graphics were great with no stutters or juddering. The effect is jaw-dropping, and I felt a little shudder of spatial disorientation more than once. Looking around the cockpit is an incredible experience, and I can’t wait to get more into DCS in the coming weeks. Expect more posts about that here soon.

But while the DCS flights were fun, it was the pattern work in the VR headset at my old strip, in a Warrior II with a 3D cockpit like the one I used to fly there, that was most interesting. I flew three laps of the pattern. All I can say is that it was almost just like the real thing, and a MUCH more realistic experience than flying those patterns in the real basement sim cockpit. Why was this? First was still being able to use a physical yoke and pedals. For me being able to physically “hold onto the airplane” is important to the realism of the flight. Second was having the VR cockpit panel and controls very well aligned to the physical yoke (using the process I described in this post), which meant the visual matched the expected physical quite well. Third was having a quality, 3D, clickable cockpit of the same airplane I used to fly. I could look down and pull up the virtual flaps handle, just like I used to. In fact, the virtual cabin was so good that I used the virtual throttle rather than my real one.

But most important was the sense of space, distance, and perspective that the 3D virtual environment affords. Very often in my physical cabin I would look out the left or right-hand window (right for KOQN as it’s right traffic) and the field just would not look the same as in the real world – it would not look as high, or have quite the right perspective. While the pattern is still much easier to fly in the “one front, two sides” monitor configuration I have in the sim, it never quite looked the same as real-world. I couldn’t really put my finger on this before, but now having flown in VR the same pattern that I flew so many times in real life, it’s absolutely obvious to me. For all intents and purposes, flying the pattern in VR was almost exactly like it was in the real world – the only exception being that the Warrior in the sim climbs a bit quicker than the real one, and I flew the pattern a bit faster than in the real world (abeam the numbers came up a bit faster than it seemed to in the real bird). But especially with orthophotos underneath, flying that pattern was almost just as I remembered it, as was the landing.

Based on that experience I have come to a pretty interesting conclusion – for pattern work, and probably maneuvers as well, I think the VR headset with a physical yoke and pedals probably provides a better simulated training experience than the physical cabin. I know, and I can’t quite believe I’m writing that. Now let’s be clear – I’m not anywhere near ready to sell the cockpit, and I’m going to fly the VR on PilotEdge later today to see how workable the radios really are. But those laps of the pattern in the headset really struck me. It was so much like the real thing, with a cabin and panels like the real thing, and scenery based on the real thing, and performance close to the real thing, that for me I have to believe it would be better virtual practice for pattern work and maneuvers (at least) than the basement sim. It may be for emergency procedures as well, and I’ll run some to see how it feels (although there will be no checklists to hold, at least not so far). We’ll see how things continue over the next couple of days, but it has me shaking my head yet again.
