Ideally you’ll be running at or very near 90 FPS so that motion is smooth and input latency is low. If you drop much below that, SteamVR will (sometimes? supposed to?) cut the FPS in half to 45, and then reproject frames to make it appear smooth. In my experience that doesn’t work worth a shit, so I try to get 90. Theoretically you could lower your refresh rate, and I’ve seen people with other headsets doing just that, but from what I see G2 users can only use 90 or 60 Hz. I tried 60 and it looks…quite bad. So I wouldn’t do that.
This setting is irrelevant. It does nothing in VR mode (much like in game resolution settings).
This also does not matter for VR. If the game mirrors onto the desktop (and most seem to do so), it may affect that.
So far my best IQ / FPS balance for IL-2 has been to use Ultra settings in game and then set HDR and Distant Buildings to off. For my SteamVR settings I have the Global Render Resolution set to 100% (3160x3088) and then set the Per Application Render Resolution for IL-2 to 30% (1732x1692). I’ve only flown around a relatively empty map so far, but it stays around 90 FPS. It looks good, but it’s not super sharp, so I may mess around with increasing the resolution and decreasing other settings in the future.
For the record, I did fix the camera as well. I had to go into non-VR mode, load up a map, un-pause, and then use the Ins / Home / PgUp / Del / End / PgDn buttons to center my view where I wanted, and then press F10 to save that setting. Then pressing NumPad 5 in VR mode should re-center you to that. It’s my understanding that I have to do this with every plane that isn’t centered properly.

Every plane, in every session, every time?
Do you have supersampling on or off in SteamVR settings? Does that setting make things clearer or fuzzier in games?
How would I tell if the reprojection is halved?
No, just once per plane (I haven’t even tried another plane yet so I don’t know how many have messed up default cameras).
If you’re referring to the “Advanced Supersample Filtering” I do have that enabled. That in itself is not supersampling. Supersampling would be the resolution slider. If it’s ever set above what the headset resolution is (in our case, 2160x2160) then SteamVR is supersampling, which means rendering the game at a higher resolution, and then downsampling the resulting frames to the headset resolution. The higher you set this, the sharper the image will be, but obviously the lower the performance. The Advanced Supersampling Filtering option I imagine is just a nicer supersampling filter. I have yet to test whether its impact on IQ or performance is significant.
One key takeaway that they don’t tell you up front is that if you set your global resolution to 113% (default), and then set your per application resolution to 150%, and then set your in game supersampling options (if applicable) to 150%, your supersampling options stack and you wind up with an obscenely high rendering resolution which will completely tank performance on any hardware.
I paid the $4 to buy fpsVR on the Steam store. You can run this with SteamVR and your VR game and it will render a HUD element (you look down to see it usually), and on there it shows you all sorts of performance metrics from FPS, AVG FPS, frame times, reprojection rates, dropped frames, and even controller battery life.

Sorry for another question. Is there supposed to be a single keyboard shortcut in IL-2 to reset your headset calibration? There’s one for Star Wars Squadrons that’s really useful. I want to sit higher in my cockpit for every plane so I can see better. Or is the only option the convoluted thing you posted LOL.
The only option that I’m aware of is the convoluted method I posted. If you go into the control remap menu there is a VR camera reset thing you can bind to a key, but from my experience it doesn’t do what you want it to do. It just re-centers you.
You should be able to use the VR desktop to do all this without taking the headset off.
Are they running on Reverb G2s? Older HMDs are much lower resolution. But even at half res the G2 looks nicer than say the Rift S, and should give similar performance.
But yeah, VR is extremely demanding and you can rarely run anything on high settings without decimating resolution.
Sounds like you should have got an Oculus, which is closer to the ‘Apple’ type VR experience. Still needs some technical expertise, but much smoother. :)
Technically, it needs to render higher to account for lens distortion so the ‘native’ rendering res is a fair bit over 2160x2160 (closer to 3100x3100) so anything lower than that will end up with a downsampled image.
Yeah this is really important, you should always try to keep everything at 100% resolution, and make changes in only one of the various places since they all multiply together.

Do I need the SteamVR beta to get MS Flight Sim to work properly?
I don’t know, but I typically always run the beta regardless.

When you setup your room boundary. Are you supposed to do it from eye level when standing or sitting?
Also, do I want to set SteamVR as an OpenXR runtime (under STeamVR developer settings)?
I don’t think it matters since you’re just marking a line on the floor, and the boundary projects infinitely upwards from that. The image during setup shows it being held at chest height.
For the G2 I’d leave WMR as the OpenXR runtime.

Here are my G2 settings of note, Jeff, if they help. This is on a rig with i9-10900K, 32GB, and RTX 3080.
Here’s my OpenXR Dev Tool setting:
Windows Mixed Reality:
MSFS VR Graphics Settings:
Also, SteamVR: (Doesn’t apply to MSFS)

While everybody is fighting their Gen2 headsets, I just gotta say I enabled hand tracking on the Q2 and it’s . . . handy. When you’re done you logically take the hand controllers off so you can long-press the power button, which then throws up a dialogue you have to get a controller to click to turn off the set. It’s neat to just point your fleshy mitt and pinch to click the button instead.

That is fabulous. Thank you!
Out of interest, why do you disable motion reprojection? I’d keep that on in general use.
And why set resolution in multiple places (XR Kit and SteamVR/MSFS)?
Personal preference but I also disable SteamVR Home, don’t need another home screen getting in the way! :)
You mean short pressing the power button doesn’t do what I think it does?

It causes the scenery to stutter in MSFS. 40-45 fps without MP is a much better experience than stuttery 90 fps with motion projection. Motion reprojection doesn’t work well with flight sims.
And for native VR games, my rig is fast enough to run them at 90+ fps without needing MP.
Well you’re running your HMD at half resolution, so the rig is not really fast enough… ;)
I think it should be on for most people in SteamVR. If you never drop below 90, having it enabled shouldn’t hurt?
There’s a block of settings in the WMR tab inside SteamVR, I think this may default reprojection to ‘disabled’ which is why some people are saying it doesn’t work:
I’m finding IL-2 to be extremely playable with the settings pretty high. The scenery doesn’t look great but the plane models do. I’m also not having trouble centering my view in the cockpit. I’ve got it hot key ed to a button on my joystick and it works even in the menus. I’ll take some screens of my settings tomorrow and post them.
I’ve got MSFS to where I’ve got a reasonably playable balance between graphics and frame rate. It’s fun playing the two Sims. A P-51D is a much different experience than a Cessna 272.
VR is a game changer for flight Sims. I’d be tempted to return my G2 were it not for MSFS and IL-2.
Otherwise I echo most of Penny’s complaints. I haven’t ad much luck with the steam vr interface and I’ve disabled it as much as possible.
It is fantastic for IL-2 and Star Wars Squadrons. I really wouldn’t want to go back to pancake mode for either. The same is true for racing sims as well.
Speaking of Squadrons, I am a huge fan of X-Wing, and a sequel has always been right up at or near the top of my ‘most wanted’ list. I am having quite a lot of fun with this. I’m using my trusty old Sidewinder Precision 2, and it works great apart from the fact that this game wants 20 different buttons. But most of them are superfluous, and I can get by just fine with my 8 + HAT (except sometimes the menu doesn’t want to accept keyboard commands and I have to quit the hard way).
I don’t know how far along I am in the campaign, but I hope they continue to make SP content with this engine. I’d pay good money for an X-Wing / TIE Fighter / XvT / X-Wing: Alliance remaster.

What kind of FPS are you getting? Right now at 100% ss I have to set all settings to low to not even get 80 fps.
