Thanks for the response Qcumber. I really should have asked how much roughly is QVFR faster than FFR from OpenXR toolkit since I already use that (but is it really active with Virtual Desktop - even though I see the appCPU/GPU timings??)

Just how much (percentage) roughly does quad-view foveated rendering improve performance for a Quest3 on a RTX3080ti running godlike resolution?

Try running at 72Hz ( 36 FPS ) and using Virtual Desktop (Godlike mode 3000x3000 res) using a Wifi5 AX ($50) or wifi6e AXE second router ($150) setup as an Access Point (reserved static IP, DNS) connected by 1Gbps cable to first router which is connected to PC with 1Gbps cable. See Virtual Desktop Discord for example routers DCS Settings: VR Tab Pixel Density 1.2->1.3 and enable HMD mask System: Res of Cockpit Displays: 1024 , Antialiasing off, Upscaling: Off, Shadows: Flat Only Flat Shadows Blur: Off, Civ Traffic: Off, Water: Low Lower Forest and Scenery Detail, Rain Droplets: disabled OpenXR Toolkit : Some FSR or NIS or CAS

Color-panel as mentioned just above works very well (BUT JUST FOR MSFS) - just set the passthrough color in Virtual Desktop (Streaming at the bottom center ) to purple with a small amount of threshhold in VD. Then when you are flying in VR mode, the Toolbar will then have a tab just to the left of center to enable it. Then you just move the panel to where you want it and size it. When you click on it to minimize it so you can see on the other side of it, it leaves a small outline and a small circle in the center of the passthrough panel to reenable it. I found that if I selected the panel by holding down the left mouse button, I could "bring" the panel toward me which helped my eye distance focus. I asked in the review comments if the addon author could make it work for DCS but no answer yet

How do you set this up?

NonVR - Tried removing (after backup though) SavedGames/DCS and checked ST/MT - no significant difference with simple test like stock P-51 at Batumi parking. 9700K@5Ghz, RTX3080ti With VR (Quest2+Airlink), I did see very decent reductions in appCPU times (from 11 to 5 ms or so), however, many more stutters than nonMT.

I didn't see you mention loading OpenComposite dlls and replacing openvr_api.dll - do some Google searching.

I just tried the most recent Virtual Desktop - still get more clarity on Airlink (200Mbps) and unfortunately, I get more head lateral movement stutters with VD.

I've tried TrackIR, OpenTrack with AITracker and quite a few other combinations to get a reliable, non-noisy way to look sideways on a 2D monitor and I just recently tried the Neuralnet tracker option with an inexpensive $25 Logitech Windows 11 720p webcam in daytime and with medium-level nightime lighting. I found it to be really useable and I can fly turns around a point on the ground well. It also lets me lean forward to naturally "zoom" in on the instrument panel. I had to use the mapping option to double/triple default yaw movement while lowering (half, third) x,y,and z movements. You have to use a key to center the movement before the z axis (fore/aft) will work. I appreciate that I don't have to use flat spots in the curve mappings to get "locked-in" viewpoints.

The big issue with Win11 and Quest2 right now is increased stuttering. The fixes that I have seen are using ODT to toggle the console window to being visible constantly or another fix that involves setting the audio merge from the Quest and from the computer (search for this one). Using this fix, flight sims are much smoother and ASW works well.

I have a 9700K@5Ghz and a RTX2070 (not Super) v33 or v34 for both Oculus Tool and Quest 2 Q2 90Hz at max 5408x2736 ODT / OTT (I use both) Pixels per Display Pixel Override (Default Super Sampling) = 1.1 OTT - ASW 30Hz - some folks prefer OFF FOV (.8;.8 ) Note: Use in DCS Ctrl+Pause to show FPS (upper left hand corner ) and confirm 30 (try 45 as well ) - I like a non stutter result out the side window ODT - Oculus Link Low, 2912,Disabled,0,300,0,Enabled Make sure you test your Link cable to being greater than 1 Gbps (mine is 2.6 for a $30 cheap USB-A to USB-C )

OK - I forgot to change the settings on the Launcher so that Oculus was the default. I will have to test the performance differences though - for curiosity - I did notice that I could easily have the Oculus Performance HUD show with SteamVR but not with direct Oculus - unless I am missing something. Anyway, 30Hz is very smooth and the Link sharpening is a big improvement.

Possibly this level of performance / smoothness (no stutter when looking sideways) plus image clarity was possible before but I didn't realize that I could set the ASW "lock FPS" value to 30 Hz (using Oculus Tray Tool) even though I have to use SteamVR with the Oculus Quest2. My PC is a 9700K@5Ghz+RTX2070 and it seems to look really good at ASW on/30Hz along with the recent image upgrade called Link sharpening. My non ASW performance is just below 45Hz so 30 Hz is rock solid even with MSAA 4x. I know that motion reprojection has its downside but I just prefer to be able to look 90 degrees from boresight and have it be smooth like in RL.

I had the black screen after Launch for 30 seconds then return to Q2 only problem as well. It seemed to be fixed when v29 of the Oculus PC runtimes app got auto updated - try again when you see the update. Airlink with ODT setting of ASW forced enable gave me a very steady, fluid flight at 36fps (1/2 of 72Hz).

Colonel_Izzi on reddit says: When running SteamVR apps on Quest2+(Air)Link, the Oculus PC runtime still handles the final stages in the rendering pipeline, where ASW,FOV-Tangent Multiplier, ASW, etc can be performed
