Sorry for not posting the OTT Quest Link info: just Low, 2912,300 (or 0), Enabled and I have the bitrate mentioned when you Disable Link at shutdown (link Dashboard) to fixed 100Mbps. In OTT, I have Adaptive GPU Scaling=Off.
With ODT, Oculus Link portion is Low,2912,Default,0,0,0,Enabled
Make sure you run the HUD while flying (well, sitting still, ready for takeoff) set to show Pixel Density which in my case shows 2734x2768 even though the MSFS VR Render Scaling shows 1504x1522 (higher * .55 = lower).
My test case is simply the Cessna 172 with G1000 at KCRQ with only high level clouds at takeoff RWY24. I make sure that the FPS is very steady at 24FPS. I watch the HUD Performance option to make sure there is no variation. Again, this is a must for ASW to be as smooth as possible. With no ASW, my FPS is more like 30 - which is OK for out the front windshield but not for looking out the side windows and aiming straight down.
My Nvidia driver = 511.23
