Baffled with my Quest 3 setup - High GPU, terrible brightness/contrast

New to 2024, running very well on 4k monitor, but poor in VR
I7-13700K, 64G, RTX 4070Ti 12G
Quest 3, Link cable, 72mhz, auto

Very low performance, GPU seems to be >90% most of the time in VR.
MSFS vr settings to low, details at 50.
Flyable if ODT Pixels 1.2, FOV .7;.7, ASW force 45/disabled, H.264, Bitrate 0
Going in direct from Oculus VR desktop (do not run Steam VR knowingly)

In flight, scenery appears extremely hazy - like flying in Canadian wildfire smoke - all scenarios, poor colors, poor contrast. Menu screens/intro videos way overly bright/washed out/have yellow color casts. If in flight, hitting ESC the resulting pause with options menu gives MUCH better display.
Have played with Quest brightness/contrast, but little improvement.

Lots of time trying Nvidia settings, various ODT settings, MSFS VR settings to no avail. Primary reference used is the “VR Bible” video by @TadeuPrimo.
Cannot change Encode Bitrate in ODT to anything other than 0. Any other value destroys the display in the Quest. Quest cable test always passes USB test.
I know I can’t expect top end, but this is pretty unusable in VR. Something is bottlenecking or otherwise really choking my system for VR, but I’m at a loss to discover what. Any suggestions?

Are you using openxr toolkit? To adjust contrast and brightness, I mentioned this in the video. This is an essencial tool nowadays only by this reason

If I’m not mistaken, you want your GPU to have high usage in VR. You are rendering at least 2 full scenes in each frame which is what the GPU is designed for. High heat is a different issue of course. You also don’t want all your VRAM used up. As far as openxr toolkit, the author has stopped support and clearly states it can be unstable, warns of its continued use. I fly in Virtual Desktop thru wifi and the experience has been far better than a wired quest link and it gives you nearly all the features of openxr.

Thanks to both for the notes - I was trying to start with the basics, before I layered on something like toolkit/VD.

But, I have made big headway since posting:

  1. Dug deeper into Windows graphics, and made sure to turn off all enhancements - HDR, hardware acceleration, game mode, power settings, etc. Even reset the colorspace the monitor uses.
  2. Reinstalled the Nvidia drivers as a clean install, to get back to defaults.

That got things much closer to a good space for colors/brightness/contrast in all vr screens. Still tuning to do, and it will never be as good as the 4K monitor of course, but useable.

A bonus - now I can set the bitrate, and it doesn’t destroy the VR in the headset! Airlink on my system doesn’t like running at 200, but that is just poor wifi. The cable now runs solid at 500, haven’t pushed it yet. GPU in MSFS menu screens in VR is now ~40-50% utilization. Of course I can tank it with too high scenery setting in flight, but that is just balancing.

I’ll play with the basics - Nvidia and ODT to find best compromises a bit more, but at least now am heading in a direction where I can think about the toolkit and/or Visual Desktop testing. At least there seems to be a place to stand now, even if not yet optimized.

(And, of course, seeing what needs to be retweaked for the monitor and the other non-vr games played).
