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 āVR Bibleā 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 canāt expect top end, but this is pretty unusable in VR. Something is bottlenecking or otherwise really choking my system for VR, but Iām 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 Iām 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 donāt 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:
- 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.
- 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 doesnāt destroy the VR in the headset! Airlink on my system doesnāt like running at 200, but that is just poor wifi. The cable now runs solid at 500, havenāt 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.
Iāll 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).

Hi, A few weeks ago I started testing VR with a setup quite similar to yours (RTX 4070 Ti, 64 GB RAM, etc.), and Iāve run into similar issues regarding brightness, contrast, and sharpness. Iām still in the process of tweaking and experimenting, but Iām very interested in your experience since youāve already made good progress with your configuration.
Have you achieved any further improvements since your last post, especially in terms of colors, stable performance during flights, and sharpness on the Quest 3? It would be really helpful to know which adjustments worked best for you to refine the visual quality in VR.
Hereās where I am currently at:
Quest 3 set to 80Hz, 5408x2912 resolution.
Using Link cable
ODT -
Open XR Toolkit - using sunglasses
Screenshots for Nvidia attached, MSFS in following post
Sorry about the backwards order of the shots. The Image sharpening was a registry tweak mentioned in this forum, not sure it did much.
My performance on quest 3 using VD only is that performance in 2020 is the best itās been. I get the desired frame rate and no stutters - performance I strived to for several years
however contrast and the brightness in the sim has always alluded me as to ādimā down the graphics and be more realistic - any further thoughts
My set up
Quest 3
CPU: AMD Ryzen 9 7900X3D
Cooler: Corsair H150 RGB Liquid CPU Cooler
Motherboard: ASUS TUF GAMING B650-PLUS WIFI
GPU: Gigabyte GeForce RTX 4070 WINDFORCE OC 12GB
Memory: CORSAIR VENGEANCE RGB DDR5 RAM 64GB (2x32GB)
Storage: WD_BLACK SN850X 2TB NVMe M.2 SSD
PSU: MSI MAG A850GL PCIE5 Power Supply (850W)
Case: CORSAIR 6500X Mid-Tower ATX Dual Chamber PC Case
Fans: 6x Corsair iCUE AR120 RGB Digital
In VD, change the gamma from 100 percent to 70. That fixed it for me.

Thanks - I have tried that many times. I wonder if it could be an NVIDIA problem?
If your still looking for better clarity in Quest3 i found recently that OXRTK isnt really necessary.
Im using 9800X3D, 5080 and i found that using a wired link i can get good clarity by setting the Meta app resolution to 1x then in the ODT enter twice the horizontal resolution value into the encode resolution width.
Then tweak your in game settings from there.
I hope this helps

Force mipmap off? What is the argumentation behind that, just curious.
And reduced FOV, doesnt that give you Black borders?
I havent touched mipmap, thats just how it was. The FOV only gives me black borders if I go below 0.85, so 0.80 will give a binocular shape. It works very well for me

hi - I am going to try your settings later tonight
I saw improvement in the sim with your adopted settings especially around FOV

Im glad it helped. It seems with Quest less is more.
I got better results without OXRTK. Frame rate was also steadier ( i stick around 35-40fps as it fine for my needs). Gave me more GPU headroom aswell.

Back today to dark lense when looking upā¦
You did input correct values again before use? They dont save between sessions.
