I am generally pleased with the Quest 3 with one exception. The shimmering is distracting. Ive tried numerous settings to no avail. I am getting excellent fps, smoothness and graphics except for the shimmering. 5800X3D, RTX 4090. VDXR with MSI AXE6600 router. Coming from a G2.
Anyone have any success to share? Thanks

I was able to eliminate shimmer in my Quest 3 by disabling Asynchronous Spacewarp (ASW).

Also with a rtx4090. Ive found the best way o get rid of shimmer with both my QPro and Q3 is to use dlss/balanced. If you switch between TAA and dlss you should see a pretty big difference.

To improve dlss/balanced cockpit clarity I’ve found adding 1.4x super does the trick. I’m using Air Link at 200mbps dynamic plus I add 5mbps dynamic offset in ODT (seems to help stablize my bitrate). I use OTT to sett ASW = off and set SS = 1.40. My oculus desktop app device settings are 80Hz with the res slider full right. with msfs I turn on rear projection (depth) and end up with a very smooth 40fps, even low flying heli’s in cites like NYC and Tokyo.

I have recently tried VD again with it’s new vdxr runtime and av1 (with my Q3) but I’ve found I get better, more consistent results using the Oculus openXR runtime. Also, since upgrading to a rtx4090 I haven’t found the need to use the openXR Toolkit.

In your case, if you prefer VD then you may need to use the openXR toolkit to upscale your resolutions in order to improve dlss/balanced clarity.

I also still run a DP wired +4yo Vive Pro 1 (amoled screens, etsy lens mod, and index controllers). To get a similar benefit I just manually add 350% SteamVR visuals and disable advanced super sample filtering. My good old VP1 still works pretty well and it’s pretty hard to beat for blacks/contrast during night flying. Still as a bit more SDE than I’d like though.

Yep, even Asobo a while ago suggested that (the then still upcoming) DLSS was the recommended “fix” for shimmering. Lots of people were complaining about it at the time.

Thanks for all the info, I’ll try changing some settings.

I already had ASW disabled, DLSS Balanced made a significant improvement. I didnt have time last night to try further tweaks as mentioned but will soon. Thanks to all !

If you are using Toolkit you can run NIS and 20% sharpening. Shimmer is usually because of double sharpening, AMD FX and something else. I set my SIM VR tab AMD FX sharpening to zero, then use toolkit to NIS 20%, but I also run DLSS with DLAA at 3120x3120 Override in Toolkit System tab, no Super Sampling. DLAA is DLSS algorithm without Super sampling. This way you send a pixel perfect size with sim at highest settings, except Trees and Grass, and great feel with no shimmer.

DLSS Quality should be even better since higher res = less shimmer usually. Might be a performance trade-off though.

The sky shimmer in clear conditions seems to be a common problem with Quest Headsets when paired with a 4090. The fix to get rid of the sky shimmer is a simple fix in the usercfg of MSFS.

set SHARPEN from 1 to 0 under “post processing” and the problem went away after I let it go for months.

{PostProcess
	Enabled 1
	EyeAdaptation 1
	ColorGrading 1
	Sharpen 0
	Fringe 0
	LensDistortion 0
	Dirt 0
	LensFlare 0
	FilmGrain 0
	Vignette 0
	LensBlurMultiplier 1.000000
	FringeMultiplier 1.000000

However I need to figure out how to do it for 24 since it is back in 24, but the 24 usercfg does not seem to have the “post process” section, the other sharpen values do not fix it. its only the “post process” SHARPEN value in the MS2020 cfg.
