VR settings for Quest 3 with RTX 4090

[CMDR Darth Vater]

Hi folks,

since the recent update removed some bugs, I wanted to give VR another try. Now I am stuck with 72 Hz no matter what I chose:

And thats the result ingame with HMD 1.0 and Supersampling 1.0 - which seem to be a mediocre result:

Am I correct, when I assume that performance headroom should be 100%?

ok, that's a bug from Quest, I had to go on Beta / Public Test Channel to solve that.

With Virtual Desktop and many games on the Quest itself, if you enable battery saver it defaults to 72Hz. Don't know if that's applicable/helpful in your case or at all but thought I'd mention it anyway for future searches from others.

Energy saver was not enabled. It was the recent patch. I found with some searching on Meta's site many requests and then people came with my mentioned workaround.

Anecdotally, the Quest 3 UI and settings I can see here look similar to my Pico 4U GUI, right down to the colour scheme and window decorations. Also, the perf overlay looks exactly the same as mine. I know they have the exact same SoC with the Broadcom Snapdragon XR2 but I didn't think the software GUI would be the same. P4U also drops to 72Hz in battery saver mode.

Du you have some recommendations on ingame and Oculus Debug Tool settings?

Hey CMDR Darth Vater, any chance you have a link to the oculus forums talking about this?

There are some more I believe, but this mentions it, too:

Re: Quest 3 link cable stuck at 72hz.....

Joining the Public Test Channel fixed it for me

communityforums.atmeta.com

After the set to public testing you will receive some updates which fixes that issue being stuck to 72hz

Thanks for figuring all of this out.

I'd HIGHLY recommend running at 72hz. Then, jack up supersampling as high as you can while keeping your FPS 72 or higher.

Any chance you've noticed some weird framerate issues with Odyssey and terrain generation in the last week or so? Everything look like it should be good, my 4090 is barely at 40% utilization, only 1/3 of VRAM is being used, and CPU looks fine yet headroom is crap and I am getting significant frame drops. Haven't touched anything and in fact I am on lower rendering settings. Kind of weird.

I still need to test. But the last time I had the same experience. CPU/GPU, RAM and VRAM have got still a lot reserves. But headroom dropped really to the bottom / dark red.
