ALVR VS OpenOVR

They also achieve very low latency, I didn't follow every single optimization they added but it basically boils down to a few encoding tricks (better image in the center, accept blurriness in the peripheral vision), good network infrastructure, and hardware decoding / encoding being really fast.

To use steamvr on flatpak I used this tutorial . There was a disclaimer that nvidia GPUs are not supported, but the guy that suggested it has a 3090, so it might work for me too.

They have a Wiki page on GitHub with a settings tutorial and troubleshooting. A downside with a lot of open-source software is that it's relatively difficult to setup but it might fix some of your issues.

You can play wirelessly using Air Link, Virtual Desktop, or ALVR.

They also have a detailed wiki page on GitHub

Quest 2 needs some workarounds (dev mode account), but once you've done those you can just install ALVR (I recommend nightly). As for the games, check ProtonDB. Some VR games (Pavlov beta, for example) have EAC that blocks proton. Some VR games don't work with ALVR due to https://github.com/alvr-org/ALVR/issues/1392, like the Pavlov beta and Crawlspace. Just install the proprietary NVIDIA drivers and use Xorg and most things should work fine. Steam has Proton, which lets you play Windows games with high performance.

Wrong version, you need the openVR version. I think this is it. https://github.com/avaer/OpenOVR

From what I've experienced giving technical support to Oculus headsets users is anyone who's using SkyrimVR or more importantly mods should use open composite as it bypasses SteamVR and gives a great boost on FPS... Not having steams bloated systems makes it much better and quicker to load... Once you have open composite installed I used the DLL from the site not the system wide as I'm not wanting it with other games... Open Composite This is basically dropping a DLL in then main steam folder, remember to backup the original incase you want to go back... And remember you can also go to your game in steam library and turn off the screen overlay not many people use it when in VR...

Open composite is an alternative to Steam VR. It's more lightweight, so helps with performance. https://github.com/avaer/OpenOVR
