OpenXR-Toolkit VS ALVR

Afaik you only need to have a developer account. It's not official but it's through the OpenXR toolkit. https://github.com/mbucchia/OpenXR-Toolkit

Right here:) You probably also want OpenXR-toolkit, and maybe OpenComposite to replace SteamVR entirely.

Download and install OpenXR Toolkit from https://github.com/mbucchia/OpenXR-Toolkit/releases. Optional but allows for extra performance tweaking.

WARNING here! You want to have Motion Projection Enabled in both OpenXR AND in ToolKit if you want to avoid a bug, I posted on the official OpenXR Toolkit github. IF you are a motion reprojection user, and you don't have these both enabled, it will "stealth disable" your motion reprojection completely if you ever exit VR and re-enter VR (using CTRL-TAB) without closing down MSFS and starting it up again.

On Gitlab, the VRNeckSafer developer stated that he uses a function to perform the rotation that's not currently available for use in OpenXR...he hopes that it will be added to the OpenXR Toolkit at some point, but while they will consider it it's low on their priority list.

You can override the behavior of the OpenXR runtime to make it use your own controller inputs via an API Layers. This is something that my OpenXR Toolkit project does, where I translate input from a Leap Motion hand tracking device into simulated VR controller inputs.

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.
