ALVR VS hid-fanatecff

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

https://github.com/alvr-org/ALVR/wiki/Settings-guide Goes in-depth about a lot of the features/settings

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.

But... sim racing is an exception. Most of the games will work (though not iRacing), but support for the hardware is not there. If you google around, you'll find a lot of projects like this one), that are clearly of the "well, if you compile this thing, and you tweak a bunch of configs, maybe it'll mostly work in some games most of the time, if you're lucky" variety.

- Installed hid-fanatec to get it working with FFB (https://github.com/gotzl/hid-fanatecff)

The fanatec wheel should be supported by this HID driver, but I have not tested it out. And the Rift S is just a no go.

Yep oversteer in combo with the hid-famatefff driver is likey the best bet.

there's oversteer: https://github.com/berarma/oversteer which says it works with your wheel once you also add this module: https://github.com/gotzl/hid-fanatecff

Fanatec Wheels, Probably the biggest update in 2021 we had, there is now a community driver on Github https://github.com/gotzl/hid-fanatecff That has the elite and sport working and appears to be experimental with the DD setups. I do not have a fantec wheel to test this.

The CSL DD has experimental support with this driver https://github.com/gotzl/hid-fanatecff

I'm using the CSL: DD, Logitech shifter and clubsport v2 pedals, there is support at the moment for the CSL DD https://github.com/gotzl/hid-fanatecff but it's experimental and some games don't work right now like the f1 games and beamng and I use simhub for my dashes which isn't on linux. so sadly there isn't much for linux options in my case.

Not completely true. There exists a driver for Thrustmaster T300: https://github.com/Kimplul/hid-tmff2 Other wheels I also have seen supported are some fanatec wheels: https://github.com/gotzl/hid-fanatecff

If your wheel pedal and shifter is of the Fanatec kind, there is a driver on github.
