oversteer VS ALVR

Did you try oversteer?

I do not know lots about wheels in Linux, but I had come across this one day which may help you… https://github.com/berarma/oversteer

Is it possible to install Oversteer on Batocera and access the settings using the F1 menu?

What force feedback wheel are we talking about? Some are supported in the kernel and some have drivers on github. More info here.

A good place to look at is the oversteer github. It seems generally its only Logitech wheels which have good support on linux. Certain Thrustmaster and Fanatec wheels seem to work at least to some degree. However the t128 in particular is not mentioned anywhere

Oversteer, it's a Linux program which lets you use wheels. https://github.com/berarma/oversteer

For the wheel, I have a G29 which works without any issue. Rotation and FFB gain is customizable easily with oversteer which support G27 as well.

Unsure how easy to setup extra linux apps on SteamDeck, but this is one tool for FFB in linux : https://github.com/berarma/oversteer

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

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.
