Works good
Works out of the box

No problems at all
If u wanna use mods, use protontricks to start the app with game setup

In short as this is a driving game, playing it with a keyboard is not suggested, controller support is sadly broken so try to avoid
Forget using Controllers or steering wheels, they will only detect half of the output then zero out to -1 or 1 on all axes.
In the end, this game runs great on Windows but not so much on Linux

gamescope -W 2560 -H 1080 -- %command%
When tested on zorin alt tabbing could crash the game, gamescope fixes it. Have not tried disabling gamescope on Garuda to test this.
I've been playing the beta for the next major release and it's been perfect. No unusual slowdowns, only the typical long drive lag. Additionally, hosting multiplayer worked perfectly from my linux pc meanwhile my windows friend was unable to host.
The mod manager (when not running the beta branch, as it is not yet updated for that) also works perfectly, just put it in the games directory and open it with protontricks.

A tip for any new linux users, make sure that if you're installing your steam games on a secondary hard drive that its not formatted as NTFS. Proton does not seem to play nice with the NTFS format, which wasn't immediately obvious to me!

Works almost perfectly
Don't know how you would set up the custom radio though.
gamemoderun %command%

Controller needs heavy remaping but even then it's super awkward to use.

The game worked out of the box
Slightly worse performance and framerates than on windows
No need to tinker unless you want to install mods
its a great game on linux basicly native preformance
Game runs perfectly.

only worked on proton 9.0-1, nothing else needed

Works Fine
Work Just fine solid FPS

You need to create your own mapping or download one from the community. It needs to be based on the Keyboard & Mouse config.

Runs smooth like smooth are tires in my Trabant.
Runs without any problem. Out of the box :D

Bugs in this game are a feature, not an issue. The game runs as expected
There is a multiplayer beta branch, it is VERY buggy (by default, its very early development) but it is just as playable as it would be on windows. Its as stable and actually runs better on Linux. Mods are also useable, no instability or outlying issues.

Runs perfect
Even mods work (Modloader not tested. I wrote one myself to load the mods from the original mod loader.)
Glitches - probably not related to Proton
Random slowdowns ~5fps
Lots of bugs and issues but they're not because of Proton or Linux gaming. Working "as intended" I think. I got multiplayer working with no major issues but had to choose public lobby for my friends to join
gamemoderun %command%
Can't install on NTFS but works perfectly on ext4

Didn't try wheel but probably will work, works fine ootb (for the most part).
Excellent
Just sit back and enjoy the ride
exclusive fullscreen crashes the game
runs very bad
multiplayer physics are buggy. might be linked to fps instead of fixedupdate
Worked out-of-the-box.
I swear, I could just start using the same report for almost every game.
Just make sure you have the lib32-nvidia-utils package installed. ("sudo pacman -Q lib32-nvidia-utils" to see if you have it, and if you don't, "sudo pacman -S lib32-nvidia-utils")
I wasn't able to launch it when installed on an NTFS filesystem, but when I moved the installation to an ext4 filesystem it launched fine.
Runs very great with no tinkering required. Looks smoother than on windows, and feels like there is less input lag.
Physics performance is noticably slow compared to windows
If you have the hardware to support the overhead of proton you should be good to go
Stuttering when game stutters
30-50fps with stutters and physics slowdown
May just be the game itself but physics seemed especially broken compared to when I played on Windows.

Game runs very well and is stable however be mindful of the performance if you don't run a higher end system.
Runs on 30-50FPS on very low settings.
