This is an interesting one. On LMDE (Mint Faye), it will crash with an "oodledata" error (Unreal issue) on newer Protons. Dropping down to Proton 8-0-5 works - it launches, plays etc etc.
However on my Ubuntu (Linux Mint, Kubuntu) systems, nothing worked. It will always crash with the Unreal error even if I keep dropping Proton versions down. I have not tried with Arch or any RPM-based systems.
Running this straight on Windows 10 also gives the "oodledata" data error on launch, even from a fresh install of the game. Verifying files etc on Windows did not fix the crash. As it is, current version of SlavicPunk seems to be broken for Windows 10 (with newer hardware, AMD RX 7600, Ryzen 5 5600G etc), that may explain why the newer Proton versions gave exactly the same error when launching.
It just works stable. No tweaks needed.

Slow and stuttery
Significant stuttering except with Low graphic settings
The game opens and works and I was able to play for five minutes. The cutscenes either don't work, or else load really slowly. On Low quality I was able to start the first quest, but it's very difficult to play. Still, the team has promised a patch in the near future, that should fix similar problems on Windows, so there is hope!
