As per title, I am currently playing on Linux using Proton GE Custom latest version (8.27 but also tested 8.25).

My experience is the following.

Specs

• Ryzen 7 7730U (8c/16t) Laptop
• 16GB RAM (14 RAM + 2 VRAM)
• Decent performance SSD
• Ubuntu Linux 23.10 (with Xanmod 6.7 x64v3 Kernel)
• Wayland

Experience

• Could not test anything above Low settings due to severe stutter even in the menu and 95% RAM which lead to PC being stuck

• At low settings with different resolutions (from 720 to fullscreen 1080) i have 80-85% RAM usage (starting from a 21% base load) and 25-ish FPS performances

Workarounds

• Once you get the game installed, add it to Steam as a non steam game pointing directly to the game .exe, compatibility forced to Proton GE or Proton Experimental
• If it gives you some Visual C++ dependencies error, use ProtonTrick to install it in the Steam prefix
• I did not find any performance tips and tricks

Conclusion

While being playable, I feel that the game can see huge improvements on Linux. However, I think there is also a lot of telemetry (local or remote) / logging in the mix as every pre-release version has (looking at you My Time At Sandrock) and probably the graphics part (especially the engine part) needs to receive some improvements too, so I bet in about 1 month we will see a steady 40-ish FPS with those settings

Cheers
