ProtonDB doesn’t have any report yet but YouTube is full of videos of content creators that got early access to the game. I was curious to know if anyone tried it with Proton and how it works…
EDIT I just installed it and it seems to work out-of-the-box for me on Ubuntu 23.10 with a AMD 7900 XTX and AMD 5800X. I’m getting around 55 fps at 3440x1440 with almost everything high beside having disabled V-Sync, DoF and Motion blur. AA set to TAA 2x.
It ‘opens’ on Steam Deck and Mac but it runs poorly even before really starting your city (City Planner Plays tried it to benchmark), so it appears that it is at least compatible with Linux via Proton.
