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.
PSA you can download a savegame with a city pop of 100k to check how well the game will run in later stages. By doing this you can check it and refund it if necessary.
