AC works fine just requires a little extra setup, either use this script[0] or use the latest GE-Proton (with a fresh prefix), I recently updated protonfixes to fix a CM/CSP issue. The latter is better as newer Proton has some definite performance improvements.
Fresh should mean creating a new prefix. For example, Proton-GE enabled wow64 in Wine by default, but it requires recreating the prefix to use it. Should be easy enough with Protontricks or even Winetricks.
Yes very much this. It is possible to modify an existing prefix but there are quite a few things to do, it's easier to back up savegames and game config files and then create it anew.
Thank you very much to both of you. Got it running flawlessly with CM on Steam Deck OLED at 90fps using GE-Proton10.34 and LSFG-VK for frame-gen. This one goes straight to the top (alongside DR2.0 and AC Rally) as favourite gaming on the go.
In my (admittedly limited) experience, it does run, even with quite comparable performance, but getting a wheel to interact with the game has been a bit challenging. But this could be resolved with a custom driver for my specific hardware.
Using the community standard mod manager seems to resolve the UI jank by completely bypassing it.
yeah, I've heard this too.. and I'd rather my rig just works rather than try and stuff around making it work under linux + I know iracing is cooked anyway, and I've spent enough money on the rig to just want it to work, and not get stuffed over by some anti-cheat, maybe soon
