This game runs and play flawlessly with default config, the only "issue" is the presence of some chromatic aberration with a green bar at the bottom of the intro videos and prerendered cutscenes like the one at the beginning of a new playthrough. Although this isn't a gamebreaking bug and basically irrelevant for most of the playthrough, out of curiosity I tried switching to the latest version of Proton GE and this last issue is now completely resoled. As to why this game is better here, this game runs smoother and faster on Linux, probably thanks to the better CPU utilization, I can even get as up to double the fps in the most cpu demanding areas compared to Windows 10/11 on the same PC. Using DXVK on Windows got me 90% there fps wise but the game still felt less smooth on it compared to Linux, because of some really small microstutters.
