Sorry to be the one to tell you that gaming on Linux since the last 5 years made incredible progress, in some cases with better performance and only gets better, instead of Windows and not just for gaming but also for everything else lol
Anyway, them contributing to the kernel doesn't mean nothing, as the project is open to everyone instead of their operating system, they mostly focus on their projects like WSL and Azurefor their benefits.
I'd like them to make real progress to the Wine project, which anyway goes without them, as always has been.
Anyway, since I don't want to be an ass and off topic, I confirm that actually runs fine for me with no real peformance hassle.
RTX 3060 NVIDIA GPU on an optimus laptop, Lutris + 7.2.2, over 80 fps stable.
Probably your wine setup is messed up somehow, and this game is definitely not the issue.
Never found a game on this site which doesn't run with Lutris, I always update everything including drivers and lutris itself.
