Everyone online says the difference is like 5-10%. But in my experience using on nvidia rtx 20 it’s always 20-25% fps loss compared to windows. Regardless whether i’m bottlenecked by GPU or CPU, on DX11 and DX12 games, it’s always 20-25% FPS defecit. Is that expected?
Using Wine-GE 8.1X with latest dxvk, d3dvk with bottles manager on fedora with nvidia drivers.
It actually depends on several factors. Surprisingly, games that are heavily CPU bottlenecked often run better on Linux under Proton than the native Windows version.
That being said, for games that are GPU bound, a 20% deficit on a Nvidia GPU is actually about what I’d expect.
