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.
Not necessarily, as many badly optimized Linux games run worse than the Windows version through proton.
And even then it’s usually not wine that makes games run slower, but the conversion of Direct3D to Vulkan (DXVK, vkd3d).
