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.
