I am having 20 fps more in Linux with 4k screen when compared to 2k in Windows. Didn’t believe my old GPU could get better over time.

I find this hard to believe. Generally speaking, games run slightly slower on Linux (that's on Arch with latest Nvidia drivers). Usually, the difference isn't really noticeable, and several rigorous benchmark show that even though average FPS is single digits lower, the standard deviation is also smaller. This may be due to Nvidia not performing as well on Linux, the worst impact I have seen is on Helldivers 2 (at least 15 to 20% lower FPS).

If you have an older game which still uses dx9, dxvk can give a decent little performance boost - even if you're running on Windows. It's kind of magical that adding a translation layer is able to improve performance.

In more modern games using dx11/12, I've always noticed a small loss like you'd expect. I haven't properly benchmarked any but I suspect a game with native Vulkan support would do pretty similarly, and might come out on top due to CPU load.

Old games already run at insane frame rates on modern hardware, so while it's impressive from a technical standpoint, the performance boost is largely irrelevant. Even with a small loss, Proton is completely worth it -- no more Windows spyware, activation/registration nags, cloud/AI bloatware.
