Not many because there's still translation overhead - unless you have very good CPU, the results will be slightly worse.
It actually happens more than you'd expect.
Sometimes you even get fewer bugs on Proton.
One of the best examples was the release of FF7 Remake - it had really bad stutter on release on Windows... but not on Proton.
People even used DXVK (which is part of Proton) on Windows in an attempt to fix it.
I know it happens, but it's rare. Other example is Nier:Automata after valve created super fast shader compiler for AMD cards - game is so unoptimized that saving CPU cycles on shades not only compensates for overhead but also exceeds windows performance.
Again it's rare and relates to poorly coded games
You would think so, but Windows 11 is so bloated out so badly that I actually got much better performance on Linux for most games I play. I've only found 2 games so far that run better on Windows than via Proton on the same hardware.
Windows 11 24h2 update completely screwed all game performance for me so badly I had switch.
I'd imagine it would also depend on how overpowered the CPU and ram are. If you are running a xx60 card on the latest $2000 CPU and like 128GB of high speed ram, there's probably be little difference. But with more balanced hardware combos, the overhead of the OS itself could make a significant difference. Granted, I'm assuming the OS's have a negligible impact on any brand new dGPU.
