I don’t have hard numbers, but my understanding is that in general, Proton is more receptive to hacks which get stuff working, or working faster, but that aren’t proper solutions. WINE has a greater preference toward correctness, so compatibility is a bit worse, as is performance.
Note that this isn’t vkd3d-proton, the d3d12 implementation that Valve’s Proton and most gamers are using.
Is there much difference? Performance compatibility etc?
