From my experience:

Linux > Steam > Proton > Windows Game

works better than

Linux > Wine > Steam > Windows Game

There's really no reason to be running Steam in Wine when Steam runs natively within Linux and Proton does the work for you for each individual game.

I can vouch for Proton. In some games, I can even get more FPS running on Proton/Vulcan DX emulation than natively on windows. One such example is Path of Exile. I should totally NOT be playing this game..
