It worked well for me. I've heard the same stories and understand in some cases a the better version of a driver ends up being an older one, instead of the latest, so there are some quirks. But the games I tried all got great performance. Experience will vary widely by game, however. From the lookups I've done on ProtonDB so far, I do understand in some titles I may lose some fps- but it's yet to have been a big enough hit to bother me
