Here's my report:

1. Overwatch -> works great in Proton, albeit about 20% slower than Windows

2. Factorio -> works great natively on Linux, maybe even better

3. Warframe -> works okay in Proton but crashes sometimes

4. Call of Duty (recent) -> kernel anti-cheat both fails to stop cheaters and refuses to work on Linux

I tried living the Proton lifestyle for about 2 years, from around 2019 to around late 2021. Then I just dug my old computer out, reinstalled Windows 10, and went back to using Windows for games.

As a counterexample, I switched to Linux in 2013 for all use cases, gaming included, and haven't looked back. Many of my favorite games do have native Linux builds, but I've had little issue with those that don't.
