Although for some of us this is a well-known problem, it has appeared again with the release of DOOM: The Dark Ages so it's worth a quick PSA to remind people about Denuvo activation limits with Proton on Linux, SteamOS / Steam Deck.
As of a few months ago (IIRC the timeline) Steam shows this directly on the game’s store page. You’ve got to scroll down for it a little bit, but it’s right under where it lists features of the game, E.G. single-player, controller support, etc.
This problem is solved by not giving money to devs who use denuvo. If you gotta resort to malware to sell your game, it’s not worth playing.
How do I know which do? (Genuine question.)

There’s even a Steam Curator you can follow who recommends against games that use Denuvo. https://store.steampowered.com/curator/26095454-Denuvo-Watch/
I literally came looking for this info. Ty for asking the questions and ty for answering them.
