Cyberpunk 2077 2.0 landed recently, and now I've had time to play with it here's a look at how it runs on Steam Deck and desktop Linux after the update. The good news is: it runs out of the box with Proton. My testing has been with Proton Experimental.

Quick tip - want to skip the launcher? Add this as a Steam launch option: --launcher-skip

For the Steam Deck, I've been testing it on SteamOS 3.5 Preview, where it does in fact run quite well. On Low and Medium, it can for the most part stay above 30FPS and a lot of the time when you're not doing explosive action in the open world, it can even stick around 40FPS. However, even on the Low settings, intense open world action will bring it down but Medium with FSR2 keeps it pretty smooth.
