Proton Hotfix updated for Resident Evil 4 remake, Steam Deck needs SteamOS 3.4.6 Preview

Valve developer Pierre-Loup Griffais mentioned that they've updated Proton Hotfix, which should allow the new Resident Evil 4 Chainsaw Demo of the remake to run on Linux and Steam Deck.

On Desktop Linux, simply selecting Proton Hotfix should be all you need as Griffais mentioned on Twitter. For Steam Deck players though, Griffais also clarified you will need to opt into the Preview update. I covered how to do that and what else was in SteamOS 3.4.6 preview in my previous article and video.

Testing out both, I can confirm on Desktop and Steam Deck the Resident Evil 4 Chainsaw Demo does seem to load up and work with Proton Hotfix, which on Steam Deck is now set as the default but you need to do that manually on Desktop in the Properties -> Compatibility menu.

Desktop Linux:

However, it's not exactly very stable right now. With MangoHUD enabled, it would instantly crash. I spotted various graphical issues too, like your character randomly being stretched across the screen and at one point it completely froze. So it's far from playable there.

Steam Deck on the other hand, was far more stable with the AMD GPU and the Mesa drivers but performance is quite problematic right now even with lots of settings turned down (and AMD FSR turned on too). No doubt it will improve as a shader cache is built, and as Proton is updated further.

Nice to see Valve continue to work quickly to improve compatibility but seems there's still some ways to go yet on this particular title.

You can pre-order it on Humble Store and Steam.
