I’m having trouble launching Marvel Rivals on Steam since the last patch. When I click the “Play” button, it changes to “Stop” like the game is running, but nothing actually pops up. I was enjoying the game on Linux with Proton and even told my friends how great it was! I’ve already tried switching Proton versions and adding some commands like SteamDeck=1 and PSOCompile=1, but nothing seems to work. Here’s my setup: I’m using Mesa 25.1.0-devel, Proton experimental-bleeding-edge on Nobara Linux 41 (KDE with Wayland), and my hardware is an AMD Ryzen 5 5600X with an Intel Arc A750 Graphics card. Could my GPU be the issue? Any help would be awesome! Thanks!

Are you sure you’re using the right launch commands? You might be missing the %command%. I ran into a similar problem before, and just steamdeck=1 didn’t work for me. Make sure you added it properly, like this: SteamDeck=1 %command%.
There’s another patch coming out tomorrow, so maybe it’ll fix this issue? Fingers crossed!
I had the same issue last night! My fix was to add SteamDeck=1 to my launch options. So my settings look like this: gamemoderun mangohud SteamDeck=1 %command% -PSOCompileMode=1. Before, I only needed -PSOCompileMode=1, but now it seems like I need both to get it to work.
I’ve had no luck with it either. Just not launching for me. Might need to wait for the next patch or try different setups. It’s definitely frustrating!
Oof, I feel so dumb! I realized I misspelled the command. Thanks for pointing it out!
