Since the last patch for Marvel Rivals, I’ve been having trouble getting the game to launch on Steam. Whenever I hit the “Play” button, it just changes to “Stop” as if the game is running, but nothing actually pops up. I was playing just fine before and having a great experience with it on Linux using Proton.
I’ve tried various troubleshooting steps, like switching Proton versions and adding different launch commands such as SteamDeck=1 and PSOCompile=1, but nothing has worked so far. Here are my specs: I’m using Mesa 25.1.0-devel, Proton experimental-bleeding-edge, running Nobara Linux 41 (KDE) (Wayland), with an AMD Ryzen 5 5600X CPU and an Intel Arc A750 GPU. Some people have mentioned that AMD setups are getting the game to run, so I’m wondering if my GPU might be the issue. Any assistance would be greatly appreciated!

Have you heard there’s another patch coming out tomorrow? I’m hoping it addresses this issue since so many are experiencing it right now!
Have you checked your launch commands? It’s crucial to get the syntax right. For example, my launch options were formatted like this: gamemoderun mangohud SteamDeck=1 %command% -PSOCompileMode=1. I initially just used -PSOCompileMode=1, but had to add SteamDeck=1 to get it working recently. Double-check that you’re using the correct format!
I’m facing the same issue too, so you’re definitely not alone here! Hopefully, the next patch will sort it out for us.
I ran into the same issue last night. Using SteamDeck=1 in the right way helped me fix it, so make sure you include %command% in your launch options. It seems to make a big difference!
Good tip! I think using the correct command combination matters a lot. I might’ve just made a typo and overlooked it.
