I’ve been having issues with Marvel Rivals since the last patch. When I hit the “Play” button on Steam, it changes to “Stop” but the game never actually launches. It seems like it’s running in the background, but nothing pops up. Just yesterday, I was bragging about how well it was running on Linux with Proton, so I’m pretty frustrated. I’ve tried switching Proton versions and added various launch commands like SteamDeck=1, PSOCompile=1, and gamemoderun, but none of that has worked. Here’s a bit about my setup: I’m running Mesa 25.1.0-devel, Proton experimental-bleeding-edge on Nobara Linux 41 (KDE) with Wayland. My CPU is an AMD Ryzen 5 5600X, and I’ve got an Intel Arc A750 GPU. I’m wondering if this could be related to my GPU since I’ve seen other AMD users are running it fine. Any help would be really appreciated!

I also faced this problem. Just adding SteamDeck=1 didn’t work for me, but when I included it with %command%, it did the trick! Just check your command syntax if you run into this. It’s easy to miss details and it makes a difference!
I had no luck with my setup either. At this point, it seems like a bug in the latest patch. I heard there’s another patch dropping tomorrow, so maybe they’ll fix it then. Let’s keep our fingers crossed!
I had the same issue last night! My fix was to adjust my launch options. I added SteamDeck=1 to my commands, and it looked something like this: gamemoderun mangohud SteamDeck=1 %command% -PSOCompileMode=1. Initially, I only needed -PSOCompileMode=1, but it looks like SteamDeck=1 is now a must to get the game running properly.
Totally! I accidentally misspelled the command once and was so confused why it wouldn’t work. Double-checking can save a lot of time!
