Ever since the issue with Apex not launching was fixed, I'm not able to play any EA games with Steam Proton.
Apex, which doesn't launch through the EA app flickers immensely on Fullscreen and Borderless Window. Flicker goes away when windowed, but the GPU utilization regularly goes down for a few seconds, dropping the FPS.
Titanfall 2 and Battlefield 5: I get an EA app screen that says "Preparing Game" which exits after about 1 minute (I think steam is timing it out).
Proton logs show some errors about not being able to load a few DLLs but research on the internet points to them not being relevant.
I have tried on all combinations of below:
Hyprland, KDE, and Gnome. All Wayland.
NVIDIA 545 and 550
Linux-zen 6.7 and 6.8
Arch Linux and NixOS
Proton 7 through Proton Experimental as well as GE 9.1 and 9.2
Not sure about this specific issue but whenever I had issues with EA games in the past I would nuke the compatdata for the game and that usually fixed it. Make sure to back up your save file if you do that.
Weirdly, anything after Proton 8 was not able to properly recreate the compatdata folder because of a bug in the script. I fixed the bug and get it to generate the prefix but the issue with the game not launching is still there.
On NixOs you may need for var in $(printenv | cut -d= -f1); do export $var=$(echo ${!var} | rev | cut -c1-1000 | rev); done ; OPENSSL_ia32cap=~0x20000000 gamemoderun %command% +m_rawinput 1 -novid
