Marvel Rivals sudden stuttering after a few matches.

Recently switched to cachyos from windows after getting fed up with microsoft again, and I managed to get Marvel Rivals to run good and decent on linux after tweaking some options, being able to average id say like 70/80 fps

However, as the title says, after 2 or 3 matches the game just starts to stutter really really badly? Like nearly unplayable bad. Restarting the game fixes it and i can play another 2 or 3 before it goes wrong and stutters again, but i really have no clue whats causing this. I have a Nvidia GPU which i know doesn't always play as nice with linux as AMD but i dont really think that would be the cause here.

These are the launch options im using: SteamDeck=1 PROTON_ENABLE_WAYLAND=1 gamescope -f -w 1920 -h 1080 -W 1920 -H 1080 --force-grab-cursor -- %command% -PSOCompileMode=1

If anyone has any suggestions or solutions it'd be a great help to me and whoever else comes across this post in the future
