I'm having huge cpu hunger on steam deck. 12W on cpu just for tutorial. 60 fps save data, 50 fps movies, 50 fps overworld, 20-23 fps tutorial. Lowering graphics doesn't help.
Proton experimental, 8.02, 7.41-GE
Apparently spoofing a Steam Deck by adding SteamDeck=1 %command% to the launch options improves performance on non-Deck machines.

Doing this on my steam deck added like 5 fps in movies and 2 fps in tutorial for some reason.

It mainly benefits desktop Linux users because it's already enabled for the Deck by default.
Seeing a similar issue also on desktop. Intel 4790 cpu and amd 5700xt gpu. The gpu stays at 800mhz (2D clock speed). Getting 120 fps in the save game picker, 40~ fps in the level select plaza and 20~fps in game.

This worked on my desktop. Get 120fps all the time now. No clue what's going on.

Compatibility Report
System Information
I confirm:
Proton Log: steam-1730700.tar.gz
Symptoms
The game struggles to run at "playable" framerates.



30-50 FPS at save select
15-30 FPS on plaza/level select
<15 FPS in-game
additionally I've tried multiple proton versions: 7.0, experimental, GE, with similar results. The game runs fine on my steam deck which makes this issue even more odd...
Reproduction
reproduction should be straight forward.
