Just some framedrops during loads, nothing major.

Give this baby a Platinum rating. Perfect.
using proton 7.0-5 from the compatibility menu, the staters are gone and the game works perfectly
prime-run mangohud %command%
runs under Proton 6.3-8, the original loading screen appears, a warning window appears, then the game crashes
prime-run mangohud %command%
removing the startup options does not change anything
prime-run mangohud %command%
If you do not give the game some kind of input, it's like a pause, does not go render the following frames and use game files. even if you constantly do something in the game, there are noticeable staters, sharp dips in fps.
even though i used prime-run in the commands, it doesn't seem to be what caused this

The game runs great and controls amazing on the Steamdeck, sometimes crpgs are tough to control with a controller but this game is fantastic with the default Steamdeck controls. 60fps/60hz I had it set at, started a new game and loaded my save games from PC, had no issues at all in 2 hours playtime.
Runs great without problems. There was a bit of screen-tearing at the top of the screen, but that seems to be a cross-platform problem.

Switching from Fullscreen (classic) to Windowed or Fullscreen windowed freezes the game.
