Slight stuttering, solved by using proton GE
SteamOS - Pre-release branch. Works just fine with no extra tinkering. Battery life was like 2 hours or so. Temperatures were 76-79°C
50 FPS cap, volumetric lighting - OFF
Overall expirience is great, feels smooth and no lags or errors detected.
to save power and improve performance, I lowered shadow settings as volumetric lighting uses a lot of the gpu, after doing so even near beacons my framerate tends to hover around 60 fps
the game doesn't seem to support 16:10 aspect ratio but still "starts in it" leading to a few UI errors, easily fixed by changing the resolution to 720p manually
Game assumes a standard 16:9 resolution but renders fullscreen on the Steam Deck causing overlay effects that are supposed to cover the screen to leave gaps at the top and bottom.
Noticeable drops from 50-60 fps down to 30-40 fps when near lit beacons.

Can't go past the costumization screen
When in the menu everything works fine. Settings work, and you can even start a new game. But when you start a new game and it loads the costumization screen the game crashes
