Slight stuttering if not using discrete GPU

Modified controls
small amounts of lag

Runs about as well as I should expect; this game definitely needs a little bit of work namely the ai unrelated to the proton & controllers
Added some steam inputs to get controllers to work
slight lags extremely minimal all things considered though
It really needs the steam input
Proton hotfix, 3440x1440 fullscreen can be set by manually typing in the resolution into input boxes.

The game forcibly runs on my integrated GPU rather than the discrete one, and performance is terrible as a result.
If I could run the game on the discrete GPU instead it'd be fine, but there doesn't seem to be a switch for that.

Works pretty well out of the box
Turning my bluetooth headset on and off again fixed the audio issues. Though, I do have to do this every time I boot the game up (may be an issue with the HyperX Cloud Flight S specifically).

I haven't tried handheld mode for SteamDeck (doesn't seem like the right game for it at this point).
at 1080p it stays between 30 and 50 fps, but loading into an area drops the frames competely and it takes a few seconds to recover.
But yes it runs and plays on SteamDeck hardware. This is just an initial report after an hour of playtime.
