I played with the games 60 fps cap on both Desktop and Steam Deck. Performance on my Desktop was perfect at 1440p max settings after setting my monitor down to 60 Hz. I ended up settling on the default settings for Steam Deck, which was medium without anti-aliasing at 720p. Some worlds at these settings on Steam Deck could drop slightly below 60 fps at times, but I didn't feel it was enough of a hinderance to reduce settings furthur.

The game does do the cardinal sin of including graphics configuration files in the steam cloud backup, so each time you go between systems you'll need to reconfigure the graphics settings for the current platform.

Also for reasons unbeknownst to me the game requires an internet connection, which was a problem the one time I tried to play the game on Deck away from any wifi networks.
