It works great on Steam Deck. Change compatibility to "Proton Experimental". For battery usage, I set TDP Limit to 10. It should still be 60 FPS on medium settings.

I love Starlink, but it's a bit broken and abandoned on Windows. I basically play the Ubisoft Connect version on Windows and this version on Steam Deck. It plays great in handheld.

I love this game, I first got it day-1 on Switch, then eventually got copies on PS and Xbox for dirt cheap years later.
