Steam makes it easy to get a full refund for a game you don't like for any reason. So there's no risk in trying an install of a game that might not work well on your below-specs device, but then you shouldn't give it a negative review.
Unless most of the problems come later on, after the 2 hours game time.
I've heard about multiple games that where steamdeck verified but the performance choppy. If it can't hold a steady 30fps, a game shouldn't be steamdeck verified in my opinion.
