This guy right here has you covered.

A word of warning though, I played alternating between my beefy desktop and my steam deck, and the deck did admirable albeit at much lower settings. The only thing I simply could not play in handheld mode were street races. Frame rate and pop-in issues galore, it’s just too much for a little machine to process. Other than that the experience was great around 50fps.

Thanks, I'll try these.
