Best setting for Rog Ally?

I have played the game on desktop PC with a 4090 and performance is of course top grade. Then I played it on Rog Ally X and it seems slow. I changed Graphics to 720 instead of 1080 and it did imrpoved some fps but the graphics seemed to be coarsed a lot. For those who play on Rog Ally / Ally X what settings you recommend to play this game for best fps / performance? Thanks.
