Haven't tried FW yet, but DF said they preferred Quality mode on Forza Horizon 5 (Series S in particular) and I heavily disagree with them after trying both modes. It's weird to find myself disagreeing with DF nowadays.I always go 60 whenever I can, even if DF said they preferred quality mode.
I went by DF's suggestion and tried resolution mode, was a rough hour or so to adjust but now it's smooth sailing and the game is gorgeous.
