Funnily enough, the game is basically stuck at 60 FPS for me, even though I have a 144hz monitor. Everything I look up says the game engine wasn't configured to go past that and anything higher requires mods and such for it to be supported. I'm a relatively modest gamer who plays a lot of Switch, so as long as it's consistent I don't mind, I just keep it at 60.
Glad to know Starfield can go higher, but my computer isn't amazing so newer games just don't stay consistent above 60, I just cap Starfield at 60 as well.
