Not a deal breaker for this kind of game but a 60fps performance mode on series x at 1080p would’ve been a nice option.
Playing TOTK right now on switch and it really proves how great games can overcome technical limitation. A masterpiece at 30fps is still a masterpiece. Here’s hoping Starfield can deliver as a great game first and foremost.
If the bottleneck is something like AI or physics calculations on the CPU then lowering the rendering resolution won't help achieve a higher framerate unfortunately.
I suspect most games shipping this gen without 60 FPS modes are CPU bound.
