Not sure if you're being sarcastic, but have you seen Spider-man on performance mode in 120hz with VRR? Framerate reaches 100fps
Same with the fidelity 40fps mode; it can go up to 50fps...
I'm not being sarcastic at all. I know really it's not space magic it's changes to the dyanmic res scaler.
But my TV shows both fidelity and 30fps going above 60hz, like you said performance was 80-100
Granted, I haven't played through either of them fully since the patch as I've played them both to death already.
