Nah that's sadly just 50 FPS x4 (=200). Without MFG the base FPS would probably be 60+ since it has a computational cost.
I'm playing at 1440P, so the 5080 gets 200 FPS with 4x.. lets add some extra for the 4090 and say it's 60 baseline with FG, then it will be 120 with FG on, which could be very borderline with the inputlag but we'll see tomorrow.
Also the FPS are with DLSS balanced, wtf
Gonna give it a try without the new driver first.
Too many problems so far with the last couple drivers and my current versions runs fine (572.16).
Haven't played it yet, was waiting for the PT patch.
