FYI MFG is garbage. All it does is add frames you don't need, because the latency it adds is incompatible with fast/twitch competitive gaming and therefore only of value for sightseeing single-player content.
In a single player game, normal 2x framegen at ~120fps feels like a 50fps experience, which is borderline. 120fps is already plenty smooth enough for single player stuff, but the latency hurts it. Getting 240fps with MFG but the game feeling like a 45fps experience is even worse. We don't need more frames, we need less lag.
I was trying Indiana jones with full path tracing on my 5070Ti and leaning heavily into framegen, but suffice to say I turned it off again. Honestly, in single player stuff, being forced to use reflex which disables vsync and VRR is actually a really big loss. Jerky, out-of-sync animations, uneven camera panning, screen-tearing - the general loss of buttery smoothness is a huge immersion-breaker for me. I'd genuinely say that a constant, capped 60Hz vsync is a nicer experience than 120fps framegen, 180fps 3x MFG, or 240fps 4x MFG. The locked 60Hz experience will be smoother, and lower latency, so it'll feel better too. Don't even get me started on framegen artifacts....
