Can someone explain the FPS on this game

[Krozjin]

Yeah I've noticed weird FPS things as well. The big one I've seen is despite seeing it say 30-45 FPS for me, the game doesn't seem to be completely smooth. Sort of like there's micro freezes between every frame or something. But for that framerate it seems like it should be smoother. Basically it feels like 20-25 FPS vs the 30-45 it displays. So it could just be reading the FPS wrong, who knows.

I know the benchmark is not a true reflection on the game I should be, according to that, averaging around 103 FPS.
