Why does it happen only on one of the engines here too? Frame-gen is insanely good, but things like this make me not want to use it honestly.
It is getting better too be honest, especially since the latest release by NVIDIA. It’s fully in their hands, it’s not something Asobo can fix.
The camera angle and the individual engine RPMs affect the perceived movement of the fan blades, Frame Gen works by interpolating this movement so the subtle differences this causes between the two engines means that one gets artifacts and the other doesn’t.
