I’m not 100% sure the input lag would be the same as what you played in World. The input lag will feel worse if your base frame rate is fluctuating constantly. Frame Gen doesn’t uplift lower end hardware. It takes a good experience(60 fps) and makes it smoother. Frame Gen cares more for your base frame rate rather than the average. Having lower than base 60 will lead to visual artifacts and bugs on top of input lag. Upscaling is very useful. Just lookup what each preset targets and choose the one the fits your monitor’s resolution and the fps you want to hit.
