Even trivially a 4k@120hz monitor is 108x the pixels as a 630x480@30hz monitor and you can clearly render much more complex scenes per pixel. It seems trivial

Even trivially a 4k@120hz monitor is 108x the pixels as a 630x480@30hz monitor and you can clearly render much more complex scenes per pixel. It seems trivial to me to see 100x the speed without relying on benchmarks. That said, speed as a derivative of how long the user waits has not changed simply because humans have not changed what they consider acceptable wait times.
