there where already many threads about that topic which came to similar ideas. When in fact the only thing that influences the "smoothness" factor is the difference between max/min fps, then there is a easy fix for the intel system -> limit max. fps or enable vsync.
If that hypothesis would turn out to be true, a intel rig would be sometimes even more smoother cause of the often higher min fps rate then a amd rig or the other way riudn if the amd rig has a higher min fps and the max fps is limited.
Imho its the "smoothness" debate is the same thing as the "they eye cant see more then 30fps" debate. It is based to much on the individual to make a general statment, just like people say they can see the difference between 60fps and 100fps. Maybe some individual can but the majority can't, its the same with audiophiles, play joeavarage a 192kbit/s encoded mp3 and a flac file on a highend headphones, they won't notice the difference, hell maybe they would even say the mp3 sounded better.
well just like said above, there are often cases where the min fps is higher on the intel rig -> enable vsync, limit max. fps and you have the same smoothness as the amd rig, but your artificially limiting your gfx card of showing what power it has.
