Wow! Ok, ok so interpolation = motion blur. Heres an awesome article on what yous have pointed out. This is quite the revelation for me and I appreciate the info!

Read the whole article though, its some pretty good info.
Conclusion
We as humans have a very advanced visual system. While some animals out there have sharper vision, there is usually something given up with it (for eagles there is color, for owls it is the inability to move the eye in its socket). We can see in millions of colors (women can see up to 30% more colors than men, so if a woman doesn't think your outfit matches, she is probably right, go change), we have highly movable eyes, and we can perceive up to and over 60 fps. We have the ability to focus as close as an inch, and as far as infinity, and the time it takes to change focus is faster than the fastest, most expensive auto-focusing camera out there. We have a field of view that encompasses almost 170 degrees of sight, and about 30 degrees of fine focus. We receive information constantly and are able to decode it very quickly.
So what is the answer to how many frames per second should we be looking for? Anything over 60 fps is adequate, 72 fps is maximal (anything over that would be overkill). Framerates cannot drop though from that 72 fps, or we will start to see a degradation in the smoothness of the game. Don't get me wrong, it is not bad to play a game at 30 fps, it is fine, but to get the illusion of reality, you really need a frame rate of 72 fps. What this does is saturate the pipeline from your eyes to your visual cortex, just as reality does. As visual quality increases, it really becomes more important to keep frame rates high so we can get the most immersive feel possible. While we still may be several years away from photographic quality in 3D accelerators, it is important to keep the speed up there.
Looks like 3dfx isn't so full of it.
