I don't know... That's just my experience with online multiplayer games on my old terrible computer where your framerate does not effect your movement speed. Since I had such a low framerate, I would keep skipping my character forward instead of it looking like my game was slowing to a crawl (like some (most?) single player games).
Anyways, there's a driving/racing game called Fuel, that obviously wasn't really fully completed, but was still awesome. It made the mistake of having framerate effect your actual movement speed. So in even the fastest vehicle I could only reach a certain speed until my old computer couldn't keep up and you could actually see the speedometer stop well below the car's actual top speed. (I have both the PC and PS3 version - didn't have framerate issues on the PS3 version, so I was able to reach the cars' real top speed.) Anyways, this made it impossible to keep up with with the other drivers in multiplayer on PC, even in the fastest car, because I couldn't go as fast as them.
