30 vs 60 fps - can you really see the difference?

It's pretty obvious in that video - almost surprisingly obvious, since I've often heard the claim that stable 30 FPS should be pretty much equal to stable 60 FPS. I didn't fully buy it, but I thought it might make the difference considerably less noticeable.

Also, high framerate is not just about the graphics. It's even more about how smooth the game feels. Often, games don't just render at a certain framerate, they also play at the same framerate. With 60 FPS, that's about 17 ms per frame. With 30 FPS, it's about 33 ms per frame. 30 FPS adds a noticeable amount of input lag. In fact, in some games even 60 FPS is sub-optimal.
