I guess everyone has there preference. Personally, I don't think I have ever been bothered by 30 fps. On the other hand, I have been bothered by 60 fps. I forgot what pc game it was, but I actually limited the fps to 30 because 60 fps just looked and felt weird; like the game was in fast forward and it kinda made me dizzy. I think that maybe 120 fps would be better because that's closer to our perception limit, but for some reason 60 fps just doesn't work very well for me.
I have played many FPS games, and I honestly can't say that 60 fps makes the experience any better. Personally, I'd prefer if 60 fps was sacrificed to accommodate a higher resolution and just better overall graphics.
