35-40fps is more than playable, stop being a moron.
For racing, rpgs, adventure, and rts games,
maybe. FPS? No.
You're so arrogant. 40fps is playable considering that the human eye can only process 60.
derf derf human eye doesn't process at frames per second, we can simply not differentiate between speeds over around 60. Some can see a difference between 60 and 70, some can't see a difference between 40 and 50. And by your own logic, 40 fps is 20 fps lower than 60 fps, making it not smooth and therefore undesirable.
30+ fps means playable.
Damn, blocklanders have low standards. Godforsaken low standards. I don't know how you live.
