2ms to 5ms difference? lmao, you're telling me you can tell the difference between the two? No human being I heard of can discern 3 ms time frame.
Times add up 3ms here 2ms there. I said the average gamer won't notice but the serious high end gamers will notice a slight difference. If you don't understand, don't believe me, or don't care, its not going to make me lose any sleep.
