It's quite an interesting topicIf you monitor/TV is 60 Hz, it shows 60 frames per a second.This means a frame is on for 1/60 s, which is ~17 msFor 30 fps a frame is on for 1/30 s, which is ~34 msFor 120 fps a frame is on for 1/120 s, which is ~8 msSo the latency basically halves going from 30 fps to 60 fps to 120 fpsWhich is why increasing the frame make the game much smootherAlso there is also the monitor/TVs response time to take into accountYour average monitors/TV would add another 5-10 ms, a gaming monitor would be about 1 ms.Was the difference is much more noticeable in first person shooters, where slow reactions get you killedhttp://30vs60.com/http://boallen.com/fps-compare.htmlhttp://gfycat.com/MerrySpiritedBasshttp://gfycat.com/OblongTautDragonfly
