120hz or 60hz.Whats the difference in most games?

[light001]

So i have a BenQ XL2420t. And i can set my resolution to 60hz or 120hz....thing is, i get weird stuff happen to me in skyrim, because its a 60hz game or 60fps game? So i have to adaptive half refresh rate that game to avoid odd things.
Now i was wondering if the same stuff happens in other games? and if it causes issues ...should i just leave it at 60hz all the time? because i was also told that most people cannot tell the difference from 60 fps to 120fps. Also that 120hz is mainly for 3D? i have yet to get the glass's for 3D. So honestly does anyone have any vast knowledge of this? and why skyrim would bug out in 120 frames, and or hz? and be normal @ 60? and with most other games?....

Like what should i notice in most games at 120fps vs 60fps? 120hz vs 60hz? any comparisons? ideas or thoughts?

You should play with whatever framerate your getting or closer too. If you play with 60FPS on 120Hz you're likely to get screen tearing. The 120Hz really helps for fast paced gaming, but if you can only get 60 or so FPS, it'll cause you more trouble than setting your hz down to 60.

120hz makes games more responsive. Skyrim is an odd case, as they have an internal clock for their game engine that works at 60hz, and not so well above that. I have heard Rage has similar issues, though most of these rare cases have a built in FPS cap.

If you do not use v-sync, 120hz is pretty much always better, even at 60 FPS. Everything is more responsive and tearing is less noticeable. 60 FPS on 60hz has a tear on every refresh, and barely moves. 60 FPS on 120hz has a tear on every other refresh. That means 120hz gives you half as much tearing.

For Skyrim, I'd try to use Adaptive V-sync (half refresh). And leave it at 120hz. Even at 60 FPS, the 120hz setting will give you half the tearing, unless you turn normal V-sync on, which has no tearing, but adds stuttering. Even then, a 120hz monitor with V-sync has less stuttering, but would require a FPS limiter in this case.
