If by flickering you mean tearing then yes. Limiting your FPS to 120 does not remove tearing. You will either get a fixed location tear if exactly 120fps can be maintained, or more likely a slow moving tear as the fps fluctuates ever so slightly around 120.

Yes tearing screen, in places when i have 120fps (capped the fps on 120fps) when i move the mouse i can see tearing. Could my 120hz screen is broken i dunno... ?!

I think 120Hz is broken...

For example in BF3 if i use fps cap to 120fps and 100Hz i get minor tearings, but if i put 120Hz and 120fps cap, i get only one tearing on the screen, but it's a big one....

If i use 144Hz and 120fps cap i get same as 100Hz.

Hmm strange thing.

1.If i select 120Hz then i cap the fps at 120fps, while moving i get only ONE tear on the screen the rest is smooth
2.If i select 144Hz and i cap the fps at 120fps while moving i get SMALL MULTIPLE tearings on the screen
3.If i select 144Hz and i cap the fps at 144fps i get the same as number 1 !


So seems that the number of Hz + the exact number of fps at the Hz causes one big tearing on the screen....

I need to play on 144Hz and fps cap to 120fps to get small tearings and to not be noticeable....

You must be sensitive to tearing like I am --
To eliminate tearing you need VSYNC ON. It adds more input lag, but eliminates tearing.

A good compromise is simply to uncap your framerate, and then use Adaptive VSYNC. That way, you have no tearing whenever you framerate runs very high, and tearing only appears when framerates slow down.

Well as i said before if i cap the fps at the same Hz and that fps reaches ex:120fps on 120Hz then when i move i get only one big tearing on the screen the rest is smooth, but if i don't cap the fps or i have lower fps than the selected Hz, ex: 120fps on 144Hz i get small tearings on the screen but it's more better. It's even more better in terms of flickering compared a 120hz monitor to a 60hz monitor.

That's normal, no matter what display you have.
Stationary tearlines always happen when you cap framerate near Hz when VSYNC OFF.

If you hate tearing, then:
-- Use VSYNC ON (eliminate tearing completely)
-- Or use Adaptive VSYNC. (uncap framerate, set game to VSYNC OFF, set nVidia Control Panel to Adaptive)

And then make sure your games run at high framerates for the best experience in either of the above situation.
