Ok, I solve this problem (by workaround of course).
1st of all, u need to turn off all sync features.
2nd, in NVIDIA panel or desktop change refresh rate to 120. In NVIDIA panel u will need to click on "Ultra hd, hd, sd" (dont click on PC) and choose ur screen resolution (then choose 120hz)
3nd (not important), lock fps to 120 in game.
I tried to lock fps in game previosly, but it didnt work. I just needed to choose lower hz on my monitor. So stupid...
