Problem with vertical sinkhronizatsii (Red Dead Redemption 2)

I can't really even include. On all settings activating this option will set the fps at exactly 1 frame at once, even in the menu. And without it, can't play, the lines on the screen so annoying.

In addition, every time after exiting the menu the game and return to the settings my setting frame rate of 120 Hertz jumps to 48. (But sometimes I see the fps more than 50)
