Vertical sync pulse .

(We will NOT go into the details of my system, because this problem is on two computers) It all started after I reinstalled the OS on my computer and terrible mouse slowdowns began (do not write about the daw in the mouse parameters, hardware acceleration was removed)
like at one point I set it up and it started to slow down less, according to the standard in setting up the firewood, I set it to adapted, the number of pre-prepared frames saved 1 1, or 1 3, by the way, if you put 2 3 in the control panel, then in the css you can see shadows through the haze and see opponents (cheating a little))) More to the point, can you help with this problem (mouse lag, slowdown every few seconds in all games, lines, the image in the game twitches, sometimes pieces of two frames are displayed, or there is a flickering horizontal bar in the middle screen) I would be very grateful.
