The screen flickers in the x64 version. (Euro Truck Simulator 2)

Screen flickers in x64 version and only in full screen mode. Frequently Monica and Vert. I tried syncronization. No, this is not overheating of the vidyuhi, this is only observed in ETS2 and tanks (WOT). In the tanks, everything was decided by the compatibility parameters, and in Ets2 there are some strange shortcuts, they do not want to launch a campaign in compatibility. (I found a video similar to my problem) With firewood, everything is also in order, for example, The Witcher 3, TES5, fallout 4 are going fine. Config of the computer in the profile. I'm already ready to believe that my power supply is dying, but in such a hard game as the Witcher 3, everything is fine to mean it is clearly not iron.
