1050 ti screen flickering

Since I bought my 1050ti, I am experiencing some issues when playing. The screen flickers and turns on and off very often. When I discovered that unticking the Vsync (in graphic tab), the problem would fix, and I was able to play at 450fps.
Some days ago, when the new patch was released, I can only play it at 60fps, so I am experiencing the problem again. Do you have any idea what could I do in order to play the game normally again?

1050ti gigabyte low profile
