With the recent Nvidia Driver Update "496.49" the game becomes unplayable after couple of minutes. It starts with the mouse cursor by flickering and the game fps is dropping from my 141fps to 50fps then back to 141fps and in the next moment its going down again. I had once this issue some months ago and after Nvidia released an new driver update, the issue was gone. Also after restarting the Pc and going back to the game will fix this issue for couple of minutes before it starts again to drop the fps! Is there anyway to fix this issue permanently?
