Graphic glitches during the game

I got some special effects, screenshots included.

And the screenshots go on.

And no spoilertags here ..... so I add my dxdiag.txt as an attachement.

Have you tired the latest 11.2 drivers?

For my gfx, 10.2 is the lastest driver (legacy one) which was installed when the glitches appeared.

Those kinds of graphical issues are a common symptom of a video card that's overheating or has been damaged.
