DirectX is version 11. I tried setting the game and the video card to the minimum settings, but it didn't help. I also tried inserting the memory modules one at a time, but that didn't help either. Now I've removed the video card and tried running it on the integrated GeForce nvideo 5500 card (I think that's what it's called), but it still doesn't help.
