When I start the game in dx 10/11 the screen just goes black but the game launches fine. The music plays, and the in-game cursor appears, and I can hear the click of the main menu buttons being highlighted, but there's no graphics other than the cursor. On DX 9, the game plays fine. I've already verified the cache, I can't think of any other ideas. Anyone else have similar problems?
I'm running a GTX 660, and play other games in DX 10/11 fine.
