I played 1.0 with an Alienware desktop, windows 7, I-7 microprocessor, 5870 AMD graphics card (I keep the driver current). Windows 7 comes loaded with directx 11. Once in a great while, I would get a directx stopped working message, but most of the time, the game ran just fine.

When I attempt to run the benchmark tool, my system won't run it with directx 11. As I understand it, it's dangerous to change the directx version, and directx 11 is supposed to be backwards compatible. In reading some of the benchmark results posts, I noticed that many were able to run this with directx 11.

Would someone be kind enough to explain my options here. Kind regards.
