DirectX 11 messed up my game

[kanubaba]

I got a virus in my native module of Warband  . So being the experimenter i deleted warband and reinstalled it like i was told to do by one of the tech support guys. Everything was working fine until about 3 weeks ago i upgraded my DirectX 10.1 to DirectX 11 (i have windows vista 32 bit home premium). All my modules work but for some reason they are all really slow, the average fps is around 12.3 fps rather than being the normal 60-75 fps. The same thing happened for the original mount and blade v 1.011. It is also working around 12.4 fps or something around that much.
What should i do, is there a way to reinstall DirectX 10.1.
I really wanna play M&B

I just did a quick google search for direct x rollback, and got lots of conversations on various forums where the question was asked . Most replies said it wasn't possible, and one or two said it was possible but would be a lot of hassle, and suggested instead to try reinstalling the latest direct x in case it hadn't updated properly. I think direct x is supposed to be backwards compatible, though whether that is the case with every version I am not sure.

Thanks a lot for investigating my problem. I'm going to try to reinstall directx 11 again
