Used to have a gtx 295 and then upgraded to a 480. Had the demo for Empire Total War back when I had the 295 in my pc and it worked fine then. I have only just recently bought Empire though (played Shogun 2 and LOVED it) and now I have this annoying problem.
So yeah, at first I though it might be a gpu problem aswell (something up with the 400 series maybe) but if others are not having this problem then it has to be something else.
My specs are,
Windows vista 64-bit ultimate, i7 920 for the cpu, get 480 for gpu and 6 gbs of ram. Motherboard is Asus pt6 delux v2.
Glad to know I'm not the only, one and would love to have to problem solved aswell so thanks for your reply.
