Well Today I upgraded my GPU to a XFX Radeon HD 7950. After downloading the latest drivers from ATI I found that when I attempted to launch BF3 I got an error saying "failed creating d3d device of at least version 10.0 on adapter amd radeon"
I could ran it before and I had a worse card, it was a Zotac Nvidia GTX480.
I'm runing on win 7 x64 but as I stated before I COULD run the game before changing mi GPU to a better one.
What could be going on?
Update: I already installed the latest Microsoft Network updates and all the system updates and still the same.
