Hey, I recently upgraded to a radeon hd 6670r 2gb. I just bought battlefield 3 today, and it said that I need to upgrade my graphics drivers. I upgraded them. Three times to be exact! On the third time I looked into the logs and saw that it was upgrading the 4250 instead of my 6670. The 4250 is my old card. I need to find a way to get rid of the 4250, I think it is integrated. Any help I could get is nice, co-op isnt working well :P.

The best way to verify is to check in the device manager the current drivers of the display adapters. You should see the one for the 6670.
Are you connecting the monitor directly to your graphics card and not the monitor?
