Hey, I have the early 2011 15" MBP with the hd6750, I have been trying to update my drivers, pretty much since i got it. Today I finially did the delete drivers, driver sweeper, install the drivers (v12.1) from the amd website. However I am still getting it saying I have incompatible graphics hardware or something, you know the message. I am at a loss at what to do because this is what every website has said to do.
