So, I want to install the latest AMD Drivers for my 6770m graphics. The thing is, one time I followed the instructions to do that and it actually hurt my graphics performance. What I did was followed someones instructions to install an earlier driver and then install the latest driver. It actually took games that were running at 30 FPS down to 4 or 5 FPS. I had to load a system restore point. Has anyone had luck installing the AMD drivers on their late 2011 15 in Macbook Pro? If so, how did you do it? Which driver version numbers are you using? My specific model is MD322LL/A.
