Hi am having the Mac Pro late 2013, quad core Xeon with AMD D300 model. I am having issue with the AMD Graphic Drivers on the windows 8.1. The Bootcamp 5 installation is so messed up the drivers has to installed manually. After installing the graphic drivers, the screen shrunk its size, the display quality is very low, the games are performing very poor. FirePro control panel doesn't show up and I tried downloading different versions of AMD Catalyst software, nothing seems to work. Can some one help me with this issue?
