So I recently bought a new MacBook Pro Retina, 15-inch, Mid 2015 which includes the Radeon R9. I went ahead and installed Windows 10 on a separate partition to play games such as GTA V every once in a while. With that said, it doesn't seem to run that well even when lowering settings. I've tried downloading the latest drivers provided by Radeon (which also seem to be a whole version below the latest they offer for non-mac graphics card). Any ideas for improving performance?
