{"ref":null,"ref_type":"repository","master_branch":"master","description":"A bootleg fix for Mac Pro users who are running Bootcamp with their Dual AMD FirePro D300 + D500 GPUs. Many users have been reporting poor optimization and support with current games. Obviously, the FirePro GPUs are weighted more in heavy-lifting with applications rather than gaming. However, with some magical modification magic: anything is possible.  I found from my own experiences that most games were only recognizing one of two of my GPUs (i.e. absolutely no real CrossfireX support.) Even the single GPU that it WAS using was not running to it’s maximum capacity with the provided Bootcamp drivers from both AMD and Apple.   Using the current update drivers for most AMD GPUs, I modified a fix that should bring the D300 + D500s to 2015. Installing this update should bring you to Radeon Crimson v15.12. I went from running at 1920x1080 @ Low-Medium settings with no AA at 60fps to running 1920x2080 @ Ultra/Max EVERYTHING [including the highest AA setting] @ 60fps for most games (tested on GTA V and Battlefront mostly).  Here are the caveats: 1) It’s obviously not vanilla and won’t be until AMD + Apple get moving with their own updated drivers for their Mac Pro line….don’t count on it.  2) You’re going to have to enable test-signing + test mode PERMANENTLY on your Windows OS, or at least until AMD releases their own drivers with signatures [but don’t worry I wrote a batch script that does all that ‘test mode’ lifting for you]  3) You’ll have to clean out all existing GPU drivers (including your Bootcamp AMD drivers) using the Guru3d uninstaller that it’s included [or this link for the most updated version: http://www.guru3d.com/files-details/display-driver-uninstaller-download.html]  If you happen to fuck up anywhere along the way and decide that it isn’t working out for you: just use the Guru3d driver uninstaller + install the original Bootcamp drivers!  Ok! Enjoy!  WARNING/DISLAIMER: This whole bootleg modification is probably frowned upon by AMD. I hold no responsible for any issues/damage with your system.","pusher_type":"user"}
