I wanted to open a thread no to complain but to discuss specifically about the R9 m295x's drivers in Windows 7/8 via Bootcamp. I've just received my RiMac. I've just installed Windows 8.1 to play some games in Steam. First reflex : uninstall the "Apple" driver of the R9 and install a dowloaded one directly from AMD. It does uninstall well but it does not install the new one. Even the beta drivers from AMD. The process goes all the way till the end but clearly nothing happen and I'm forced to go back with Apple R9 driver if want to use my external monitor. I've read all the graphics thread about the RiMac and I've seen that some of you have encountered this exact problem on their RiMac. Anyone succeeded installing a better driver for the R9 m295x in Windows so far ?
