Hi, I read that the latest AMD GPU drivers include optimisations for GTA V so I wanted to try installing them on my Retina 5K with a M295X GPU. A couple of months ago I had tried without success but I figured now that the M295X was available in other machines something may have changed. I really didn't want to mess about with editing .INF files or copying old versions of installers over as you may have seen in previous posts about the subject. I am running Windows 8.1 (64 bit). My previous drivers were AMD's official Bootcamp drivers dated 16/12/14. Found here:- http://support.amd.com/en-us/download/desktop/bootcamp And this is what they looked like:- So I tried to download the updated drivers dated 13/4/15 directly from within CCC. It was a non starter, CCC appeared to freeze. I went direct to AMD's download page here:- http://support.amd.com/en-us/download/desktop?os=Windows+8.1+-+64 I selected the Win 8.1 64 bit drivers and downloaded them. I did not uninstall the previous drivers. I ran the executable which unpacked the file. I let them unpack to the default folder and navigated to C:\AMD\AMD-Catalyst-15.4Beta-64Bit-Win8.1-Apr9\Packages\Drivers\Display\WB6A_INF and ran CU182335.exe Everything installed no problem and I have not noticed any specific issues. I can alter the resolution on my display (no 5K). I quickly ran 3DMark across them and did not see any particular performance enhancement that couldn't be written off to 'margin of error'. And here are the new drivers:- I hope it helps somebody else out.
