Well, I eventually got the latest Catalyst Beta to work with my nMP (6-core, D500s) and, WOW, GTAV at 1440p, very-high-everything settings is INCREDIBLE. An absolutely flawless crossfire implementation. 60FPS, solid, no stutter.
Here's how (I think) I did it:
- remove all drivers with DDU;
- unpack Catalyst Omega drivers;
- unpack latest Beta drivers;
- unpack December 2014 Bootcamp drivers;
- replace the entire contents of the Bin64 subdirectory in the Beta drivers' directory (in c:\AMD\) with the entire contents of the Bin64 subdirectory of the Omega drivers;
- replace the Installmanagerapp.exe and installmanager.dll files in the Bin64 directory of the Beta drivers with the same files from the Bin64 directory of the December 2014 bootcamp drivers;
-run setup.exe in the beta drivers unpacked directory.
I lost my catalyst control panel in the process (despite registry cleaning) but, who cares about that if crossfire no longer needs to be switched off for GTAV???
Good luck!
[EDIT: I managed to get the Catalyst Control Panel working by re-running setup.exe in the 15.4 Beta driver unpacked directory and making sure the tick box for the installation of the control panel was ticked (after selecting a "custom" install).]
Doesn't work for me.
It doesn't detect the driver in the installer, just installs the CIM and one or two other packages, no driver and no hdmi audio etc.
What version of windows are you running? I'm on 10, latest build.
This is all it allows to install, which doesn't include the actual driver.

This method doesn't seem to work on the 15.7 drivers - the install will only add the Catalyst/Firepro Control Center, and not the driver or other package content.
I was able to use the method to install up to 15.6, any tips for 15.7?
It's been a while - last time I tried was back in July, but I did follow the instructions to the letter multiple times and produced the same result. I can't remember when exactly, but Apple rolled out new official drivers over Bootcamp, and I stuck with those in the end.I am pretty sure you didn't follow the instructions accurately.
I've managed to get the latest Crimson drivers working on the nMP. Basically followed the previous instructions

Of course it could have been that (and a couple of subsequent) builds of Windows 10 that caused the issue, there have been quite a few since July, I temporarily dropped out of Windows Insider builds as I needed a little more stability, now the option to get back in is blocked by a message saying 'some settings are administrated by your company' or something (which is me), and I haven't been bothered to ix it yet.
At the time Crimson wasn't released, I'd be interested to try that - let me know if you get it to work!
Which nMP model do you have? I have Quad core with upgrade to dual D500, 16GB RAM, and 512PCI-E, I don't think I get as high fps as you though on 1080p, so maybe I should look into the catalyst drivers again.
Currently running an IPS 4k Panel, sadly I can't get more than about 9fps out of GTA V at native 4k though!!
This is why the OP was so wonderful
Thank you!

As of a few weeks ago AMD released genuine Crimson Drivers for Macs. I removed all my DIY works (as per this thread) and installed the new drivers for my new Mac Pro from AMD and everything has been great. Be very careful to uninstall all AMD drivers and reboot before running new install! I use a 3rd party utility that's free called Display Drivers Uninstaller a.k.a. DDU. As with all things for the Windows environment I down load on the Mac and unzip there. Then transfer to Windows one way or another (Thumb drive or directly from the Finder using Paragon NTFS). That way you avoid the crapware and dirty tricks that abound in the Windows World.
Since installing the genuine drivers from AMD I have a cooler Mac too! Remember Catalyst dual GPU system requires full screen, it doesn't work in a windowed game.
I'm getting fast frame rates at 2560 x 1440 with very high graphics settings in GTA V, Just Cause 3 and my Mac Pro aced the Steam VR tools app with well over 120 f.p.s. in the test, something it could never do with the DIY hacks in this thread.
I still only run Windows 10 (or 8.1) by booting directly into an external SSD or SDHD from the new Mac Pro, never using a partitioned Boot Camp set up on the internal. You need an ISO in the VM of the version of Windows you are going to install. These are easily made with two free tools running in Parallels or VMWare Fusion, WintoUSB, and to partition the disk correctly prior to using WintoUSB, I use the free Mini Tool Partition. This easily sets up your drive for the small EFI Fat32 area (200 MB is more than enough) and the rest as NTFS. Remember to convert the disk to MBR and set the partition EFI to active. This is all obviously done connected via USB3 but once done the working Windows drive can be selected and booted from a Thunderbolt dock or USB3 dock (hold option at boot on Mac to select EFI volume).
