Hmm. Does it affect your main monitor too?

the flicker usually is first only seen on the left and right monitor but after quitting the 3D application it will also be present on the main monitor.
The flickering can be solved immediately by uninstalling MSI afterburner (but then I loose the ability to overclock the GPUs and enforce both GPUs to be used in the 3D application - without MSI AB, no gaming on the nMP.
I had the computer perfectly stable and at proper framerates with stable crossfire with the latest official bootcamp drivers. I then installed one of your drivers at the end of august which ran beautitul and provided a boost in performance.
Then I tried to install your 17.9.2 and everrything fell apart :-(
I am at a comlpete loss what causes this and I would not know exactly which receipe of driver and tweaks would bring me back the stable running machine.
That I am completely fed up with AMD products is an understatement - very frustrating. This will also be my very last attempt of double utilyzing the workstation for gaming. I will be building an NVidia based machine for the simulator up next although that was the very last thing on my list to go back and twiddle with Windows PCs. I am pretty angry at Apple / AMD for this abysmal product the nMP with a complete lack of basic product upkeep and driver support. It will be my last MacPro for that experience (the old MPs were simply so much better machines with long product life and upgradability).
I will give this another try tomorrow, cleaning and reinstalling diverse driver combinations, starting with the last bootcamp drivers and trying to trace the same upgrade path I did over last thelast year.
I wish Steve Jobs was still around. The new Apple sucks.

If you find a good working older driver version, stick with it until you can test further releases in the future that you find working just as well.

Hey Mat, I have now finally found a solution to get your 17.9.2 to install and work in 3D applications (it was not easy with the combination of monitors involved and MSI AB, crossfire, eyefinity and gaming profiles to play nice with each other - hence the endless frustration after several days of experimenting).
I wanted to share quickly what I have done to get it to work in 3D application (in GPU low power mode it doesn't work well as all screens suffer from flickering once the GPUs wind down to low power mode clock speeds).
1) uninstall MSI Afterburner 2) uninstall any remnants from AMD with the latest DDU version in safe mode 3) reboot 4) verify in device manager that GPU drivers have been removed 5) check for any potential leftover folders AMD likes to unpack / install driver packages (normally DDU will pick those up though) 6) run SFC from command prompt (as admin) (this is only a precaution and part of and AMD trouble shoot about ERROR 1603) 7) install 17.9.2 from your package according to your installation (in my case the only way to get the standard RadeonPro Software to work was to run the Settings fix from the package or install it manually "over" the driver install) 8) reboot 9) create eyefinity setup (quick setup worked fine in my case without the need of reconfiguring monitor sequence) - BE AWARE: with these drivers there is no support for bezel compensation setup, custom resolutions or alike, just the bare bones eyefinity setup) 9) install MSI Afterburner 10) activate the ULPS block and extended overclocking features from MSI AB settings 11) reboot
Now the low power GPU mode flickering will start with these later Relive drivers (and I have found zero working method to reliably get rid of the flickering in 2D mode)
I tried MSI AB in endless combinations of settings, different AMD driver revisions starting from sub v16 up to the latest 17.9.2, tried Clockblocker, tried enforced higher clock speeds in 2D mode in MSI AB, tried Windows power saving profile settings, … all to no avail - the flickering is here to stay.
The Good: - much improved performance in Assetto Corsa (my main simulator) - fully working Crossfire mode and much improved performance in Project Cars 2
The Bad: - no Eyefinity bezel correction available in any way (if your 3D application doesn't provide bezel correction functionality, … tough luck) - no custom eyefinity resolutions - it is either monitor native resolution or no eyefinity (if you are struggling for performance in a certain 3D application, you are out of luck) - "advanced settings" tab in the Crimson RadeonPro Software does not work and the CCC.exe in the installed driver software can also not be started manually
The Ugly: - the moment you are leaving a 3D application all three screens are flickering … period
Luckily I use this Windows installation on the Mac Pro exclusively for running a racing simulator and don't do anything outside of that in Windows. I may be able to live with that until AMD fixes the flickering issues with their ReLive drivers or until I dump the Mac Pro and start using a Nvidia based single GPU system (I am so tired of all the troubles with AMD or multi GPU setup support in general - can't believe I am doing this to myself already for three years).
The Options: - a hack of using the last issued Apple bootcamp AMD drivers (ancient revision, coming only with FirePro Control center with limited capability - no Eyefinity for starters - thanks Apple / AMD
Mat, if you ever stumble over a solution to the AMD ReLive driver flicker issue (apparently I am not the only one suffering from it) and a fix to reenable full Eyefinity support, please share this fix with your driver package and highlight it in the release notes / comments - many AMD users are desperate for this.
It seems that single GPU, single monitor use of Apple computers with AMD GPUs is much less troublesome :-(

Thank you for all you are doing. It is amazing job and Apple should be ashamed - they should really do that job as soon as they are supporting bootcamp.
May I ask you please, are going to release 17.9.3 drivers? I don't know if there are many TW Warhammer II players on this forum, but AMD released this version with tweaks for Warhammer II release and without it the perfomance is very poor. Have a nice weekend!
