Macpro / Windows 10 ATI Driver issue

Wondering if anyone here has found a work around. Can't seem to find any info online. Attempting to boot camp a Macpro (Late 2013) with the latest Win10 build to run some tests.

Install goes fine, most drivers install fine, but the ATI display drivers refuse to install. I have tried both drivers from the ATI website and Apple's latest boot camp (5.1.5640). Keep getting errors about the driver being compatible with the hardware and it's reverting back to the basic MS driver.

Anyone run into this/know of a fix?

Known issue. AFAIK, waiting for Apple to update the drivers (should happen fairly soon after Windows 10 official release) is the only option for getting GPU acceleration at this time. Some developers were working on hacking together a custom INI for ATI's official driver, but I don't think anything came of it. The FirePro D-series used in the Mac Pro is pretty unique:

Please post back if you find a solution or custom driver.
