Texture Flicker with Windows 10 and Crossfire 7950

[Mojo]

Hi all, I recently upgraded my main PC from Windows 8.1 to Windows 10. Almost simultaneously, as luck would have it one of my mates had an RMA replacement 7950 come in that I managed to get on the cheap so thought I would embark on Crossfire 7950s.

However, on installing the second card, updating to the latest drivers and and enabling Crossfire so far I get texture flickering, high GPU usage and crap framerates on virtually everything (35fps on Team Fortress 2 anyone?). I know Windows 10 is relatively new so teething issues with Multi-GPU solutions are to be expected, but has anyone come across similar issues and perchance have a workaround for them with a well placed hack?

'tisn't the end of the world for the second 7950 as if I'm buggered as I can put the second 7950 in my Media centre, but any help would be appreciated!

Flicker ? sounds like vsync issue ?

I've noticed some severe flicker using my gtx780 on win10 when i added HDMI output to a 4k tv, like massive explosion of tearing going up and down the screens; i'm assuming its just teething problems with win10 drivers.

Windows 10 updates drivers by itself silently unless you disable auto updates. Make sure you are actually running 15.7.1 drivers and not some newer beta driver.
