New Z575 crossfireX glitching

Brand new Z575 laptop from newegg.  When crossfire is enabled, and a directx 10/11 game is launched, there are a ton of artifacts and graphical glitches.

 

If I run it in power save mode (using integrated graphics) performance is about 30%, but there are no issues (only using integrated graphics)

If I turn off crossfireX and run in performance mode, performance is about 60%, and there are no issues (only using discrete graphics)

If I turn on crossfireX and run in performance mode, performance is 100%, but seems like every other frame is glitched (using both)

 

How do I fix this?  I would attempt do download the latest drivers off of the lenovo support site, but the link is broken.

Well, I did a system recovery, and everything works fine now.  Must have been some sort of wierd corruption with the driver when it was imaged at the factory.  I didn't do anything different the second time around.

 

Happy now.  Just wish I could do CrossfireX with DirectX 9 games and this would be the perfect laptop.
