Video Card (6670) "throttled" or not in use after waking from sleep?

Hey All,

Just running my first Hackintosh build. Pretty much everything worked out of the box. Setup is as follows (running ML 10.8.1):

CPU: i5-3570K
MB: GA-H61M-DS2 (rev2.2, dual UEFI)
GPU: Gigabyte Radeon 6670 (GE=No)

What I'm noticing is the following:

When I first start the computer and run LuxMark, I get a score of around 225 with the default test. If I put the computer to sleep and run LuxMark again, I get a score of roughly 65 (repeatedly). It will not give me full performance again until I restart the computer.

To me, it seems like it's switched to the onboard video after wake and is not utilizing the card, although that's really just a guess. I'm not even sure if that's technically possible.

Has anyone else come across this before? I can post LuxMark (before and after) logs or other assorted info if need be.

Thanks in advance!
