When I go back to the desktop after gaming and start cgminer, I get really low hash rates in the single digits (usually get well over 350k for scrypt). If I reboot, all returns to normal. Of course its a pain to have to reboot to switch from gaming to mining, so I'd rather not have to do this. Seems like the video card is not being restored after the games are shut down. I tried the GPU restart in cgminer, but it didn't help. Anyone know what might be causing the issue or have this happen?

Here are system details:
