Strange quirk I'm having with vertminer -- and it probably has nothing to do with CGwatcher, but maybe someone here has an idea. I have a rig running 3 7970s, and use CGWatcher's "Devices" tab to disable GPU 0 when I feel like playing a game. When I finish a game and re-enable the GPU, it hashes at like 15-20kh/s instead of the usual 360+. I've tried stopping and starting vertminer, quitting CGwatcher completely and restarting it, and disabling/re-enabling the GPU again. The only thing that remedies the problem is rebooting. A minor inconvenience, but I'm curious if anyone else has had this issue.

This is a graphic driver issue, that happens to me only on 280x but not on 270x cards when the video driver crashes and restarts itself (the one that gives the message that the driver stopped working and has recovered), when the driver is restored the 280x have very low hashrate even though the clocks are ok etc etc...
