When I run games with my new R9 270s MSI Afterburner shows GPU2 Usage % spiking up and down from 0% to about 40% in thin lines. It does recognize the second GPU though, as does the AMD Overdrive software. My FPS sucks and doesn't really change when I enable/disable crossfire. When I run FurMark it says

GPU 1: AMD Radeon R9 200 seried detected GPUs (AMD Crossfire enables, 2 GPUs)
GPU 2: not available

I tried booting to safe mode and running driver cleaning software then reinstalling all drivers, messed about with setting, and tried each card in each pci-e slot to check that they boot up. I am not really sure what else to do

Yes they are running in full screen. Oddly enough, the second GPU is not working for Metro: Last Light, Far Cry 3, or FurMark but I did see some activity in Left 4 Dead 2. I tried that for a few minutes and got activity out of the card, and in AMD Overdrive the second card had a percentage under "activity" which did not show up before.

Thanks a ton, that did it! Why would they have such a stupid feature?
