Hi have a lenovo ideapad z575. It has a a6 apu and a radeon 6650m graphics card running cross fire. The problem is the graphics are only running off the HD6520g that is built into the apu. The 6650m graphics always runs at 0% even when gaming. I have updated all the drivers and tried disabling the drivers on the 6520g with no better result. If i can some how disable the cross fire and make it so it only runs off the 6650m that would work.
