I am a bit slow you guys probably know this, but had problem running OclHashcat-plus on windows complained about drivers not being 12.8. Even if I uninstall all AMD soft and run Atiman + Cleensveeper did not fix this but Driver Fusion I REALLY recommend this program even if there are some bugs

Uninstall all AMD software reboot, run Driver Fusion select AMD remove all, check Driver Fusion again so all is gone

install new AMD driver

sorry if this is well known

Cg Miner runs really smooth now whit clean driver
