I tried Catalyst 12.2, 12.3 and 12.4 in each case the CCC puts the E-450 APU to full speed even when maximize battery life is selected. I test this using brazos tweaker and furmark(by the fps counts)
If I re-install the driver, the GPU speed obeys the power manager settings of windows (amd battery saving/performance settings appear in windows power plan also). If I start CCC, the speed gets stuck at full.speed. The only way to get it down is to kill CCC or re-install driver.
Why CC does this?
