I've just installed the new drivers "Radeon Software Crimson ReLive Edition"
Now when I play WoW, it'll scale down to 500 mhz clock instead of the 1100 mhz clock I use the overclock profile on, even under full load.
it's totally iratic and ruins my gaming experience... the memory clock does overclock properly to 1450. Checked on GPUZ it tells the same story, 500mhz is my default clock in 2d because I'm running 75hz screen.
my graphics card is a 7950:
