hi friend,

Not sure what is the problem.
Two days ago, I try the IS38 and found when I play the 5 toons, sometime, the fps always drop from 60 to 30 suddently, but after several second it increase to 60 again.
I dont't remember I saw this problem when I lvl up my shaman to 85, I remember it always stay at about 50-60.
But when I reinstall the IS37, the problem still the same.

Any idea what's the problem?

my PC: I5 760, GTX460, 8G RAM
