Patch definitely made it worse. There was chopping and stuttering in 6.0, but turning sound off and on again would fix it (for me, at least). With the 6.01 patch, sound has turned into complete garbage. As soon as skills start getting used, the audio quality explodes, it sounds like someone running rocks in a blender. Even after combat is done, music and ambient sound is choppy and distorted. Dialogue is broken and unintelligible.
