I still get the delayed stuttering. after about an hour or two the games becomes unbarable to play from all the HDD thrashing. Toning down the graphics doesn't seem to help really all that much and tbh I can only take so much of degraded graphics before it takes away from the experience.
Ya the memory leak is still there. Happens after zoning multiple times. I just log off and on and that usually fixes it for me. But i do find the memory leak fairly unacceptable.
