WoW is an immensely popular game of course and after Lion, I encountered a strange situation. Powered on my iMac and once all of the background services were running, I proceeded to play WoW except it was extremely sluggish. I fired it up on my Snow Leopard Mac and it ran fine. I rebooted again and WoW now ran just fine on Lion. I have the high end video card with 256MB RAM and never have performance issues. I checked the CPU/Memory/Disk Utilization performance monitors and they were all nominal while the game just stuttered along. Has anyone else experienced this type of behavior?
