Funny the game crashes which causes you to download the entire game again if it wasn't fully complete.

Looking at the processes running from the cmd line my guess is it's the Coherent UI causing the slow down in performance. I can see the Coherent UI runs as a separate process from the game, if its a transparent window composited on top of a OpenGL context you will be hitting the window server compositing path on every frame. This is the same problem WOW has on the Mac, the ad-ware for Blizzard runs on a separate window under the fullscreen display. Everytime the ad-ware gets updated it hits the compositor path which is a huge slow down... it's about every 5-7 frame for WOW. The performance hit is enormous.
