Very Sluggish performance in VMWare Fusion
 

I have a 2010 MacBook Pro with 8 GB RAM. Displaylink works fine on the Mac, other than the known issue with iPhoto. I have also installed DisplayLink on a VMWare Fusion VM (Windows 7) and am experiencing extreme sluggishness on the USB displays when I run the VM in fullscreen and set VMWare to use all displays.
