I'm having the same problem and my post didn't receive any responses. If you watch your CPU usage you can see why the stutter occurs, simply resizing a Window can cause 80-90% CPU usage on an i7 across all cores.
By the way, we got the firmware update to run from a Windows 7 system and it didn't help performance in the slightest.
