I'm running a Thinkpad Ultrabook Helix (Model # 3698-4SU) and the Thinkpad USB 3.0 Dock with 2 1920x1080 monitors connected. I'm seeing mouse lag and high CPU any time something needs to be drawn on the screen. If I resize a Window I can spike all 4 cores on the I7 to 80-90% CPU, at which point the mouse becomes very laggy, and the overall system becomes very slow.

I've updated all drivers/firmware available and set all BIOS / windows power settings to maximum performance. I am running Windows 8.0 with all updates installed.
