Windows 8, Lenvo USB 3.0 dock = lag + fuzzy image

After some playing around, including the pre-release driver Wim posted and doing the crazy USB 3.0 driver hack, the mouse lag problem is almost gone for me. I think it's close enough that I'll be able to look past it while we wait for a rock solid driver. If no docking were like running a game at a constant 60 frames per second, it now feels like 60 FPS with an occasional dip to 50 FPS. Not terribly significant, but it's there.

You know what the biggest difference has been? As mentioned by Wim, changing the power mode to High Performance. It's strange, though, because my Balanced profile has everything set on the highest performance settings when plugged in. The High Performance profile must do other stuff under the hood that can't be controlled with the UI. When I switch to Balanced, the mouse will skip around when moving over Outlook. In High Performance, it's pretty much as smooth as when not docked. Weird, but I can handle having to switch when docked. Obviously it's not ideal, but it works.

Give it a shot and post your results.

Dell XPS 12
Targus USB 3.0 dual video dock with power
Two Samsung 24" monitors going over DVI (one of which converts from HDMI coming out of the dock)
Back to original Microsoft USB 3.0 eXtensible driver
Latest Intel HD Graphics 4000 driver from Intel
Wim's pre-release DisplayLink driver for the dock
Windows 8 64-bit
