Hello,

Having the same issue here.

Windows 7 RTM
Intel DP45SG Motherboard
4GB Crucial (Micron) Memory
ATI 4870 Video (Single Card)

All latest updates and drivers to date.
DisplayLink 5.2RC (5.2.21123)

Once I install DisplayLink 5.2RC, 3D performance on my main display degrades to an unplayable state. (Nothing displayed on the second display except a desktop extension, which shows wallpaper.)

If the DisplayLink 5.2RC drivers are removed, performance returns to previous benchmarks.

Game used during this test was Rockstar Games Grand Theft Auto IV (It also has a benchmark mode, wherein I get approximately 50fps @ 1680x1050 with the DisplayLink drivers uninstalled, and around 3 or 4 with the DisplayLink drivers installed.)

Note that the game is being displayed on my normal DVI video output from the ATI 4870 card, and no motion is being displayed on the device connected via DisplayLink. (MIMO 710S)
