Problem with Lucidlogix virtu

[Shizora]

Just bought new Hardware (Asrock Extreme v4 z68, 560ti, i52500k). The Mainboard supports Lucidlogix Virtu technologie. That means i connect my graphics card on the mainboard hdmi slot. In idlemode (windows etc.) the gpu from the i5 is used and if I start a game my 560ti is used.
But it doesen't seems to work with CoD. I have very weird texture problems, also in the mainmenu. I can't see menulabels, at least i mouseover them...
