A couple of things off the top of my head you might want to look into.
There was one poster during the tech preview beta period that had an issue with an application running slowly for no apparent reason. One thing he tried was to turn off 3D acceleration and his application then ran much better. That's something to try and to see if it makes any difference.
One other user posted that he was seeing screen flickering and other anomalies. He checked to make sure that the shared graphics in memory setting the VM's Display setting was set to 8192 - the recommended setting.
