full screen preview, performance degradation

[cc15124]

When using Full Screen Preview, I am experiencing a slow down of streaming audio and jerky video response. I suspect this is a video adapter issue but would like to confirm. PC is as: OS- Windows 7 HomePremium 64, 16 GB RAM, Intel core i7, 3.4 GHz. Video adapter(s)- Nvidia Quadro 450 and Quadro 290..............not high end video adapters, but needed 6 monitor capability. I only use desktop switching on my primary monitor, 5 others are static.

nifty configuration.
It should run the Full-screen preview without any slowdowns in general.
