OK, win7 and nVidia 600
Is it correct, that the 600 is a more or less smaller graphic ard, but should do its job anyway.
What settings have You set in Solid Edge options for the Graphics?
before changing check the Applications Graphic setting, wether the Quadro 600 is fully dedicated to Solid Edge.
You said this is a notebook, and normally they have an onboard graphic too.
Maybe here is a difference which one should be used.
