3D views choppy

Thank you both for the reply, but I fail to see why the FIRST laptop I purchased, the one with the separate Nvidia graphics card with 2GB of RAM ALSO failed to produce smooth scrolling in 3D views. The original PC I tried this on was a Toshiba Satellite C655D-S5518. It has a Radeon graphics engine on the motherboard, not a separate video card. The Toshiba specs for that laptop state it has "384MB-1459MB dynamically allocated shared graphics memory". In other words it shares the system RAM. And it functioned flawlessly.
I still think there must be a compatibility issue with the Intel graphics on the motherboard which I currently have.
