New Dell Studio XPS 1645, but lags in Rhino 3d Modelling

Posted: March 31, 2010
Dear 3D Gurus,

I have just received my Dell Studio XPS 1645 (Intel Core i7 720QM 500GB/4GB), but it is slow when I rotate/ move/ orbit my model in Rhino 3d. The other viewports will black out for 1-2 seconds before it performs the task.

My laptopís specs are:

Installed Video Memory: 1 GB
Video Chipset: ATI Radeon HD 4670
Hard Drive Capacity: 500 GB
Operating System: Microsoft Windows 7 Home Premium (64 bit)
Processor Speed: 1600

Are there anything I could upgrade to avoid this glitch?

I would like to contact DELL on this matter, but I donít know what is the main problem either should they offer to change anything. It will be great to get expertís opinions on this, thank you ahead! Smile
