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


Mar 30, 2010
Dear all,

I have just got 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 screen blacks out for 1-2 seconds before it performs the task.

My laptop’s 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 don’t know what is the main problem either should they offer to change anything.

It will be great to get your view on this, thank you ahead! ;)
