Graphics problem

Hi all,

I have a Windows 7 based machine  Intel Core i7, 12 gig or ram and a NVIDIA Quadro fx3800

System Manufacturer:Other (not a known system vendor)
System Model:Other
Card Manufacturer:NVIDIA
Card Model:Quadro FX 3800
Your Current Driver:8.17.11.9790
Diagnostic Results: Your graphics card is supported and the driver is up to date.


The problem im having is when rotating models the computer struggles to regenerate the next step and it leaves a ghost of the last view. All drivers are upto date, does anyone know how I can fix this? I have also turned down all the graphics settings to lowest in solidworks (2011) and currently using real view settings too.

Cheers
