Slow navigation with new laptop...


New member
I've just bought laptop from Dell:

Dell Studio 15
Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz
4,00 GB RAM 800 MHz
ATI Mobility Radeon HD 4570, 512 MB
64-bit system
Resolution 1920x1080
DirectX 10

Rhino 4.0 runs pretty slow even when starting a new document. It runs faster on my last laptop (Acer Aspire 4715z) with no dedicated graphic at all. Is it perhaps because of the 64-bit system or why can it be?
