My problem basicly is that when I try to import using FBX from Mudbox to Maya, Maya freezes.
My model is a plane with 1,400,000 Poly's(A flat one sided surface not a flying machine haha)
It's of a snow hill area with rocks.
One bump map and one for the texture.

I have Windows 7 64 bit
8 gigs of Ram
Fire GL 8650
Amd Phenom II 965 Black Edition
750 Gig Harddrive

There's no lag at all in Mudbox, it runs amazing smooth.
