64-bit for VISTA version and optimization for Core2 Duo processor. And better support for
ATI Radeon 2900XT.

Hm...

I have same problem like some of u. I have Intel C2D 2,6Ghz, 4Gb of memory and ATI Radeon 2900xt and 64-bit VISTA. And Sketchup work so slooooow that I think P1 is faster and not this super computer. I even disabled hardware acceleration and work only on CPU.

Will be there 64-bit version and any new version which will be optimized for good graphic cards?

Milos
