archicad, from ver 12 to ver 13

[Anonymous]

two pc's have been moved to version 13, one is working well, the second one show important slowdown while using 3D views.
the two PC's have identical hardware
tried to check all components, exchanged diverse parts, video card, disc, memory etc, the problem still on the same pc.
tried to uninstall version 13 and back

any idea ?

It could be the motherboard if everything else has been swapped? Have you noticed any problems in other programs? As the 3d window is powered by the graphics card, it may be worth downloading a graphics card benchmark and run it on both machines. It may rule out a specific problem with ArchiCAD. Try 3dmark06 for example - http://www.futuremark.com/benchmarks/3dmark06/download/
