I experienced that interactive rendering on VW9 under Open GL does not work at all - moving the perspeive changes into wireframe mode. under 8.5, it worked very well with QuickDraw 3d interactive.
Even the simplest boxes shade in wireframe only...
Besides the 'viedo card woes' issue, this is another thing that IS frustrating! Does anyone have a solution for the problem (my configuration is VW9, 512 Mb ram, G4 MP533, OS9.1)
