I was really excited, when i first saw the realtime ambient occlusion effect in Creo. It's a nice looking effect and can really help to see details in front view.
But when i activated it for the first time, i was very disappointed. The behavior is really strange. Sometimes the effect disappears completely, sometimes only at some places and even more annoying: the size of the effect changes with the zoom level in the viewport. When you are far away the image looks completely smeared and when you are close, the effect gets so small, that it is hard to even notice (see attached pdf).
In my opinion this cannot be the desired appearance of the effect, AO should be only depended of the size of the geometry, but not of the size the geometry is displayed in the viewport.
Can anyone confirm this behavior? What do you think is the correct behavior? Or is it a GPU/OPENGL/Driver related problem?
My system:
Windows 7 prof. 64bit
HP z420 E5-1620
Nvidia K4000 (368.86)
