I do not know what causes the slow down in Fusions 3D view but with dense models it tanks
literally reducing the frame rate to a speed that makes it hard to work with.
The same model loaded in Alias provides a fluid and smooth workflow no matter if the model
has 3000 or 9000 surfaces.
So it cannot be my hardware which is why I made the Alias test.
The same model tested on a surfaceBook pro running win10 and using a much weaker GPU
runs dramatically faster than the MacPro I have with 2 GTX 970s.
So it seems that in addition the Mac version of Fusion has a openGL speed problem compared to
the Fusion for Windows.
Even selecting patches in Win is faster - at least the engine showing the patches being blue and selected
runs noticeable faster on the surfaceBook.
I am not sure if the offenders are:
- the selection / highlight system
- the added effects etc in 3d view
- or the 3D view display engine in general.
However something really is making Fusion unable to deal with dense cad data I tested here in my studio
but also in the engineering department yesterday at work at Wayne State.
