Hi Andreas,
This work was done specifically for polysurface and extrusion wire drawing. If textured meshes and blocks are dominating the display time for your model, then you won’t really notice much of a difference at all. I’m also noticing in your screenshots that almost everything is a straight line. GPU tessellation can have a slight improvement over the older technique for straight lines, but probably not as much as curvy surfaces.
I am working on blocks right now, so hopefully I’ll have something to report in the near future that will have an effect on this model.
A good test to see if your card works well with this feature is to test the bike model in wireframe which can be found here:
