Draw Shaded Preview Geometry mode is very slow

Hi, since the few last Rhino5 release the shaded mode in grasshopper became very slow...I am still using 0.8.0066 with Rhino Version 5.0 (5.1.20801.1108, 08/01/2012)

Is this a Rhino issue ? or Grasshopper issue? Does the new Grasshopper release remedy that?

thx

There's no difference in the way 0.9+ draws meshes. What display mode are you using in Rhino5?

hello david, I am using the "standard" shaded display...not customized

That's weird - I thought that I would not be alone with that issue. One thing I am sure is that it appears since the 3 last Rhino5 release... I am working on the same definition since a few weeks..

To be more precise the shaded display is very slow, and doesn't display wire.

I will try to explore a bit more and give you more info.

thx

Jeff LaSor (our in-house display guru and OGL wizard) has been working on the Rhino5 shading pipeline lately. I think he's both trying to add more feature and optimize the stuff that's already there. This may well be a temporary problem.

I'll run some tests in the latest Rhino5 beta to compare it to Rhino4 display performance.
