Material Tab and thumbnail preview being extremely slow

[wim (Wim Dekeyser)]

Hi Iyang -

@Iyang_Huang

I don’t think updating will resolve it because this issue is never specifically addressed.

I think this issue is being discussed here:

Material Dialogue and List

Thank you for the test model. I tested with the following combination. EnableGL = True EnablePreview = True EnablePreviewCache = False And now I can also see a lag when opening the dropdown. When the Cache is set to false, then we do not cache the previews and they get always regenerated. Can you make one more test for me. How does the dropdown work when both of these are set to false and then restart Rhino? EnableGL = False EnablePreview = False.
