Speed up material preview

[haikalle]

Hi!

JuhaW I think one way we could improve the v-ray/blender is the change the python code where are settings for rendering material preview. It's too slow right now and if we found those settings and lower them a bit, preview could be much nicer
to use. But I haven't find those settings yet. Do you happen to know where to look?

bdancer You might able to help to give a location too

Maybe its "..\2.79\scripts\addons\vb30\preview\preview.blend "-file and its render settings.

Yes I found that also and it seams to have already quite low settings. I wonder why it takes so much time to update the preview. Need to do some more testing.

it seems very slow to show the settings changes.
Is there something to do to speed up this?
