The slowdown in render viewports Tweet

[voon]

When in Octane standalone, the UI remains zippy and usably fast when its doing its constant rendering. Not so in Blender: Switch the viewport to render and things freeze as it renders (or rather become extremely slow). Is this just the way it is with the implementation of octane into blender or did I overlook a setting somewhere?

With my limited experience with Octane for Blender (one project), I can offer the advice of trying to switch the rendering type between Global, Scatter or Movable Proxy. Info in the manual is found here: http://render.otoy.com/manuals/Blender/?page_id=51

Are you rendering on the GPU used for your display?

Hello Roeland

Yep, as I only have one GPU (my 670 GTX). But that's the same Situation for Octane Standalone or Blender ... but I imagine, the way data pases between the two and other "overhead" or the way blender allows the plugin to interact causes the slowdowns. In blender I basically have to set it to pause if I want to do something sensibly. In Octane Standalone it kind of stays more or less fluidly usable.

By the way this is no complaint ... I'd just like to understand it

Blender uses OpenGL to draw user interface (it is - it uses GPU hardware heavily to draw all the entire UI). So, the heavy display's GPU load has more impact on Blender UI responsiveness than on standalone's.

I see .. thanks again.
