Rhino5 Matrix9 Rendering with CPU only or how to enable GPU?

We are using Matrix9 on Rhino5. I have just realised that it only uses CPU when rendering. ISnt it better to use both for performance? What should i do to activate Cycle to enable GPU rendering too? I have read about Cycle but i couldn’t find in under Tools.
Please help me with that.

Hi Sukeu -

You’d have to upgrade to Rhino 7 to be able to use the Cycles render engine in Rhino.
Matrix 9 does not work with Rhino 7 though…

Long story short, with the current setup we have a rendering option with CPU only? (Thus a GPU is just useless)
