Could it be that the Octane plugin in DAZ is always running in the background, even if I don't use the Octane viewport and the renderer?
Both my 2 GTX cards are running hotter after working in DAZ with the internal 3Delight renderer (I checked the temp in Afterburner).
I also have the Octane plugin for C4D (demo), but the cards don't kick in when I use the internal C4D renderer.
Thanks,
Peter.
