I’m on a laptop with Optimus (Discrete GC: Nvidia Geforce GT 640M and Integrated GC: Intel HD). And ever since the 2.79 builds came out with GPU+CPU rendering I have had a problem when running Blender. My problem is that with dual render builds, it seems that something is always soliciting the GPU and CPU even when I’m not doing anything in Blender and I can see the temperatures of my whole system (gpu and cpu) slowly but steadily increasing until my fans kick in and the temp stabilizes at around 57C (on a cool day).
I don’t have this issue/behavior with Blender 2.79b without Dual render, and the temp when doing nothing is around 45C. On a hot day I don’t use Blender because it simply makes my laptop too hot.
I could keep using 2.79b, however I want the bevel node, the displacement node, the vector displacement and the AO node.
Does anyone know if a build exists without dual render (just with GPU as in 2.79b).
If not, does anyone know where in the code that could be disabled?
Thank you for your help.
