How do I balance render load between Gpu and CPU I have a gtx 1080 and ryzen 2700x. The gpu is a little faster when testing render times. I would like to balance render load between the two because the system is rendering mostly on the CPU when I hit F12, 100% CPU and about 20% GPU utilization. I know Cycles utilizes both processing that's why I am asking. I am 2 weeks into Blender coming from C4D so I am a Blender novice with good 3D knowledge.

I am basically testing materials and lighting using a smooth shaded Suzanne. On this scene I have a Sub division modifier divided 2x and quality set to 2.
Solidifier modifier with thickness set to 0.02m.
Glass Bsdf IOR  set to 1.5.
I have an hdri hooked to the colour of the world shader/light

I am using Blender version: 2.80 (sub 72) build date: 27/05/2019, 18:09 and 4.5.0 NVIDIA 388.13 drivers on Windows 10 1903.

Any help is highly appreciated.
I think I found the answer. Under Cycles, Sampling, Integrator choose "Branched Path Tracing" instead of the default "Path Tracing". I don't know how I missed this the first time.

For the scenes I have tested, GPU utilization is on average 60% and going as high as 100% at some point in some scenes.
