Cycles CPU Utilized Capacity

Hi @nathanletwory

I am testing Cycles for Rhino and am not able to use the CPU rendering to full capacity. Looking at the Windows Task Manager, I am seeing a utilization of 30-40%. The number of threads is set to the number of logical cores. The throttle value is set to 4. Lighting is done via an HDRI.

Thanks for looking into this.

There seems to be a performance problem with the production render method that I haven’t had time to look into yet.

I created a report RH-40199 to track this.

Thanks.
