8-bit | 10-bit HEVC Render | Resolve 15

Rendering 8-bit HEVC only uses the GPU, leaving the CPU untapped. Reviewing Activity Monitor while 10-bit is processing reveals a continual handoff between the GPU and CPU. Possible reasons include 10-bit not being fully supported as a hardware accelerated process within the GPU, or simply a snag in the recent master release of DaVinci Resolve 15.
