ContextCapture memory usage

Hi.

I am currently using ContextCapture Desktop edition Update 19 v10.19.0.122 with the following hardware:
- Intel Xeon Gold 6240R 2.4GHz, 24 cores
- NVIDIA Quadro RTX 6000, 24GB GPU
- 128GB (8*16GB) DDR4 RAM
- 2TB PCIe Class 40 Solid State Drive
- Windows 10 Enterprise 20H2

I am currently surprised that only 8% (10GB) of the RAM is used in the production of the point cloud or mesh, although CC reports that the required RAM exceeds 16 GB (without tiling). CPU utilization is around 100% (see screenshot). Vulkan API and multiGPU processing is enabled (benchmark ~300).

Are there any setting options to speed up the calculation?
