Render codecs & CPU & GPU usage

PostSun Jul 21, 2019 1:43 am

Interesting, I found very different use of CPU resources when rendering cache or optimised media in the codecs provided by Resolve studio 16b6. 2 x Xeon 12 core 3.0Ghz E5-2687W v4; EVGA RTX 2080Ti Black.

Win performance monitor shows:

Cineform: only 12 of the 24 CPU cores working hard; GPU 3D around 30%
Uncompressed: as above.
DNxHR HQ: all 24 cores working at max, GPU 3D around 40%

Consequently it takes around half the time to render - I know what codec I'll be using (!), still, it seems a bit odd.

(Deliver uses all cores & around 40% GPU. Memory is nowhere near saturated with 64GB ram).
MacPro 7,1, 16 core, 2TB, 192GB, Vega II 32GB. UA Apollo x8, DeckLink MiniMon 4k. 8TB RAID 4 OWC Thunderbay 6, 2TB RAID 0 Sonnet M.2 4x4. Dell U3415W & BenQ SW2700PT. Nuendo, FCPX, Resolve Studio 16.2.
