I'm working on pretty complex scene in C4D with a lot of different lights and glossy mats. I chose to go with PMC to get rid of hotpixels in PT. I thought that some extra rendering is not a big problem as I have 7x1070 GPU farm(PC2)...but here's the thing..it's slower on PMC algo than 2x1080(PC1).
This problem only appears in PMC algo, so I don't really understand what is the problem.
PC1:
- i7-4790k
32GB RAM
2xMSI 1080 gaming x
SSD win8.1
PC2:
- Xenon E5 2609v3
64GB RAM
7xMSI 1070 gaming x
HDD win10
Here's few screenshots:
