My system:
iMac 2015 i7 32 Gb ram
C4D R23
Running the beta CR 7 daily builds. Very happy about version 7 btw.
All my renders are VM. I use the hair tool to brush ground cover on my landscapes. Huge amounts of data :-)
VM ia around 40Gb or a little less. You can see the renders here on the top left.
https://francoisverhoeven.comImages are rendered at around 2400x2400 p. Renders up to around 200 sl. Rendertime around 12 hours but at about 10 min reasonably at 5 or 6 sl. Scene parsing 5 to 10 min before render starts. I wonder if GPU render engines or a PC (instead of a Mac) would reduce parsing times. Actually parsing times slow down my design process much more than render time. After 1 or 2 minutes rendering I can evaluate the image. But because of parsing times I can only do 4 or 5 image evaluations an hour.
