Hi guys,
I'm experiencing the same issue, using only cproxies and cscatter and some plugins like bercon maps, floor generator. All scattered instances are cproxies with enabled.
Look the attachements.
The biggest difference is not visible in these numbers - it's tansforming vertices - from several seconds in the begining rised to cca 7:30 minutes on 20th frame.
I will be able to send the scene on this friday probably. The animation is not crucial for me, I'm doing mostly stills, this was just a preview for possible output.
Adding some info:
win10
max 2019
corona5
amd threadripper 1950
