Cineware much slower than Cineware 4D

I hope this is a me thing, and I'm just being stupid.

I've got a file that is using the Standard renderer in Cinema 4D, and will render an entire frame in 1 minute.

When I jump over to After Effects' Cineware, using the same settings (or so I think), the same frame render takes 5 minutes. I've got a few of the Cineware layers, allowing for Depth Pass and Object Buffer, as well as RGB.

Still, upon AE render (Standard - Final), I see multiple spikes in my CPU, each one lasting amost 2 minutes. There are 3-4 of those, making each AE render soooo long.

It seems like AE is rerendering for each instance of a layer. Is that possible/necessary? What needs to happen for AE to render in one minute, instead of 5?

Thanks guys!
