Matt Frodsham provides some strategies for maintaining good viewport speeds in cinema 4D, especially when working with larger models and scenes, walking through some of the things he does to reduce heavy calculations.

There is a constant wish for Cinema 4D to implement faster viewport handling. While this is a legitimate request, especially in terms of handling large numbers of objects, there a lot of steps users can take to help themselves

Matt defines areas of “calculation” and then goes through some layering techniques, using proxy objects, and some general housekeeping in collapsing merging and baking. Matt provides an extensive article full of techniques and tips for maintaining a speedy response from the Cinema 4D Viewport, as well as providing a hand list of resources for plugins, scripts and scene files.
