"I work with heavy Rhino models a lot. I've noticed no significant slow down- I guess it depends how you bring it into Max though. After a lot of testing different formats etc, I use a Rhinoscript to export each layer as an obj file (highest geometry settings). I use a Maxscript to batch import all these into Max because I find it works best with "import as single mesh" ticked. Add an Edit Mesh and Auto Edge Visibility everything, add a Map Scaler OSM modifier set to 1m and it's all good to go. There's a couple of extra steps I do, but that's the basics, works great."
