This means that they render equally quickly. The difference in the number of verts means only that more memory is being used.

Used a demo so it'd be mostly consistent. I did have to spawn the modle roughly 100 times but this would mean if a team uses DMXs from Blender it will have worse performance than SMD or using another program to export everything.

And do you have any mirror or edge split or subsrface subdvision modifiers on the object in Blender?

I don't use Blender so I don't even know how to add a modifier. I understand that the count can be different from in Blender the issue is how absurd it is since StudioMDL matches vertices from a DMX based off their indices. It also messes up my importer since it bases smoothing groups off of the indices.

In Blender, are the vertices of the mesh connected? (Before you do the export?) And how many vertices does Blender say the mesh has before you export?

Yeah they're connected and at the top it says there's 2233 verts

The left one is exported from Blender and right from Max you can also check this by exporting an SMD instead. I believe this is caused by every face being exported with unique normals.

The importer seems to ignore any rigging and every mesh after the first in the file.
Here's a dmx with a cylinder rigged to two bones and a box next to it
