merged vertices vs seperate: what is the speed gain?
Take a model with 60 000 vertices and 60 000 triange points.
and one with 20 000 vertices and 60 000 triangle points.
What is the performance difference?
before you try something like that - whatever modeling software you're using has an option to merge duplicate vertices or split existing vertices (usually you'd select a portion of mesh and 'separate it', creating duplicate vertices along a seam)
Surely having separate vertices would increase the overall object file size (multiple points in the same location) and hence memory impact, effecting performance? The more information the program has to deal with, the more computation it has to do each time it tries to do anything. Follow the suggestions above and see what real-world impact is in your scene.
You get different appearances for shared versus separated vertices. Pick the one that looks the way you want.
If you're in it purely for speed, less is always better, end of discussion.
