Ok.
So i made a version of my app using ofMesh and ofVboMesh.
Seems to work but is quite twice as heavier in CPU ressources as the previous version !
Activity monitoring shows 67% CPU usage where i used to have 35% with the previous one !
Obviously i am doing something bad...
If anyone has some time to have a look that would be great
