Sorry Kontour, you couldn’t be MORE wrong.
I admire blender, I’ve used it to really good effect, ‘when’ it works.
I thought we should stop glossing over issues blender has.
If you only work on low resolution meshes, you would be fine, but we don’t all limit ourselves to those kinds of things.
I have a mesh, all one piece that is growing while I try to keep the polycount low as possible ( ie: as I work ) , which is 1.3mil tris, and if I go into edit mode which is often needed, blender ‘crawls’, making it impossible to work in.
My rig isn’t ‘state of the art’, but I guarantee you its not slow either, so don’t go there , phenom II x4 3.2ghz, HD 7750 2gb , 8 gigs of ram windows 10 64bit.
Its not a powerhouse I realize, but its far far from slow .
Blender developers ‘know’ about the problem , trust me and you can look for yourselves if you wish to verify.
The edit mode is old GL code as I understand it, and honeslty even approaching 66k tri, blender in edit modes is very annoyingly sluggish.
That’s why I said, maya for the win, and I can’t ev en afford maya 
That should tell you something
thx
