I’m editing a model with 34 objects in it, and currently a mesh with about 10-20 materials and 600k faces.
When I select 500k of those faces, just rotating around the viewport tanks my framerate to about 1fps.
Editing in general is about a 1s wait on anything I do. I’m using local view and the rest of the faces hidden.
I’m on a 1080ti, i7-6700k, 32gb ram, using today’s build of 2.80 (as of posting).
EDIT: Hmm… switching from UV/Editing to Modeling workspace and then back again seems to have solved the framerate issue, but editing is still dog slow. Just a circle select takes 0.5 seconds.
EDIT: Operations are still painfully slow. Unwrapping 21k polygons took more than 5 seconds. Rotating the result is again, at most 1fps in the UV editor.
