Thanks for the file. Turning off AA here doesn’t help the display speed when the render mesh is displayed. The PolygonCount reports 11.7 million polys but it’s fast in shaded mode if the render mesh wires are off.
@stevebaer are mesh wires yet to optimized or is this slowdown to be expected? When zooming out, the spheres essentially become dots but it seems like we still try to display the individual wires on top of one another. Is it possible to reduce the level of detail for the wires as the view zooms out?
