I have a project with a scene view of several elevation surfaces and several hundred thousand vector data points plotted in vertical columns. This used to all render within about 20 seconds but recently it takes much, much longer. The 3D surfaces render in the same time but the vector data now takes too long to render - about an hour I guess, if I left it running. The only thing I can think of that has changed is the updated to 2.9.0. Was a default setting changed perhaps? Is there a way to speed this up?
