My SU Pro 2018 has suddenly started running excessively slow.
Does anyone have a remedy?
Maybe I am imagining it and it is unrelated but I installed Norton Security Software and now my Sketch up is crawling and struggling to load external textures properly. Could it be the Graphics card?
I have been using a Norton firewall/antivirus on my Windows machines since I don’t remember when (20 years…?) and it has been remarkably trouble-free. Do Macs need one too, today?
As Mike asked, where are your textures coming from? Are they large?
SketchUp has a built-in limit of 1024 x 1024 pixels that can be tweaked to 2048 x 2048 with the “Use maximum texture size” setting in Preferences>OpenGL. Anything bigger than that gets reduced to fit and serves only to increase file size with no increase in quality. The reducing algorithm within SketchUp is rather crude so you get better results by reducing the textures in an image editor prios to applying.
