I had 2.78 and decided to install 2.79. I just installed a new hard drive and wanted to see if I get any performance boost from it. My problem is that blender 2.79 seems to work ok but slower. All my addons were supported. But 2.78 somehow broke. It is not a major issue but when I close 2.78 it kills the program but blender.exe is still in task manager using tons of cpu and memory. It stays on until I kill it manually. As far as I know I did not do anything to my 2.78 install. Just copied my addons from it.
Also another question I have. Blender never seems to use more than 25% of my cpu (excluding anything rendering related)? Sometimes when I have lots of particles-converted-to-meshes objects blender slows down to crawl when I select stuff, add modifiers or unlink the objects… but I can’t figure out what is slowing it down. Cpu peaks at 27%, gpu use is 360mb memory and not even 1 percent gpu. Hard drives are not doing anything or very little and memory is used about 60% of all 8gb. It is an intensive scene, about 15000 objects… but what exactly is my bottleneck here?
