AECOsim V8i SELECT series 6 Lagging and crashing

Hi,

Some of my models are running extremely slowly and after a while they crash and I have to abort. This isn't stopping work but its slowing it down significantly. I have one MC referenced in which has approximately 45 models of both 2D and 3D, I am working in 2D but within a 3D seed. Isolating the areas I work with seems to help speed things up slightly but not much. My OS is Windows 10 and I have 32GB RAM. The issue is the same whether I am connected through WiFi or direct.

thanks for any and all help you can give.

Mark
