I am trying to figure out why my company's 3D models are so CPU/memory "heavy" and I could use some advice. At my previous job I worked on heavy equipment which was quite a bit more complicated than what I work on now, but the models took less time to load and ran much smoother on a lower spec computer. For example, I could use a Space Mouse controller without any issues with most of the top level master model in session. At my current job the subsystem models are extremely slow and choppy. In most cases it runs so choppy/slow that I can't use my Space Mouse but everyone seems to think this is normal. Things improved slightly when we upgraded from WF4 to Creo 2, but I think things could be improved much much further.
The CAD admins at my previous job were much stricter about keeping models clean and lightweight. For example, they tweaked some settings to disable previews, disabled transparency, enforced proper layering, kept detail at a reasonable level, and required all models to be processed by ModelCheck before submitting to the data management system. Unfortunately, nobody enforces anything at my current job and most of the models are really sloppy.
At this point I would just like to hear any tweaks/settings that others have done to significantly improve performance in Creo 2. My goal is to compile a list of improvements and try each one of them one-by-one to determine what has the greatest impact.
