Salad Boy strikes again! He did the same thing to me a few months ago.

Considering FleepGrid is running on an old P4 with 4GB RAM, I've been relatively pleased with its performance with around 11 regions, some of them with lots of content and scripts.  The only major concern has been the CPU consistently pegging around 75-80% usage after all the scripts are loaded (it always hits 100% during start up).

What the heck was going on, I wondered, the only regions I had left to load were my three hypergate regions which are basically small islands with a few signs and very few scripts or objects.

I couldn't imagine what the heck was going on with that nearly empty region but upon investigation, I discovered 600 spheres set to physical under the waterline, each taking up precious CPU resources.

Hopefully this will mean a lot less laggy experience on FleepGrid and a lot less stress on my poor old PC (which I'm completely surprised was even able to handle 600 physical objects at once!).
