The biggest problem is the Operational system, every new Windows release is worst than the other, this is why I use a modified version of Windows 95 prior to OSR2. My limit was achieved with 8 characters with clothes, background, ground ,props and shadows with a Pentium I 200 Mhz and 64M Ram. I also have done a scene with 18 charcaters without clothes and shadows enabled. Now I have 160M Ram, but I don't know which is my limit

Stupidity also evolves!
