Each model has around 30 skins which I have been using to change textures when the user mouse is over a certain entity. Also a lot of menu items use the same model just uses different skins. The nexus is set to 128 which I thought would be plenty and it worked but if I look at the resources being used by the menu it was around 260. So far with further optimizations I have brought it down to 184, and I still have work to do. When the game loads it actually only has to load 8 entities. I was a little worried before which is why I wrote in here because I was setting the nexus to 128 and it was taking up about double that. But now that it is starting to go down more and more I think it will be fine.
Most people these days have about 256 MB to 512 MB of RAM anyway I think, I hope. I would like to share the current build so that I could get help but there is no copyright on the title yet which limits me to what I can discuss in the forums. The game is supposed to go retail in 1 week and we still have so much work to do. This memory problem has delayed us quite a bit. Hopefully though we have it figured out.
So in a couple weeks you can see what I was talking about better I will post up a demo in Showcase 2 or you will be able to go to our distributors site and download a demo. I appreciate the assistance you have provided.
