Here's a couple a tips that might help....
First of all... Bones animated models are way better than points because the file size is so much smaller. That really helps with frame rate etc...
Then... you also need to use textures that have been optimized. I have found that using .dds files rather than .bmp or .tga etc... makes the file size way smaller and therefore the game runs much smoother...
Therefore... add it all up... use bones animation with .dds textures and your game runs way smoother...
Just my thoughts...
