reduce texture size. if you built it, reupload with the simplest physics possible, even if you aren't using the physics.

(for physics, boxes are good, reducing to 0 is bad)

nah not mine.. All that I buy T_T

GlamAffair: then replacing all the textures is the best you can do. or find a brand that focuses less on extreme unique detail. you can select a display house and hit control+alt+T i think? and get a readout of the textures. lots of 1024x1024 messages pop up, probably not great texture wise. specular, normal, and mesh detail also all cost.
