Ok...i'm messing with VBO's and everything seems ok, however an implementation required to initialize a VBO with a NULL data pointer then map the vbo and upload the data...everything works ok, the model gets rendered (~35 000 vert, 70 000 faces) and i get ~ 160fps on a radeon 9600 xt...But if i set the data using glBufferSubData instead of mapping then writing i get ~340fps...i really can't understand what is going on! Please help!
