I'm not really asking a specific question here, just trying to get a better idea of a few things. First of all, I downloaded a plane model with 17,561 faces (9,367 vertices) all of which were triangles. The model draws (without textures, but with lighting) all fine and dandy at a healthy FPS. When I draw it in a 10x for loop, the frame rate slows to "noticeably laggy," bringing up several questions in me.
How many vertices and faces are usually contained in a level?
What can I expect a good number of faces to be if I were attempting to release a game for a level?
How many faces do most characters (enemies, main character, etc) have?
Should I convert to VBO's from the display lists that I am currently using?
Will I have to optimize my program because this is really a miniscule amount of vertices? Or is it more vertices than I'll need in most levels?
I'd hope some folks here can shed light on some of my questions and thoughts. Oh no! My inexperience is showing!
