Hey again

What is the total amount of polygons does a 3D model have to have to beable to run on the psp without any problems?

Is there a limit to the amount faces the model has to have???

I think the maximum is when you used all your ram for the vertex scructs you use.

it depends on the rest of the program (ie, how much ram the rest is using)

Well, Im only using 45mb of ram, or trying to keep it there. I dont need another 800200D9 error because my packer program goes over the ram.

65535-2 if it's a triangle strip
65535/3 if it's a triangle list
that's the maximum you can draw in one drawcall. you can splitup your mesh in as many of those parts as you'd like, then you've no limit.

Realistically? A few thousand to a few 10s of thousand per frame, textured, normal sized. If many of the polys get big, or there's lots of alpha, then it'll get slow. You need to look at the fill-rate specs to get anything more accurate.
