It may be able to display a billion polygons, but it certainly can’t keep a
billion unique polygons in video memory. Each unique point requires a bare
minimum of 12 bytes, and usually requires more than that (for color/texture
info). The indexes into the point list used to draw the polygon are usually 2
or 4 byte integers, so that’s either 2 or 4 more bytes per point. Even with a
fully connected triangular mesh, you’re talking about 1 point and 3 indexes per
triangle. (You can draw in other modes that use less memory, but they also tend
to be a lot slower.)
