I''m writing a simple 2D "engine" using ortho, and I''m trying to decide how to sent polys to OpenGL. I don''t really care that much about performance, but I don''t want immediate mode. I don''t want to use extensions, and it should run on low-end hardware.

Probably in 2D your bottleneck is fill rate so there is no real difference...and on low end hardware (and not only) passing glVertex2i can be FASTER than use VertexArrays (in theory VertexArrays should work better but it is not always true).

OK, would I be able to call
GLBegin()
for(i=0...)
{
Object->Draw()
}
GLEnd()

I don''t think so. I don''t want to use GLBegin/End for every sprite. If that would work, I might use immediate mode, but there will be a variable number of objects.
