speed...

You could use display lists and vertex arrays for some speed up... sometimes.

A better description of what tutorial you are on and your problem would be appreciated, but generally, there are a number of things you can do, but from what you describe, it sounds like you have a fillrate problem (which you can''t really do too much about). This is probably the case if you have a gf2. Also, never use glVertex3f() or glVertex3fv() for more than a few polygons. They are extremely slow. Instead, use OpenGL''s vertex arrays. You should also minimize the number of API calls you make per frame. Turning off things like lighting will also help. Hope that helps.

do vertex arrays provide an immense speed boost?

Ok,I realized I''m using too much glVertex3f()(thanks to GreatOne) and that''s what slowed down my programs, I''ll use vertex arrays instead. I also modified to code a little bit and gained a little more speed, so now the program runs pretty fast even if the objects are closer like I explained in my first post. Thanks for your replies.

How to use Vertex arrays ?

Beyond your specific coding style, also make sure you use optimal high level algorithms. The overall algorithm your program uses is the biggest determining factor of the program''s speed. I''m assuming you already know that, but it''s still good to reinforce that statement.
