Yea, this is what i want to know, thanks Jan :)
I already made some 2d games in ruby using gosu and now im going to 3d
Just another question, i'm dont know opengl already, i'm just starting 
my studies, you said "offload anything on GPU", how can this offload can 
be done?

There is a Gears demo made in ruby with opengl comparing with c, it uses 
display lists, so get almost the same speed of c, this is what you say 
about "offload anything on GPU"?

link about the gears demo
