Performance problem

[Vladimir Baltchev]

In fact you have 3 gl.h in cygwin but only one library - libGL, and it's 
the X11 one...

That's because it is hardware accelerated on Unix.

    We are trying to use cygwin to port our applications on Windows. The
    cygwin's OpenGL gives us the dependency on the X11 cygwin simulation
    on Windows which is slow, I gess... 


They are 2 OpenGL implementation for Cygwin:

A slow one for X11: everything is rendered in software.

A fast one for native Windows apps. The OpenGL package enables you to 
use it. It uses hardware acceleration if available.
