because you''re system can''t handle all of the polygons and/or the fill rate. the bigger it is the more polygons you''r drawing. on most 3d hardware that shouldn''t be a problem. try adding these lines to your code:
glEnable(GL_CULL_FACE);
glCullFace(GL_BACK);
that way only the polygons facing you will be drawn.
