its difficult to belive there are no opengl solution fo this problem.
ive just used vbo bufferes, display list, reduces number of paints to minimum and still repaint takes too long.
please point me to the best way for fix it.
From reading your other post, does using GL_FLOAT instead of GL_DOUBLE help with performance? Also, are you doing things every frame that only need to be done once at initialization?
i noticed the same and now im using float - little help but no shock
