opengl display a image spend too much time

[chenghaibo]

my program load a bmp image and display it, after start up it, we should wait for a about 4.7s, then the screen would display the image.

maybe you can tell me what bsp version you use?  I can check the gpu, as I known, the latest version improve the performance.
