DXGL requires hardware-accelerated non-power-of-two textures. To pass the OpenGL 2.0 conformance tests, later NVIDIA drivers for GeForce FX fake non-power-of-two support by emulating in software, which means that if a non-power-of-two texture is used, the output is on the order of seconds per frame.
At the end, I use a custom 1024x512 resolution to show the difference.
See http://www.opengl.org/wiki/NPOT_Textu... for more information.
