It's easy to get caught up in the hype instead of the facts. @k_szczech:

The only OpenGL - rendered image is the one in bottom-left corner - it's from "Human head" demo from NVIDIA. Anyway - comparing images between OpenGL and DiectX doesn't make too much sense. It's all about the algorithm you implement in your application/shaders and the quality of model/material you use. All OpenGL renderings could be rewritten to DirectX 10 and vice versa. There would be no difference in image quality. We’ve discussed this image not long ago on OpenGL forums.

Thanks for the clarification. I learned something new. I've never really known much about gaming, so I don't keep up on it very much. I ran across this picture on the net someplace and was impressed. Now I know a little more about it thanks to you. -Derek Cool Eddy.

The thing is: as long as hardware vendors keep making extensions for OpenGL to access certain hardware capabilities OpenGL will be able to do just as much (if not more currently) as DirectX. Shader Model 4.0 is only accessible in DirectX through version 10, which means Vista only. SM 4.0 in OpenGL is accessible through Windows XP if your hardware can support SM 4.0. Image quality depends on the Shader Models used, the quality of the hardware and the quality of the artwork most of all. OpenGL and DirectX are just APIs which means that they are simply interfaces to hardware functionality. Best Regards, Eddy Hi Derek, love the image you’ve posted.
