Nvidia NV43 (6600 and up) can actually do ray-tracing in realtime, as well as displacement mapping, bump mapping and depth of field. I can whip these shaders up in Nvidia FX composer in about 10 minutes for each one, so applying them to the core coding of the openGL section of code wouldnt have been too hard. that said, I dont think its needed, I just like the fact that when viewing the textures in the document window preview it actually runs smoothly! it would have been nice to be able to up the texture size that the preview uses to decrease the blockyness and why did they go for OpenGL? DirectX 9c has much cooler features, and runs much better on ATI cards, only NVIDIA holds the OpenGL crown (and is the only reason OpenGL is still around!)
