NVIDIA has released Cg 2.0 beta a few days back. I downloaded the new version including the docs and was browsing through them. What particularly interested me was the sentence “New OpenGL profiles (gp4vp, gp4gp, and gp4fp) for GeForce 8 extensions” in the features list. It’s a little bit confusing though, because the docs don’t go into how exactly to do that, or is it just some extensions. One another thing that seems a miss is how exactly to access new DirectX 10 features from Cg, or am I missing something? I don’t have a DirectX 10 compatible card so can’t test anything really, but I checked out the examples provided with the SDK and there seems to be no examples for DirectX 10.

The docs mention 2.0 is compatible with 1.5 so  I tried out some of my older test shaders written with previous versions (1.5) and they worked OK. But then again those weren’t pretty extensive.
