This September release of Cg 1.5 fixes bugs introduced by the performance work in the August 2007 release.
This update includes numerous improvements to the NVSG SDK as well as a new VisSim demo, which illustrates the integration of physics (Bullet physics system), audio (OpenAL), and graphics through Producer, Cal3D, FreeType, and of course NVSG.
The Front Line Awards are meant to honor products that enable faster and more efficient game creation for advancing the state of the art. This is exactly the goal of our developer tools, books, and GPUs: to help raise the bar of real-time graphics, and to deliver great performance while doing so.
Developers themselves choose the nominees, so nominate the NVIDIA tools, books, and GPUs that mean the most to you at http://www.frontlineawards.com/.
Potential nominees by category:

This latest FX Composer version features improved COLLADA file compatibility between applications, as well as other minor bug fixes and improvements. As always, please share your feedback on our developer forums.

The September 10th update to the NVIDIA Shader Library includes new HLSL and CgFX samples for techniques including deferred rendering, texture-space diffusion, color-space conversions, surfaces with fine hairy fuzz, and simplified support for COLLADA shared-surface shadowing; in addition, many existing shaders and #include files have been broadly upgraded to improve support for realtime shading inside DCC applications like Autodesk 3DS Max and Softimage XSI.
