Looks like Nvidia don't want to be outclassed by AMD and have released GameWorks SDK 3.1 with the intetion of releasing parts of it onto github. They have already released FaceWorks and some OpenGL samples, with more to come.The license isn't quite as simple as the one AMD use for GPUOpen, but it's a start.Hopefully having more open code will allow AMD to inspect it more and not have so many issues with games using it like we have seen in the past. Not AMD's fault of course when a developer chooses Nvidia-only tech, but with it more open the possibility for AMD GPU drivers to work with them easier is there.You can find the github here , and the Nvidia announcement here Thanks for the info, Nel!
