This month the last release drivers appears to be for GeForce, Forceware 301.10; and for Radeon, Catalyst 12.3 (8.951).
These tests have been done on Windows 7 64 with the OpenGL Samples Pack 4.2.4 branch, still in development, on an GeForce GTX 470 and a Radeon HD 5850.
Drivers Forceware 301.10 brings the support of AMD_multi_draw_indirect, an extension that would have gave a 2011 award for best extension of the year even if I can picture a lot of possible improvements. NVIDIA also exposes the new NV_bindless_texture extension (2012 nomine...) which can be seen as the first virtual texture implementation available. Infortunately this extension is Kepler only so I can't play with it for the moment. NV_shader_atomic_float adds support for 'add' and 'exchance' atomic operations for float values. I haven't tested it yet but it will be part of the OpenGL Samples Pack 4.2.4.
Also it is worth to mention that NVIDIA has put a continuous effort on the debug output implementation which now provides an incredible amount of messages including descriptive errors, warnings and performaces feedback. An outstanding work which is extremely useful for the everyday work of an OpenGL programmer.
AMD released the extension specifications of GL_AMD_vertex_shader_viewport_index and GL_AMD_vertex_shader_layer which gave me the opportunity to write a sample for it. These extensions allow to set the gl_Layer and the gl_ViewportIndex in a vertex shader which avoids the overkill of using a geometry shader for this only purpose.
Now, a disturbing problem that appeared on both AMD and NVIDIA implementations. The respective linkers are no longer reporting the Shader Interface Matching issues like they have to do. This is necesseraly a rescent issue because it's the kind of issues that happen all the time when writing GLSL shader code. Considering that we have no API to query the outputs and the inputs of respectively the vertex shader stage and the fragment shader stage, I think it's at least a major problem.
When both sides of an interface are contained in the same program object, LinkProgram will detect mismatches on an interface and generate link errors.
Once again, don't forget to contribute to the OpenGL community by reporting your bugs!
