Interesting. Installed the CUDA 4.0rc2 driver tonight, and just happened to notice a bunch of new extensions, many pulled over from GLES-land, but some not. Anyone got more info on the NV_* extensions?

ARB_shading_language_include EXT_texture_compression_dxt1 EXT_texture_format_BGRA8888 EXT_texture_type_2_10_10_10_REV NV_alpha_test - ???? NV_blend_minmax - ???? NV_complex_primitives - ???? NV_fbo_color_attachments - ???? NV_fragdepth - ???? NV_texture_lod_clamp - ???? OES_depth24 OES_depth32 OES_depth_texture OES_element_index_uint OES_fbo_render_mipmap OES_get_program_binary OES_mapbuffer OES_packed_depth_stencil OES_rgb8_rgba8 OES_standard_derivatives OES_texture_3D OES_texture_float OES_texture_float_linear OES_texture_half_float OES_texture_half_float_linear OES_texture_npot OES_vertex_array_object OES_vertex_half_float

Note: this is on a mere GTX285. So there may be other goodies lurking for Fermis that I can't see on this box.

The ARB_shading_language_include is about GLSL or CG?

It's ARB, and they don't use CG.

I don't even know why I ask that.

I was excited as much as you about a month and a half ago, when I saw those extensions for the first time, but then all enthusiasm gone when I found out what those extensions are about.

None of them are actually useful for desktop GL. They are all for Tegra.
Specs for those extensions are not available yet, or I'm not informed about. :)

For example NV_complex_primitives returns QUADS as a primitive type.

So these are OpenGL ES extensions.

It makes sense NVIDIA release OpenGL extensions to work with its mobile processor !!!
