There is a new core extension required by OpenGL 4.3 that should be important to note. OpenGL 4.3 requires support for the ASTC compression. * GL_ARB_texture_compression_rgtc - Promoted to Core feature as of OpenGL 3.0 See Section F.1 ( Page 301 ) of the OpenGL 3.0 Core Specification. This specifically states as a new feature "RGTC specific internal compressed formats (GL_EXT_texture_compression_rgtc)." NOTE: This has not changed much, but was reworded... So also reconfirm against Section : "H.3.3.45 RGTC Texture Compression Formats" on page 692 of the OpenGL 4.4 core specification. http://www.opengl.org/registry/specs/ARB/texture_compression_rgtc.txt * GL_ARB_texture_compression_bptc - Promoted to Core feature as of OpenGL 4.2 http://www.opengl.org/registry/specs/ARB/texture_compression_bptc.txt * Adaptive Scalable Texture Compression http://en.wikipedia.org/wiki/Adaptive_Scalable_Texture_Compression * KHR_texture_compression_astc_hdr - Promoted to Core feature as of OpenGL 4.3 http://www.opengl.org/registry/specs/KHR/texture_compression_astc_hdr.txt
