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.<br>
<br>* GL_ARB_texture_compression_rgtc - Promoted to Core feature as of OpenGL 3.0<br><br>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)." <br>
<br>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.<br><a href="http://www.opengl.org/registry/specs/ARB/texture_compression_rgtc.txt">http://www.opengl.org/registry/specs/ARB/texture_compression_rgtc.txt</a><br>
