      I'm guessing testing of 4.1 features are what's holding up haswell.

          OpenGL 4.0 were released on March 11, 2010. Almost 7 years ago.

            They started testing immediately, but as the GPUs are super slow, initial testing hasn't finished yet. You can't release a product without QA.

              Yeah, I thought there was another 64 bit 4.1 extension missing, but was too lazy to look it up on the phone

                Now please something like that in r600 for the chips that need this emulated.
                Stop TCPA, stupid software patents and corrupt politicians!

                  There's also image load store in the vec4 backend needed for GL 4.2. After that I think it can jump the rest of the way...
