    Why very poor support GL extensions Ivy bridge  on Windows compared than mesa linux driver?

      Hello again 2015.. spends oblivious of OpenGL support on Windows.

       

      mesa/mesa - The Mesa 3D Graphics Library

      The OpenGL vs Mesa matrix

       

      On Windows missing a lot extension..Ivy bridge (Only supported hasswell and higher) but supported on Linux (Nightly mesa 11.1 driver)

       

      Opengl 4.2

      GL_ARB_shader_image_load_store  supported on mesa driver after 11-08-2015 day patch but.Intel only supported hasswell on Windows, ¿Any reason intel?


      Opengl 4.3

      GL_ARB_clear_buffer_object

      GL_ARB_copy_image

      GL_ARB_texture_view

      GL_ARB_shader_storage_buffer_object

      GL_ARB_shader_image_size

      GL_ARB_invalidate_subdata

      GL_ARB_explicit_uniform_location

       

       

      Opengl 4.4

      GL_ARB_clear_texture

      GL_ARB_multi_bind

      GL_ARB_texture_mirror_clamp_to_edge

      GL_ARB_vertex_type_10f_11f_11f_rev

       

       

      Opengl 4.5

      GL_ARB_clip_control

      GL_ARB_conditional_render_inverted

      GL_ARB_derivative_control

      GL_ARB_direct_state_access

      GL_ARB_get_texture_sub_image

      GL_ARB_shader_texture_image_samples

      GL_ARB_texture_barrier

      GL_KHR_context_flush_control

      GL_EXT_shader_integer_mix


      These extensions are supported HW ivy bridge on linux mesa 11.1 driver but again not on Windows..


      It is incomprehensible to leave the support of a HW technically supports by some extension ..
