What's New in OpenGL 4.5

The OpenGL 4.5 and OpenGL Shading Language 4.50 Specifications were released on August 11, 2014.

New features of OpenGL 4.5 include:

  • Direct State Access (DSA)
    object accessors enable state to be queried and modified without binding objects to contexts, for increased application and middleware efficiency and flexibility;
  • Flush Control
    applications can control flushing of pending commands before context switching – enabling high-performance multithreaded applications;
  • Robustness
    providing a secure platform for applications such as WebGL browsers, including preventing a GPU reset affecting any other running applications;
  • OpenGL ES 3.1 API and shader compatibility
    to enable the easy development and execution of the latest OpenGL ES applications on desktop systems;
  • DX11 emulation features
    for easier porting of applications between OpenGL and Direct3D.

New extensions to OpenGL 4.5 include:

  • GL_ARB_clip_control
  • GL_ARB_cull_distance
  • GL_ARB_ES3_1_compatibility
  • GL_ARB_conditional_render_inverted
  • GL_KHR_context_flush_control
  • GL_ARB_derivative_control
  • GL_ARB_direct_state_access
  • GL_ARB_get_texture_sub_image
  • GL_KHR_robustness
  • GL_ARB_shader_texture_image_samples
  • GL_ARB_texture_barrier
