AMD Catalyst 12.6 Beta Available (Monthly Releases are Over), Two New OpenGL Extensions



AMD Catalyst logo


Where are the 12.5 drivers? Here is the answer:

With the release of the AMD Catalyst™ 12.6 Beta driver (“Catalyst”), AMD would also like to announce that we are moving away from our Monthly Catalyst release plan. Our goal is to ensure that every Catalyst release delivers a substantial benefit to our end users; as we have today with the release of the Catalyst 12.6a Beta. We will still continue with the Catalyst naming convention; Catalyst: Year.Month. You just won’t see a new driver every single month. We are confident that this will only benefit the end user; you’ll only need to upgrade to a new Catalyst driver, when it makes sense.

You can download the beta of the June 2012 edition of Catalyst drivers from this page: AMD Catalyst 12.6 Beta Driver. Cat 12.6 are available for Win7, WinXP and Linux.

For Windows 8 Release Preview, you can download the graphics drivers from this page: AMD Catalyst Driver Windows® 8 Release Preview.

Catalyst 12.6 beta brings two new OpenGL extensions compared to Catalyst 12.4:

  • GL_AMD_query_buffer_object
  • GL_AMD_sparse_texture

Catalyst 12.6 is an OpenGL 4.2 driver (exact version: 4.2.11733) and exposes 239 OpenGL extensions (GL=218 and WGL=21) for a Radeon HD 7970 under Win7 64-bit.
