Around 110 Megabytes in fact, but they're for 32 and 64 Bit editions of Windows 7 and Vista respectively. Consequently, there's only an optional download including this new control panel. AMD has refurbished their Catalyst Control Center and re-done not only the looks of it - but it's still in a kind of advanced beta. Problems can arise when your hardware device is too old or not supported any longer.Just days before the actual release, the man in charge for Catalyst software at AMD announced the 10.12 version of AMDs Radeon drivers as being „huge”. This will help if you installed a wrong driver. Try to set a system restore point before installing a device driver. Do not forget to check with our site as often as possible in order to stay updated on the latest drivers, software and games. You will need any one of the following Fermi based GPU to get access to the OpenGL 4.1 and GLSL 4.10 functionality: - Quadro Plex 7000, Quadro 6000, Quadro 5000, Quadro 5000M, Quadro 4000 - GeForce GTX 480, GeForce GTX 470, GeForce GTX 465, GeForce GTX 460 For OpenGL 2 capable hardware, these new extensions are provided: - ARB_debug_output - ARB_ES2_compatibility (also in core OpenGL 4.1) - ARB_separate_shader_objects (also in core OpenGL 4.1) For OpenGL 3 capable hardware, these new extensions are provided: - ARB_get_program_binary (also in core OpenGL 4.1) - ARB_robustness - ARB_viewport_array (also in core OpenGL 4.1) - GLX_EXT_create_context_ES2_profile - WGL_EXT_create_context_ES2_profile - GLX_ARB_create_context_robust_access - WGL_ARB_create_context_robust_access For OpenGL 4 capable hardware, these new extensions are provided: - ARB_shader_precision (also in core OpenGL 4.1) - ARB_vertex_attrib_64bit (also in core OpenGL 4.1) It is highly recommended to always use the most recent driver version available.
