ATI Catalyst 8.12: Four New OpenGL Extensions!




Here is, fellow coders, the list of OpenGL extensions that are exposed by the graphics driver Catalyst 8.12 (BETA) for a Radeon HD 4850 under Windows XP SP2 32-bit.

Compared to Catalyst 8.11, Catalyst 8.12 introduces four new OpenGL extensions and renames one extension.

Extensions changed:
GL_EXT_depth_buffer_float has been ARB-ed: GL_ARB_depth_buffer_float

New extensions:
- GL_ARB_fragment_program_shadow
- GL_EXT_draw_buffers2
- WGL_I3D_genlock
- WGL_NV_swap_group

GL_ARB_depth_buffer_float brings a new texture internal formats whose depth components are stored as 32-bit floating-point values, rather than the normalized unsigned integers used in existing depth formats. GL_EXT_draw_buffers2 allows to specify a color mask and color blending operation for each render target. WGL_I3D_genlock allows to synchronize the refresh of the monitor to an external signal. WGL_NV_swap_group allows to synchronize the buffer swaps of a group of OpenGL windows. The OpenGL windows may be on the local machine or on distributed systems on a network.

All GPU Caps Viewer tech demos work fine.

Catalyst 8.12, like Catalyst 8.8, 8.9, 8.10 and 8.11 still slow down the GPU when FurMark is detected (see here and here for more detail).
