ATI Catalyst 9.7 (BETA): Three New OpenGL Extensions!



AMD/ATI graphics drivers

OpenGL 3



Catalyst 9.7 (beta version at the time of writing) adds three new OpenGL extensions and continues to improve advanced features such as Geometry Shader (now a geometry shader can access to 16 textures samplers and 4096 uniforms!). Let’s see the new extensions:

  • GL_EXT_pixel_buffer_object: This extension brings the support of PBO (Pixel Buffer Object) to Radeon video cards. This extension is useful because it allows asynchronous texture loading and thus improves texture loading… But Catalyst graphics drivers already support PBOs via the GL_ARB_pixel_buffer_object. So, actually, GL_EXT_pixel_buffer_object does not bring new feature.
  • GL_EXT_provoking_vertex: This extension is used when flat shading is enabled (GL_FLAT). The provoking vertex of a primitive is the vertex that determines the constant primary and secondary colors when flat shading is enabled. This extension is supported in ForceWare since version 185.66.
  • GL_EXT_vertex_array_bgra: allows to fetch a vertex component (mainly color componant) from a Direct3D color array where color is stored as BGRA. This extension avoids to perform the swizzling in the vertex shader. This extension is supported in ForceWare since version 181.00

All GPU Caps Viewer’s tech demos work perfectly on a Radeon HD 4850 + Catalyst 9.7 beta.
