As some non-OpenBenchmarking.org news this weekend, committed to the mainline Mesa Git repository for Mesa 7.11 is support for OpenGL instanced drawing within the ATI R600 Gallium3D driver.
Instanced drawing support is not new to Mesa in general but last month there was instanced-draw support merged into Mesa
for the GL_ARB_draw_instanced and GL_ARB_instanced_arrays support as part of the (slow) OpenGL 3.0 support upbringing. With the commits over the weekend, Christian König implements instanced drawing support in the R600g driver.
The OpenGL instanced drawing for this Gallium3D driver comes from this commit
touching around 200 lines of code.
