I would really like to see a benchmark of the Xeon Phi on LLVMpipe

The original Intel Larabee would have had a DirectX translation layer and this project could be seen as an OpenGL version of it.
Just loading a distro with Gnome 3 running on LLVMpipe or benchmarking some ioq3 and iodoom3 games would be VERY interesting.
From the first Google result for "transform feedback" (http://www.opengl.org/wiki/Transform_Feedback)
From the article:Quote:
Transform Feedback is the process of altering the rendering pipeline so that primitives processed by a Vertex Shader and optionally a Geometry Shader will be written to buffer objects. This allows one to preserve the post-transform rendering state of an object and resubmit this data multiple times.

OpenGL Transform Feedback adds in the capability of altering the rendering pipeline to allow for primitives processed by Vertex/Geometry Shaders to be written to buffer objects. By writing it to buffer objects, the post-transform render state of an object can be saved so that it can be re-submitted multiple times.
