Red Hat developer Rob Clark, the founder of the Freedreno driver for open-source reverse-engineered Qualcomm Adreno support, has made some significant performance optimizations to this Gallium3D driver.

Freedreno Gallium3D should now be running noticeably faster for many OpenGL games when using the latest Mesa Git code. Rob Clark explained in a blog post this weekend about his latest Freedreno driver addition of resource shadowing and batch reordering.

In terms of the performance impact for this latest Mesa Git code, "~30% gain in supertuxkart (new render engine) and ~20% gain in manhattan are the big winners. In general at least a few percent gain in most things I looked at, generally in the 5-10% range."
