    There is virtually no difference in what is accelerated by hw or not since shader is the norm ie since dx10 GPU or since nv50 or r600 if you prefer.

    Nor there is secret command on AMD GPU, anyone...

    This mesa demo fill probably have double perf with 2d tiling on (depending on the GPU has the high end GPU benefit more from 2D tiling)

    YOu won't exhaust GPU VRAM bandwidth with 1 big texture. You really need to push the bandwidth requirement to clearly see 2D tiling effect. 1 Big texture is not a test stressing the gpu.

    They did not release the driver, there is absolutely no driver code in what they released. It's just header and some egl/glx glue code. Things that have been public for ages.
