Our other options are Meta or BLORP. We're generally trying to move away from BLORP, so my preferred solution would be to improve the Meta path. (As an aside, it looks like _mesa_meta_DrawPixels doesn't think about MSAA either, and maybe it needs to...) It looks like _mesa_meta_DrawPixels is interpreting ClampFragmentColor == GL_FIXED_ONLY stupidly, and thinking it needs to go through a float buffer when it doesn't. Fixing that would speed this up by around 20%.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
