Neither BDW GT2 nor BXT perf changed. For other things I don't have data. (GfxBench Manhattan tests perf has improved on BXT sometime since mid-July, but I don't have data on whether it's due to kernel or Mesa.) (*) ZBuffer text draws a lot of trivial triangles on top of each other, so it tests depth read/write and render write bandwidth + draw overhead.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
