(which testers stated to be because of this bug), the largest drop is for OglPSPhong & OglFillTexMulti, their performance was earlier about 2.5x. Interestingly, there was exactly same sized BDW perf improvement around 6.8. - 10.8, which is now gone. Looking at all the affected tests, issue seems to be with pixel shader performance and GPU memory bandwidth.</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> </ul> </body> </html>
