Execlists is in no case faster. It's ~50% slower in GL context re-creation test, and in other CPU bound tests it's 5-10% slower: - Batch5-7 (batching huge triangle strip with ever increasing number of draw calls) - DrvState (mostly CPU bound GL state change test) - Multithread (GL calls from multiple threads) Same difference both on BSW & BDW.</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>
