I enabled KHR_debug to find the cause of some bugs in my app, but became interested in performance-related messages that were getting printed. Example: > Multi-LOD fast clear - giving up (2048x16x11) I'm interested in improving my code to remove such warnings, as all extra performance is welcome. But I understand most of those messages only partially - e.g. in the above example I understand what it means, but not what might cause it or how to fix it. Is there any documentation on such warnings? Note that I'm mostly interested in the warnings produced by the *Intel* driver, as I'm using an Intel GPU. </blockquote> Which version of Mesa? I can't find any occurrence of "Multi-LOD" or "giving up" in the current Mesa code base. -Brian </blockquote></div> </div>
