Actually - this bugs can be closed wine normally supports smp in WoW And the reason of slow operation is very simple - on Windows - in drivers of video cards - at Nvidia and Ati - there is such section - optimization for specific applications is called"
that you see that in load of the processor - actually is display of ineffective operation of "semaphores" (WaitForMultipleObjects) - from for which the capacity of one kernel on useless a content switches practically is for nothing spent as a result there is an erratic impression that games really normally use many threads
and effective operation 3d subsystems - it will be possible only when finishing a piece of a code - similar to my patch - wine-developers (that hardly) or nvidia/amd (that hardly during short-range time)
my patch became for WoW - and it showed - what method it is possible to correct this mistake - a method the extremely difficult and wasteful
