Hi,<br><br>I am using wine to play World of warcraft (this game is using opengl, and is threaded - 2/3 threads IIRC). I did recently find a reproductable performance regression on versions 0.9.24+.<br><br>Under the same conditions (always difficult to get in an MMORPG game, but this is reproductible), version 
0.9.23 gives me 20/25% more FPS than versions 0.9.24-&gt;0.9.26 (have not tried .27 yet). <br><br>- Is this performance regression known/expected on opengl/threaded applications (new codebase) ?<br>- Is someone using WOW here (and has found a similar preformance regression) ?
<br>- It is worth for me to start looking at it (more measures, throw oprofile at it, bissect the change...)<br><br>Thanks,<br><br>Norbert<br>
