It doesn't seem fixed to me at all. With wine 1.1.24 and nvidia-drivers both 180.60 and 185.18.14 I still get that unreasonable slowdown in crowded areas (like 4fps in a 25man raid). Normally I have like 50fps. Can anyone else still confirm it?
Should this bug be reopened or should i file a new one?
You should first confirm if this is a real bug...
Let me explain: => WoW, even on Windows has real slowdowns on crowded cities like dalaran. This game basically _does_ not scale. These cities are too small, and most of game cycles are lost in the game code itself (do an oprofile to check it !). Blame blizzard. => The GL drivers on linux are not as performant as windows ones. Bascially they are not threading command buffer generation. Blame ATI/NV !
Have you tried to dual-boot and test WOW in the same box on windows with -opengl ? I did not notice that a huge difference myself. Maybe you will...
Truth is this game does not take profit of multicore, has a sub-par (compared to its DX) GL backend, and that wine does not account for a lot of the cycles (it is just wrapping some FS and GL calls)
PS: remove the VBO disable flag in regedit if you added any ! That's reducing FPS by removing access to modern GL interfaces ! What a bad advice...
