World of Warcraft - poor performance

view story

http://askubuntu.com – First, i havent used linux for 4-6 years. Im pretty noob to all the new stuff. I have latest ubuntu, with all the updates. And 1.4 wine. I have pre-installed WoW, on my windows partition. Im trying to run it with Wine, but the performance is really poor, and im low on colors. Also getting graphic errors ingame. Im using integrated GPU HD4000 (I5 3570k) Is any tweaking required, or do i have to install drivers..? Everything else is running well on the GPU (youtube, movies etc..) (HowTos)
