Someone reported the same problem a few months ago: http://forum.winehq.org/viewtopic.php?t=8709&sid=cde338b0c8b0ff3c925808fa6d54209e The suggestion there was "I have the HD4350 card and my FPS got much better when I played the game full screen and inside of Wine with Emulated Desktop turned on. If you have not tried the emulated desktop feature then go into the Wine configuration and click on the Desktop tab to turn on and set the screen size of the emulated desktop. " Does that help?
