Here is my World Of Warcraft config, I can run World Of Warcraft easily, with just a bit of lagg in populated places, You might want to configure the resolution and ENGB:
SET gxResolution "1280x1024" SET gxRefresh "60" SET hwDetect "0" SET movie "0" SET readTOS "1" SET realmList "eu.logon.worldofwarcraft.com" SET gxMultisampleQuality "0.000000" SET readEULA "1" SET readScanning "-1" SET realmName "Turalyon" SET gameTip "16" SET gxCursor "0" SET SmallCull "0.040000" SET frillDensity "32" SET farclip "357" SET Gamma "0.600000" SET MusicVolume "0.60000002384186" SET SoundVolume "1" SET SoundOutputSystem "1" SET SoundBufferSize "150" SET MasterVolume "1" SET ffx "0" SET AmbienceVolume "0.60000002384186" SET uiScale "1" SET mouseSpeed "1" SET cameraPitchMoveSpeed "90" SET cameraYawMoveSpeed "180" SET cameraPitchSmoothSpeed "45" SET cameraYawSmoothSpeed "180" SET cameraSmoothStyle "0" SET cameraSmoothTrackingStyle "0" SET cameraDistanceMaxFactor "1" SET SoundZoneMusicNoDelay "1" SET gxColorBits "24" SET statusBarText "1" SET gxApi "opengl" SET ffxDeath "0" SET minimapZoom "0" SET guildMemberNotify "1" SET profanityFilter "0" SET readContest "-1" SET gxDepthBits "24" SET expansionMovie "0" SET locale "enGB"
