1.First of all, check your PC specs and compare it with the minimum requirements of this game. If your specs falls into minimum, then expect lag on your part.
2.Check your internet connection.
3.Do not mixup your Youtube viewing,Facebook gaming and Torrent downloading during online gaming. Such activities eat up a lot bandwidth.
4.If your using Vista/Win 7, set your themes to classic. DWM.exe is a program that manages the appearance of your desktop. IT EATS UP A LOT OF RAM. If your
PC cannot handle it,better settle for an old win2000 appearance.
5. Try to use this -> http://www.wowinterf...LatencyFix.html Worked for me.
6. Try to lower your ingame graphic settings. The lower it gets, the better gameplay. Try to use FRAPS to see your actual FPS ingame. 45~60 is playable imo.
7. Change channels frequently. Find a channel that you think is best by observing.
8. Last tip,BUY A NEW COMPUTER IF YOU CAN.
Tweaking your system should be a last resort, and should be done by knowledgable persons.
