If you are running Titanium client, you may want to try using WinEQ and see if that helps. Otherwise, I would suggest maybe trying the SoD client if possible, as it has most of the WinEQ functionality built in and handles multi-boxing better.
You may also want to try updating your Video Card drivers and/or make sure you have the correct version of DirectX.
Another suggestion would be to make sure you don't have a multi-core CPU issue, which is discussed in the FAQ in my sig.
