The most common cause for Lag in game that we come across is data loss or latency on the connection. As such, if you’re experiencing lag in-game we recommend you first try to connect on a different network (if possible) in order to rule out the possibility that this is the case.
If you are successful in connecting on another network without experiencing any lag, we recommend you attempt to bypass your router and connect directly to your modem as a temporary troubleshooting step in an effort to rule out potential router problems. For assistance with this, please reference the KB article referring to this procedure here.
In-game lag can sometimes be caused by 3rd party programs interfering with the game client. If you experienced the same amount of lag on a separate network we recommend you try disabling all 3rd party programs to see if it has any effect on your issue. For instructions on how to do this please reference the KB article here.
Disable AV/FW Software
We’ve also seen an array of security software interfere with the in-game connection as a cause for lag. If you were unsuccessful with the MSCONFIG procedure, we suggest temporarily disabling or even removing security software to see if it has any affect on the issue. We do not, however, recommend running your machine without a security application. Please only disable or remove security software as a temporary troubleshooting step.
