How do you get rid of lag glitches on combat arms

Lags and apparent glitches are more the result of the user's own network setup rather than the game or gaming server itself. There is always a video lag between a game console and a monitor or CRT. All games require that certain ports be open for proper PC-Server or game console - server communication during online play. Port Triggering or Port Forwarding is the only way to deal with this problem.

Many new HDTV monitors (in particular Sharp Aquos) have installed gaming circuits that automatically remove the video lag between a console the monitor, which can be as high as 100ms.

Router Quality of Service (QoS) setup is also a key element in gaming speed. All network processes compete for Router access; QoS allows the user to prioritize gaming or application data so that the data has priority access to the Router, and hence the gaming server. Without it, the game data is just one request in the Router access queue. If you're running programs with automatic updates, it also slows the network, as those processes are constantly accessing the Router looking for potential updates.
