When i play medal of honour pacific assult online i get very bad lag in most servers i join. Its really reaaly really bad lag the worst ive seen in a online game. The games runs really smooth but the lag is so bad i cant play online.
In every server? When you join a server that you have a low ping on Hit TAB i think and look at the other players ping, and see what there lagg is. I have joind a BF2 server with a ping of 36 or so and it lagged to hell because 5 other players had 175 to 250 ping.
If thats how low your ping is then its prabally not lag from your internet connection, turn ALL video settings to LOW and see if it still lags. Just try it, no matter what your video card is.
