One question? what does that have to do with FPS?
nah anyway, ur ping? it's caused by the server u join combines with ur own internet connection, to get a better ping, join dedicated servers and get a good internet connection like DSL or Cable or Wireless.
And if ur talking about ur fps... go see the help section, lot's o threats there, and no groovy i will not link it, it's just 2 clicks away. (resp. General, then HELP)
