I find that as long as it is under 500, it's playable.Also choose the right server entry point at the server selection menu in game.Eg. Epic 1 and 2 is 250 for me and Epic 3 is 300+
u might be having lag...or FPS issues.sometimes i have 600 PING and im lagfree.i would suggest you to reboot your modem, check for useless programs u might have in your computer such as:cleaner (those dumb programs on ADS that say they clean your computer...they only screw u up more)bing bars, radio bars, google bars...pando media boosterchrome..also reboot ur computer after each modification.
