Hi, I just purchased the game and I am experiencing very bad FPS drop and lag. I can play BF4 and other very GPU heavy games with no problems, so I know it isn't my computer. Please help, thanks.
Where does the issue usually happen? Campaign? Multiplayer? Zombies? I would perhaps recommend you try to update your graphics card driver and sound card device as well. This usually helps with the performance of the graphics card. Also, BF4 has a different requirements for BO2.
