Many players play the game leaving behind several applications running in the background. First things first, one of the major reasons why many players in Blade and Soul have lag problems is due to a network issue at their end. Your game faces FPS drops for two main reasons - either your RAM and graphics card are working inefficiently or you are facing server lag. In a fast-paced hack-n-slash action game like Blade and Soul, reduced FPS can kill all the fun and excitement. When you face FPS drop, your character will be unresponsive to your commands, and the graphics will be choppy and grainy. FPS is one problem that every gamer has faced in Blade and Soul at least once. By PreciousssApril 2, in General Discussion.
