I know I shouldn’t need to say this, check your settings in game. I started to play with my settings and noticed a dramatic improvement, still lagged with particular moves taking eons to perform. I can say it helped with a lot of the screen hop, though the occasional stutter/glitch happens. Just giving everyone a heads up on what has worked for me. (My usual settings are not what I use in BFN)
This helps very little for most of us, it's a bandaid at best, and while your heart is in the right place here, the performance is unacceptable. Even on low settings with good hardware, PvP is a slide show.
