Frame drop is on your end, and depending on what causes the drop, it may or may not affect internet connectivity. Is tabbing away from Graal supposed to affect framerate or something? I've never actually experienced any issues at all, except if I walk by Burger Refuge. I thought most people do tab away when they wait to spar, I do it pretty much every time.

Although, the Facebook client itself can be slow depending on what else is happening on your computer. Perhaps that may be part of you experience. Similarly, I know my Graal v6 client drops frames when I have my email program open, and I assume that's because when the program is open, it constantly checks for more new mail. So I can't play Graal and check my email at the same time.
