Guild Wars 2

Does anyone notice any difference between the 2 other than tabbing back into windowed fullscreen is faster and doesn’t need to reload the graphics? I’ve heard that fullscreen is better for fps but I don’t see any difference. Or at least any difference at what I’m currently doing in-game.

i notice that Maps load faster when i am in fullscreen
FPS is slightly better

i sometimes use it when doing fractals and dungeon tours where i have to zone in and out more often
