Recently I noticed that the Beta PoV setting in the command line no longer makes a difference. It looks like they made the wider PoV the base setting now. In general I do like the wider PoV, however I have one unit I ran in the lower PoV view as a narrower PoV is less demanding on the computer. (~10 fps with my one unit)
I wanted to give a heads up to those that say “Since patch such and such my performance has dropped”. In this case whenever the PoV standard was changed, you did lose FPS because of that, it was a choice Anet made. I’m not sure anyone has surrendered that as a reason why you dropped frames.
