One *simple* step to greatly reduce your lag in Broken Shores
I don't know why it works, but it does. turn all of your options for Audio to off before you zone in. It makes an immeasurable amount of difference, it's one small action with huge results.
I figured this out testing various things as I had a problem with 15 minute zone times into home.
(& of course, there's also the obvious stuff to ease lag : restarting, turning settings down very low - before you zone in)
edit - this works other places too, anywhere you find laggy. Just I only use it for bs/tir grid
