I'm just coming back to roll20 and ran a game with dynamic lighting for the first time. I've decided not to use "Updated Dynamic Lighting" because of the lack of enforced line of sight but when I turn on Advanced Fog of War in legacy, the game slows to a crawl. I tried this feature on my main PC and my Laptop and Surface Pro, my internet is pretty fast but in every case it lags terribly for my friends and I. Just wanted to know if Adv Fog of War has always been this laggy or am I doing something wrong settings or anything else wise?
