You could: 1) Try turning off Advanced Fog of War.* 2) Ensure that NPC tokens don't have sight enabled 3) Use smaller maps. 4) If you are using Chrome, try Firefox (or vice-versa) * as an alternative to AFoW, you can do what we used to do before it existed: Use light crumbs. These are tokens controlled by All Players so that they share vision. Give them dim lighting only, and place them in rooms where characters have been. You can keep them from being moved by player by using the TokenLock script. Keep the number low, in accordance with suggestion 2 above.
