Gold said: When you say "a load, and I do mean a big load" of trees... can you estimate how many tree tokens you are talking about? This is mainly a curious question, there is not a specific number of tokens that is a hard-limit. Dozens of trees might be fine, but hundreds of trees would very likely cause some performance hit. Did you use a bunch of different tree designs, or the same tree over-and-over? (The former would lag even more; the later should help with performance although still could be laggy if there are so many of them.... So if you've used a bunch of different tree species, would you be okay with reducing it to one or two tree-shapes repeated over and over?). Are you using Dynamic Lighting (on or off), and-or Advanced Fog of War (on or off)? If either of these are ON, it can add to your lag when scrolling around the screen. Does your map page perform better if you disable DL and AFoW? Last question, and it may seem irrelevant but, which Character Sheet is used in your game and how many Characters/Journals do you have? Games that have a large character sheet with a lot of attributes, and has a lot of Characters, can gradually become a laggy game, regardless of maps or in addition to lag from maps/graphics. I used 8 different types (6 trees and 2 bushes). I created a (rather large) 'cluster' and then copied/paste said cluster to fill the area. Turning it around here and there for diversity. In total I would say several hundreds of tokens have been placed. 250-300 would be my best guess. Although it will make it look less authentic, for performance and smooth play, I would have no issue reducing the diversity in tree types. I'm not using any light or fog settings, and won't be needing it for the campaign either. No character sheet in use.
