keithcurtis said: I meant all characters (PCs and monsters) in the campaign. Hundreds of characters, or many characters with far more than the minimal spells they need at the moment are known causes of the lag you are describing. Not saying that's it, just that it's one of the first things to ask. I appreciate you typing that, keith, b/c it does seem like problems I have been having off and on. Inlcuding ones in asked about in another thread. Last month, I had to run the Gnawbones/Claugiyliamatar map from Divine Contention at 10 ft/sq because it just slowed down way too much at 5 ft./square. With 4 players and 6 pcs. And me. No audio, b/c, well, you know. The experience sucked. The map scrolled and the players could move their tokens, but the game is designed for 5 foot squares. So, let's think about that for a minute. That's a stock image, I have some experience setting up DL, don't use the freehand tool or anything, know my way around Chrome extensions, figured out the invisible token/lighting trick and what not on my own, but.... I am laid low by the inability to realistically have more than 200-300 characters in a campaign. I am encouraged not to use too many spells. Um, what's the whole point of computerizing it then? Again, thx for making that clear, keith. My mini-rant was directed not at you, and I truly thank you for pointing out what is surely the source of my problems, but it's directed at a design that makes using too many spells or too many characters a game-paralyzing problem.
