Tons of graphical lag, stuttering, etc. when 3 or more people are connected at the same time.

I'm in a campaign with five players (counting myself) and the GM. When all 6 of us are connected at once, the game is nigh unplayable. There doesn't seem to be much server  lag, but any way I interact with the map is extremely laggy. If I'm connected by myself, there's very little to no lag. I've also gone through the "Solving Technical Issues" wiki article to no avail; there don't appear to be any extensions causing problems. I even double checked by trying a different browser than the one I usually use. I've tried closing all unnecessary tabs and other resource-hogging programs on my computer. I've disabled 3D dice and gone to voice-only for broadcast and receiving, and done anything else in the settings that seems like it would help, but the problem persists. I did a bit of digging in the old threads on this subforum, but I haven't yet found anything that seems like it would fix my problem. My computer isn't exactly a bleeding edge gaming monster, but it's not ancient; I run most games no problem, so it seems like a web app like roll20 shouldn't be an issue. Here's the deets: Operating System: Windows Windows NT 10.0 Screen Resolution: 1680 x 1050 Web Browser: Chrome 52.0.2743.116 Browser Size: 1680 x 987 IP Address: - Color Depth: 24 bit Javascript: Enabled Flash Version: 22.0.-1 Cookies: Enabled

There are teo things that I noticed that slow down roll20 dramatically: large maps (large pixel dinensions) and complex dynamic lighting setups (with lot of details in the DL layer). For example my first wirld map had roughly 4000x3000 px - and it was terrible to use it.  So how does your current page look like? Big or small? Dynamic lighting on or off? Maybe that could give us a first hint. 

No dynamic lighting, but I'm not sure how big the map image is. I'll check with the GM and see if he can maybe shrink it.

Kristin, it's  Haushalter 's Tenra Bansho Zero game. Thanks for helping us look into it! 

Out of curiosity Kristin, what is the the tipping point where journal entries start to cause load bloat?

Thank you, that's good to know. I was more worried about my ridiculous number of rollable tables (although my library of monsters/npcs is nothing to sneeze at either).

Kristin C. said: The next time you're in the campaign and hit a lag spike, try to grab a console log for me. It could be you're hitting some errors. Another thing to check is to make sure roll20 is whitelisted on your anti-virus software if you have any running. It's not really lag "spikes". It's a solid wall of continuous lag. I can also say with some certainty now that the lag is due to the audio/visual component of the game. When there are no other users logged in to the game and webcam/voicechat broadcasting isn't active, there's no lag. When there's one or two besides me, there's some lag. And when there are three or more others, my computer is pretty much unusable. And get this, when the voicechat crashed in our latest session, the lag went away completely and pretty much instantly.

I just wanted to add in that I too have experienced graphics lag by sound in game, I played something in the library for about 2 hours while I was building dungeons and testing the auto play sound track as I switch(about 7 background maps each with its own auto play music), then finally worked on the 8th map while having a piece of music on continuous play, without anyone logged in but myself, and suddenly noticed lag as well(first sign of notice was the ping circle moving in a choppy fashion)

I would like to state that I have had the same problem and until now just chalked it up to logging in from an older laptop. We actualy have gone to using skype for our voice chats because the problems with the integral chat types were so bad.&nbsp;
