Chrome Lag

I Generally use Roll20 in Chrome

however yestersay (2/19/14) I started making a table and noticed a VERY high amount of Lag ..
Dragging Images around ... moving Tokens ... anything Just fels like slogging through molassas

I followed the steps to check everything .. extensions etc. and nothing worked

I went and downloaded Firefox .. in a last ditch hope that I would get lucky and I did

it seems there mifght be an issue with Chrome and Roll20 - Im not sure of it ... I just know thats how it was on my PC

I have no issues on Firefox

I'm having the exact same problem. And after reading this, I went ahead and launched my old copy of FireFox (from two years ago). I got a message saying that the browser was not compatible... but it's running it better than chrome is right now.

A few of my thoughts:
Chrome is acting almost as if it's being overburdened. That is to say, every action and animation, is not necessarily working with a delay, but is only processing or updating on a regular cycle. So if I use the 3D dice for example, once the dice show up on screen, they will begin turning to the next side every half second or so, until they have completed their determined cycle (about 10 seconds later) and finally turn to the side of the roll itself. Same with dragging an image or token: every half second, it moves to the next spot on the animation path toward the final objective. All this to say, if roll20 were a stop motion film, then someone has decelerated the film speed until we could see each individual frame lol.

I understand you recently optimized for chrome on iOS and Android, is it possible that Google made an update to chrome that is making it so roll20 is not differentiating between mobile and computer installations correctly? Or could it have something to do with the bit rate and the way Chrome makes its sandbox? I don't know about Brian, but I'm running 64-bit windows 7 if that helps with troubleshooting. Also, I found this problem with chrome to remain even on completely fresh installs of chrome, and on multiple computers.

I hope I was able to help. I love this system, roll20 really is like no other.

EDIT:
The thought did also cross my mind that I might have just been using images too large to support, but this problem persists even on a blank map with only a grid and one token.

A few things to check: Does the campaign you're working with have a long chat log? Are there many pages with lots of images? Are there lots of journals and/or handouts? Any of those can slow things down. The GM should consider clearing the chat log or archiving pages/journals/handouts that aren't currently in use.

Is there a chance that any of those might be true for the campaigns you have tried?

Thanks for the speedy reply! :)

I have no chat logs to speak of (3 entrees past the default I believe). I realize I have a couple of larger images, but not too large that they shouldn't be manageable as they are all .JPG (don't know actual size at the moment as I am not at home, but I ran them through photoshop to drop the quality and make sure the size was down)

I'm on my chromebook right now, and it would seem that the problem is now only happening when rolling 3D dice even on a brand new (and completely blank) campaign that I created. I used to be having the same problems on my chromebook that I had on my desktop, but seeing as everything but the dice seems to be working on my chromebook now, I will submit an update on how it's working on my desktop as soon as I get home.

Edit to be thorough: my main campaign has not had any sessions played and is still in development. So it only has one journal, no handouts, two maps, no scripts, no tables, no extra decks, 4 custom images, less than 10 jukebox items, larger map has a hex grid 7-10 tokens, smaller map has dynamic lighting and one token on a square grid.

Update:
I notice you have now disabled 3D dice for chrome with an explanation that my browser does not support OpenGL... I did not know that. And now at home I'm not having delay with anything else except for when I scroll the map while logged into the same campaign twice (one as DM and one as player so I can be sure what players will see.)

Seeing as my second login is from the same computer, on the same browser, using the same credentials, and just simply in another tab, I should honestly just be happy it works at all given the opportunity for conflicts there. That said, everything meaningful seems to be fine now, and I appreciate the assistance.

3d dice is not disabled for Chrome, it is probably an issue with your OpenGL. Please go to https://wiki.roll20.net/Solving_Technical_Issues and follow steps 2 and 3. If that does not help please follow step 4.
