VTT Performance: What We’ve Fixed and What’s Coming Next

FFR - I'm sorry you had a frustrating time! If you are still experiencing that lag, please let us know your game link (via DMs or Help Center) so we can take a look at that game directly to troubleshoot. The other couple of questions that would help 1) what Browser do you (all) use? 2) did you have dynamic lighting (explorer mode?) enabled? This isn't necessarily going to solve your problem (as Keith mentioned there could be a number of reasons and we'll need to take at your game specifically to diagnose), but there are some Performance settings to play around with to help optimize speed. The "Enable Performance Enhancements" and setting image/lighting texture resolution to lower states might help with one-off situations. FFR said: Keith, Thanks for the pointers. It was that all of us were having the same issue which led me to think it might be an in game or roll20 issue. The game hadn't changed much from the previous week other than adding a couple of maps for a future session so weren't being used yet so wouldn't expect a massive dip in performance. I'll try survey script and see if I can cut a few things out of the game and see how we gen on this Sunday unless England make it to the final in which case we'll have a week off.

Hope your Sunday game worked out well (and England making it to 3rd!)!  In case you ran across lag issues again, please do let me know b/c we would really hope to look at your game. On June 29th, we released Dynamic Lighting performance upgrades (pasting below from our change log), and want to ensure there's no connection. Thus far, we haven't had any negative reports attributed to this change, and users who are using Dynamic Lighting and Explorer mode have commented on the noticeably increased performance! Made performance improvements on the order of 100x to how nameplate visibility is calculated when using Dynamic Lighting. We updated logic from reading pixel data to a shader reading the lighting texture which resulted in reduced CPU load when Dynamic Lighting is on, leading to smoother and more responsive play on the Tabletop. The improvement is across browsers, but Firefox users should see the most dramatic improvements give there is a browser level issue that made pixel data on the browser way slower. Fixed a race condition in Explorer Mode where competing updates would fight over the final display of explored areas. Explored areas now render accurately without lag, artifacts, or unexpected exposures when lighting is set to update live with token movement (i.e., the "update vision on token drop" setting is off). FFR said: Lavi, We always use explorer mode plus the dark fog  and use various browsers. England failed to make the final so we have another session Sunday. I'll see how this goes and get players to look at their settings and all use chrome. If there's any major issues I'll take you up on your offer to investigate the game

Could you send me a DM with the game details to keep it private? We'll start there! Could you also let me know whether you have this specific setting enabled in VTT Settings > Graphics Section > Performance > "Enable Performance Enhancements"?  FFR said: Lavi said: Hope your Sunday game worked out well (and England making it to 3rd!)!  In case you ran across lag issues again, please do let me know b/c we would really hope to look at your game.

What do I need to do to enable you to look at the game ?

Adam, Steverhud and Grusom - I'm so sorry about the challenges you're experiencing in your games recently.   Dean had just published a new thread acknowledging the recent uptick in performance issues and sharing more on what we're doing across several teams to trace and tackle the issues.  This is the thread for the latest information . As they mentioned, we are having every resource possible focused on this effort, and more updates will be posted in that thread with progress and findings. For the moment, that will be the best place to see updates and post your feedback/questions as they come up. Adam Caramon said: The slowness of Roll20, specifically the 2024 sheets, is approaching meme-level.  I have a group of six players trying to create new characters for a new campaign and each drop-down in the character creator is taking multiple minutes to load.  Each player is frustrated with the experience and I have nothing to offer them other than "Roll20 says they know about it, and are trying to fix it, but no ETAs." -Adam Grusom said: My group all experienced bad performance today. Playing d&d 2024 campaign and using the Char sheets, clicking on attacks takes 5-10 secs before being posted in chat.  updating hitpoints is the same.

Loading the 2024 character sheets would timeout over and over again but would eventually load, attack rolls would take 10-20 seconds to appear, if ever. All in all, it was a very frustrating session.
