Dynamic Lighting freezing game.

For two weeks now the dynamic lighting in my game seems to cause major issues. Several of my players have dark vision and when they move at the same time the dynamic lighting messes up and lags significantly. This has even caused my game to stop loading and crash.  We play Monday evenings and the game has stopped working both days. It especially freezes to a halt when they all get move in unison causing the page to stop working and forcing a closure of the tab.  It freezes almost all of our computers. I do not play on a potato either so my computer shouldn't be an issue I wouldn't think. 17-7700k GTX 1080TI 32 GB RAM SSD I have removed all the tokens not used. I have also turned all tokens to the GM level, regressed my game to back before it messed up the first time, and deleted all music files. I have also cleared by chat log. I have cleared by cache and cookies.  This issue persist on both Chrome and Opera GX. Some of my players use Firefox and it also happens to them. What else can I do? We have playing this module for over a year now and this website has never had issues but this issue is pretty large for me especially since I pay to use dynamic lighting as a feature and I am pretty sure it is what is causing the issue. 

Check to make sure you are not running Advanced Fog of War and Global Illumination concurrently on the same page. There is a known performance bug with this combinaiton.

I have gone and made sure they are not both on. I hope this fixes the issue. Although, this is a new issue and there were maps with both on that we played on months ago no issue.  As I said though. I have fixed this and am hopeful it works. 

I have insured that  Advanced Fog of War and Global Illumination are not both on. The game crashes less however, dynamic lighting does not seem to be updating in real time and instead is only updating when the character token stops moving.

That is how it should be behaving if you have the option "Only Update on Drop" enabled.&nbsp; From the page:&nbsp;&nbsp; <a href="https://wiki.roll20.net/Dynamic_Lighting" rel="nofollow">https://wiki.roll20.net/Dynamic_Lighting</a> If you or your players suffer from sluggish dynamic lighting render results you might want to consider checking the option&nbsp; Only Update on Drop . What this option does when checked is that the tabletop only redraws the dynamic lighting&nbsp; after &nbsp;a token has been picked up and placed elsewhere on the map. This can lessen the render burden for users running on old computers or when a GM is working with a very large or complex map.

Thank you. This has helped remedy some of the problem.&nbsp;
