Lags when map rendering

I bought the Dead In Thay addon. When I try to load any map from this addon except starter page and doomvault map my browser goes mad and begins to lag awfully. The only way to load thr map is to zoom out before black loading screen disappears. But if I try to zoom in already loaded map (with tokens, lightninh etc) lags starts again. I tried to turn on/off dynamic lights but with no effect. Is there any way to fix this?

I'm sorry to hear that you're having issues with this addon. Could you please carefully work through the first three steps of our guide to Solving Technical Issues ? Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions and anti-virus programs. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) Thank you!

Well, for some reason Firefox works better and shows no lags. Thank you for your advice! Problem solved
