Tips on improving performance in browser

Hello everyone, I have a very large map with dynamic lighting.  I am worried about the performance as it loads slowly for me and lags quite a bit. I was wondering if there are any tricks or ways to improve the performance so it doesn't lag so badly.  So far I have done the following: -Took screenshots of all the background assets and stitched them together.  Then compressed the new image file. -removed explorer mode -reduced the size (from 500x500 to 445x321)  this was the most i could shrink it for it to still work. -I tried to use as few dynamic lighting objects as possible to make it work. Thank you for your help, I know some of my players have had lag issues in the past with large complicated maps and this one is particularly bad, so I want to get it as smooth as possible

get rid of all NPC visions and forget about anything that's coloured in lights. Aura/Tints makes it quite laggy, though i find that using only auras is bearable. Regarding the npc visions, even if they don't seem to have vision, i encourage you to open each npc, turn vision on, and then off again. In Dead in thay for example, most of the npcs have vision turned off, but if i put a light source, it appears as beeing seen, so i have to open each and every npc, turn vision on, and then off again. Using a macro for mass turning vision on or off doesn't help in my case.

You can also try using Daylight Mode if light source placement is not critical. Also, set the page to update token vision on drop.
