I have a pro membership and I just recently purchased the Lost Mines of Phandelver module. I've been experiencing extreme lag in my games and I just can't pinpoint the cause. I've already gone through all of the Roll20 lag troubleshooting steps and I've scoured the forums but I still can't seem to find the issue. I have a pretty good gaming pc that can handle the load, as well as fast internet. 106mbps DL 10.7 UL average. I want to say that my issue lies somewhere in dynamic lighting/has sight. I went through the first map, cragmaw cave and removed all NPCs, removed fog of war and left dynamic lighting on. After I did this, I didn't experience any lag. I dropped a player on the map and I could freely move the token around with no lag. Although, the night of the game I had 4 players and they were experiencing minor lag. I was just going to drag and drop NPCs as needed for encounters. As soon as I dropped the first NPC in, it began lagging. I took the token out and just dropped one of the free goblin tokens that aren't attached to a character sheet or handout. Just a plain token. I tried to move it around but still experienced lag. I even turned off the grid but I still had lag. The strange thing is, I once ran this campaign but completely created the maps and dynamic lighting manually from the ground up and didn't experience any lag. I've tried A LOT of different troubleshooting methods but I just can't figure it out. I know it's not my pc or internet connection. I want to be able to run my campaigns smoothly but this lag is driving me nuts! Any advice helps.
