Using Chrome and my campaign chat log is clear, no dynamic lighting, I am using 3d dice, my game has barely anything in it. We basically use it for background noise/scenery. Only extensions I use are Avast and google docs. My PC has 8gb of ram, a gtx 970, intel 2.8 quad core, running windows 7. I switched over to the basic pathfinder sheet and it runs super smooth so I'm just going to stick with that, thanks for the reply though.
