EDIT: SOLVED : I turned hardware acceleration on and this has fixed the issue. I've noticed a slowdown on some of my big maps that use dynamic when using Chrome. This issue started to occur withing the last two days. Dragging and moving the map stutters ( Example ). The slowdown is not present when using Firefox and is fixed in Chrome by disabling dynamic lighting. I am reporting this because these maps were working fine a few days ago, but are laggy all of a sudden.
