The weather in this game causes serious lag for me, and im sure im not the only one.
In places like the Marketplace, or wilderness areas like The Vale, i can barely move around.
I was running a new toon (using this: http://forums.ddo.com/showthread.php?t=269686 ) through Korthos, and it took me forever to move around the village, and the wilderness area. Yet the quests were perfectly fine.
So, once I went through and it went to sunny side, I had no lag whatsoever, which led me to the conclusion that it was the weather that was making me lag.
So I ask for an option to toggle the "weather effects" of public areas and wilderness areas.
