is this mod performance-intensive? if yes, is the load more cpu or gpu oriented?
It doesn't really eat up performance at all, from what I've experienced.
My pure thief just got his first encounter with a random dragon in riverwood earlier today. I'm lvl 36, and even though it was an elder flame dragon, it still managed to wipe out the Whiterun guards with ease. And me, being without my companion and unable to sneak attack at all, got blown to smithereens as well. This is the first time I've ever died to a dragon, and it's all thanks to this mod!

Great job, and hope to see the other dragons soon!
