I've found that this mod is very demanding even at lower graphics. I'd often find my GPU at 100% at 30mins to an hour.
I have a ROG 3080 10GB, and noticed my GPU at 100% and reaching temps of +85C. The spike in demand is typically while in an instance like the Arena, towns, or during battle... however, when accessing areas like the Arena and especially the blacksmith, my GPU usage and temp skyrockets.

I understand it being demanding when tons of people are moving + lighting & shadows, but the smithy shouldn't be as taxing as the rest and sometimes worse than being on the battlefield.
Has anyone else encountered an issue like this?

Also note that I tested this in Vanilla, my GPU didn't get past 60C at max settings.
