Though I don't actually experience these issues others are having, and that I like the map, I can see how it can be affecting others with how much is actually in the map. The various effects to create the ambience in the building can cause some frame drops if the player approaches them.
I'd rather keep the saloon but if its causing the majority these issues then, though I don't want to say it, it probably should be removed from the rotation until FPS drops are removed or fixed.
