Yes, that square area is intended for setting the target fps to a lower amount when entered, I do that because of the weird dream I had before, which I was armed with a weapon and being outside of the large house become so laggy that anomaly didn't catch up, but when going inside of the house, that anomaly was so fast that I didn't get enough to react and it charged at me so that I woke up and almost screamed.
Appreciate your comment on this!
