Hello, there appears to be some significant framerate issues on the Halloween Edition of Grooveyard. (At least for me) Frames will drop from 100 to 70 and even down to 50 on the tables near the bar with no Zeds. Anywhere in that room as a matter of fact in unplayable. The dance floor is better but still not as smooth as the other Grooveyard maps. I don't have any problems at all with framerate on your other maps.

Hope you can address this and possibly fix the problem. The Halloween version is my favorite.
