Thanks everyone for the feedback. Obviously these boxes are more taxing to your graphics card than a normal building piece as they each actively display custom graphics. I have personally tested over 200 boxes in a single area without any noticeable reduction in frame-rates, however I do understand that not everyone has the most up to date, high-end graphics cards.

I'm working on an option now to allow individual players to choose to display graphics only on the front side of their box instead of all four sides. This should help those players with less recent graphics cards as it reduces the amount of work your graphics card needs to do for each box.

I hope to have the update ready in a day or two. In the mean time, I suggest people limit the number of boxes they place in a single area if they're having frame-rate issues.
