I still do not understand what having multiple layers of electronics on will cause lag. It seems very possible with enough optimization and work. Also ax a side note. The screen should not rotate as a cube but use a button to switch up and down layers. Once again. I say its a very good suggestion, but idk if it is added or not. Also I never get FPS drops on my pc. We need to move forward sooner than later and start forgetting about computers that run XP and have 2 GHZ or less CPU's, as more and more people are getting better computers
