The thing is, there's just too many items flowing through my tube system, creating a ton of graphical lag. 60+ fps vs 40-60 fps when my quarry is turned on. Is there any way I can put something in the middle of the tube line, so that it outputs stacks of random items when its full? I tried attaching timers to my sorting machines instead of setting them to automatic mode but it cant keep up with my max power quarry. Currently I've been able to solve the problem for cobblestone and dirt, at the cost of two colours in my sorting system and two regulators. Is there anyway this can be done without wasting colours? =P
