I've been working on quite the sorting system, which basically sorts every stackable item in the game. I've been noticing a few performance issues when I enter the area (Lower fps in general).
Now I've heard something about covering up all the hoppers to increase performance, since they will stop checking for items on top of them when they have a block placed there. I have read the wiki, but my English isn't that great, and I couldn't make up if this is true or not. Does someone know if this is true or not?
I could try to just cover them all up, but since it's rather large, I'd prefer to know for sure before I cover up 1000+ hoppers
