To elaborate on your last line; there's a bunch of factors that come into play, put in mind that OVER half of the globe's population doesn't have a decent connection and the same can be said about a decent PC, most weebs that play this are on their high school days or have a job, it's not about the efficiency of your plan or the dpt you output but a combination of all your factors which you seem to be neglecting.
