yea, figuring out what is visible to a player is pretty tough mathematically. I wouldn't expect it to work well right away considering there are only a couple devs on it. They probably just drew a vector from one player's vision source to anothers
You could also save money on the processor and get the 6300 instead of the 6350. 3.5x6 should be fine depending on what you do
is this only for gaming?
