Arty in spawn exit is pretty boring and not personal enough for me. But it is a good way to leave the server since you're going to get booted for having 3+ kills. But it's better to maximize misery of the enemy team + griefing someone on your own team at the same time, at least that's my preference.
And yeah, any PC gamer kind of knows these things, I suppose that is god vision to the uninitiated like yourself. I mean it's kind of expected since every AAA title has bugs in it from Rage to Dragon Age to RO2 to Skyrim. If you played the beta you would also know that specific settings do hilarious things and if you read the patch notes you would know that specific settings can be exploited to make the game easier (most have been fixed I think?). So, it isn't much of a jump to extrapolate the fact that, yes, some settings might cause disruption to your game play experience.
Basically, PC gaming does require a modicum of PC knowledge. No offense, but arguing that with you is pretty silly and it is akin to me trying to prove to you that 1+1 = 2 on a non-abstract sense (there's actually a giant proof somewhere written in the late 1800s, I think, that proves 1+1 = 2).
