You are an extremely confused person Batman. First, you don't know the definition of a fanboy, because you used it in the opposite context of its definition. In fact, one might be able to apply the word to you in this situation.
When shit doesn't work right, you say something. When you feel a game doesn't play well, you say something. When something doesn't live up to its hype (and it rarely does), you say something. Such is life. If the game runs flawlessly for you, more power to ya! But if it doesn't for others, what does that have to do with you? If you're not willing to help figure out why, how about you shut up instead? Don't like me telling you that? I guess you understand the feeling now.
By the way, Doom works fine for me. Weird.
