A confirmed videogame developer that posts over there from time to time. He has coded for released Xbox 360 titles, and I believe other systems also. I use to know in more explicit detail which games those were, and a bunch of other details the work he has done, but I no longer have my old browser bookmarks which would point me more clearly to that information, and I definitely don't want to go searching it out.
Sorry, but your opinion is obviously highly uninformed when experienced professionals that do this stuff for a living say otherwise. Seriously. To believe what some people are saying, you would have to genuinely believe that game programmers that have been in this business for longer than some people here have probably been alive, don't know what they're talking about. If left with a choice to believe a poster whose knowledge on the subject is questionable (that includes me too. I don't exempt myself) or to believe videogame developers, but more specifically graphics programmers that have done work in released games that people have been able to play and appreciate, I will choose to believe those programmers 10 times out of 10. And that's my final point on the matter, because we've had these discussions hundreds of times by now.
