Do you REALLY have the slightest clue what you're talking about?
I knew some smart butt (thanks swear filter) would say that.
Do you know?
It's not my job to optimize games. I'm great at what I do, and people expect me to be. Guess what happens if I do poorly? That's right, I get fired. It's not asking much to expect a multi-, multi-million dollar company to show some proficiency.
If I'd never seen a well optimized game, I'd reasonably conclude that it might be prohibitively difficult. But, since most games ARE well optimized, and this is a consistent issue for Beth., then until proven otherwise, I'll logically assume that it's not difficult, it just requires work (Which Beth. seems to dislike.)
