I'm boned. Bioshock has been out for almost 12 hours now, and I can't even look at it. Larry doesn't support Pixel Shader Model 3. Using the latest valVe hardware survey as a source, almost half of the machines out there do, so I can see why you wouldn't hesitate if you had to make a choice. Of course, slightly more than 1/3 of respondents are in a similar boat as me.
Oh, well except of course that Larry is a desktop replacement. He can't be upgraded. He can only be replaced. And I'm not going to do it. Yes, I will now see more games come to market which will be unplayable on Larry (and yes, Bioshock is unplayable - it renders most of the scene as black). And it will build to a critical mass. But I'm not going to replace a $4000 desktop replacement because of one game.
Even if it is going to be the game of the year. Which is going to get spoiled for me. Because I won't get to play it before somebody spoils it.
