BioShock Demo Tonight

From The Cult of Rapture comes word that at 7pm EST tonight the PC demo for BioShock will be released for all to enjoy. It will be a hefty download at 1.84 GB and the post suggests everyone to update their graphics drivers to the latest, which will coincide with the release of the demo. The driver update will offer a performance boost.
In a more recent post, Ken Levine from Irrational Games (now dubbed 2K Boston) has posted on the 2K forums, urging players to refrain from spoiling the game for others.
If you’re going to buy the game this week, I highly recommend you stay away from any forums that might have spoilers until you play the game through. Our goal in making the game was to thrill and, often, surprise you.
Please don’t ruin other people’s experience by revealing secrets in unmarked threads, and if you want to enjoy the game to its fullest, stay away from any threads that might ruin the fun for you. With a game like BioShock, it will really make a difference.
