Dust in your PC is a classic problem, and one that Ubisoft has apparently parodies with the computer port of From Dust. The weird little God-game has earned much rage from the PC gamer community, and it's been advised that you stay away from the game until it's been fixed (if it ever is).
Forums, social networks and sites like Rock, Paper, Shotgun have been reporting all sorts of crap, making this one PC port to avoid.
First of all, it features crappy DRM. While it doesn't force a constant online connection, it does require online validation every single time you start the game. Once you get past that, you can look forward to a fixed framerate, poor resolution choices, and a host of glitches. Oh, and no anti-aliasing either, because who doesn't love getting headaches?
Ah, Ubisoft just loves making friends with PC gamers.
