Just tried the PC demo. Looks very nice I must say, but I can't play it longer than 2 minutes.
After those two minutes, the image freezes, ten secons later, the screen goes black, then i get some artifact screens (scrambled pink and yellow colors) and some black screens. If I don't ALt-Tab out of the game then, I have to restart.
After such a crash, I can't start the game again; "Failed to initialize 3D engine" it states.

My computer is an Acer Laptop, Aspire 5024.
AMD Turion 1.8
X700 Mobility 128 MB with recent DNa Drivers
1Gb ram
Win XP Home

Any help ? I liked what i've seen up till now, so i'd like to actually play the demo mission.
