I got an error before game launched about some physx dll file missing.
Now I'm reinstalling...
EDIT:
It was my mistake. I accidentaly shut down PhysX driver instalation
Game works fine. I didn't wanna play whole demo, I'll rather wait and buy full version and play it 'to the bone'.
My computer specs are aTI x1950GT, Athlon 4000+ and 2GB memory (nowadays it's a minimum for new games) and the game was running at 20-25 fps (played The Witcher with even lower
) with high settings (not extremely high...).
It has great graphics (somewhat unusual).
Can't wait to buy full version.
