Well, my PC isn't state of the art, but it ran the game pretty good, at ~30 fps in 1440x900 with all graphics at their highest.
I got past the first stages of the game, until certain point with involves jumping from place to place in a flooded basement, that place scares the shit out of me and I haven't played ever since.
I gotta admit that the first time I played it, I pirated it, until this recent Steam sale, I got it for $9 and I'm glad I did, even if I'm still scared to go on. (you can check my steam library if you don't belive me)
Can't wait to see what Frictional Games are up to now.
Just for the record, I'm planning on finishing this game... sometime... I played and finished lots and lots of survival horror games, like Resident Evil from 0 (zero) to 5, I remember back in the PS1 era, I had a demo disc showing Resident Evil 2, I bought it and I never played past the police station. Fast forward a couple of months or years later and I finished the thing like 5 times. Same with Silent Hill, too scared at first, then some time later, finished it like 4 or 5 times. Someday I'll certainly find the courage to keep playing, but right now, I'm scared shitless.
