Penumbra takes the cake?

You need a computer the size of a Russian nuclear icebreaker to run Cryostasis properly, so don't try it yet.

I think that's due to bad coding.
Since if you look at Cryostasis, there are lots of other games that have even better graphics, or at least, as good as it has, and they won't need so much from your computer than Cryostasis.
