S.T.A.L.K.E.R. - Call of Pripyat Benchmark Demo

The S.T.A.L.K.E.R.: Call of Pripyat site is offering a non-interactive benchmark demo.  It won't let you actually play but you'll see a snippet of the game and get to test the performance on your machine.  The site was overloaded for me but check your favourite mirror site.
