By requiring their new game to be run satisfactorily ONLY on monstrously powerful machines:
(I dont read Russian myself, but the charts are very self-explanatory in English)
The demo is referred to as beta but i dont think this is beta in development sense. The game is gonna be out next month (and if you read this thread overnight, it should be in the same month). I believe 1920X1080 is quite a standard resolution for PC gaming. This is a very disappointing FPS performance I must say, especially considering how powerful the CPU, Ram and HDD (they use SSD) used in the test.
And of course, further disappointing is that it doesn't support DX9/10.
