For all my fellow PC enthusiasts, please read on...
I was arragant about my PC - it slaughters every game I throw at it, and I'd be lying if I said I bought this game for any other reason then to see if it was truly the next Crysis, in terms of graphical greatness. For perspective: the core of my rig is comprised of a Phenom II 965 @ 3.8 oc, 4GB DDR3, X-Fi Titanium pci-e, and a HIS 5870. I can run this game at 1920x1080 on Very High settings, with DirectX 11 enabled and AF16 and have it be smooth. But the second I flip AA or advanced DX11 features... BOOM - knee capped. Now that's what I'm talking about - this game is unbelievably gorgeous and I can't imagine what it looks like for the few that can fully max it, including PhsyX.
Ok, moving on. This game markets itself as "Atmospheric" and I don't think I knew the true sense of atmosphere in a game until I first played this last night. It is captivating, unbelieveably immersive and exceptionally intriguing with an entertainment value off the charts. I am so looking forward to finishing this game. It is greatness, and it truly lives up to the hype. Mix STALKER with Half Life 2, maybe throw in a little Fallout 3 and here you go. This is not a game for the feint of heart... I cannot believe how truly scary this game is. More so than any game in recent memory.
So... if your rig can run it, then buy this game. I have a feeling that a future optimization patch along with enhanced drivers will improve performance and also - you really don't need all the bells and whistles unless you're a crazy person like me ;) - the game still looks absolutely stunning at lower resolutions and without DX11, high settings, etc.
Sorry for not focusing as much on actual game content but I truly believe this will now be the game that reviewers use to benchmark high end PC's for a long time coming... considering that for over 3 years, nothing has touched Crysis. Introducing Metro 2033, color me impressed. ENJOY this one folks!!!
