So, I have a confession. I bought Crysis at release, and I even bought Warhead at release, but my PC at the time (Q6600 + 8800GT + 4GB Ram + WinXP + 1280x1024 LCD) just wasn't enough to run it at its full glory. So I shelved the game after playing a few missions until I could experience it properly (i.e. maxed out at 1080p).
I am playing through Crysis now at 1080p, all settings very high, with 8x AA and 16x AF (forced through nv control panel), and I must say...HOLY CRAP. This game is absolutely incredible. The sheer vastness of the maps, amazing combat, great AI...wow!
Now I am seeing the Crysis 2 footage and trailers and am significantly underwhelmed...but that's okay, I still have the rest of Crysis and all of Warhead to complete!
But yeah...I've never seen visuals this good -- and I played Metro 2033 on VH!
