I love watching the whiners. The pure defenition of "Ignorance is bliss". Guys that haven't even played the title wildly running about like chickens screaming "The sky is falling". And the demo doesn't really count since it had about as much content as a pre-alpha build.
As much content as a pre-alpha build ?
Only two crappy(boring) levels true, but I bet there is little or no difference in a final game for those levels, which went gold a few days after the demo came out. Also the engine won't have changed much in the couple of days between demo and gold.
I think your Ignorance is showing if you think all ( or any ) of the problems and design flews will have been fixed by the time you hand over your cash.
I've just completed Max Payne 2 and Call of Duty, both ran fine and looked good(as does Doom3 Alpha & Half Life2 leaked alpha ) on my GF 2 Ti, Deus Ex2 won't even run without Pixel shaders, so I tried the demo on my work laptop(GF4Go) and boy does it look bad.
The AI in the Deus Ex demo ( and the full game going by reviews ) is the worst I've seen in a long time.
I'm sure the AI in DX1 was better ( I remember being able to shoot people in the leg and watch them try and hobble away, that's all gone now, 2 shots in the face or toe will annoy a 'green' guard, 3 and he'll return fire, 4-5 and he'll die, head or toe )
I won't even mention all the other problems, see previous posts ( Xbox emulation ).
The ammo system is a joke ( same ammo for dart gun, flame thrower, sniper rifle, shotgun, pistol etc ), a joke definitly, but no one is laughing at it.
A throw away game for the kids at Xmas for their Xboxes no more and no less.
Look out for copies in the second hand stores by the middle of January.
