Demo v the Real Game?

[Pavilion]

Ok! I have downloaded the demo for Deus Ex: The Invisible Wars. It was very nice and I enjoyed it. My question is how does the demo stack up with the real game. Are the graphics the same or close to the same? Are the levels much longer or, if not, are there a lot of levels? Right now, I can get this game at Best Buy for about $30 and I think that I will but before I shell out that much money (LOL, yes, that's a lot for me :-) I want to make sure the demo is, in fact, an actual representation of the game.

Also, my system:
AMD Althon 64 3400+ @ 2.2 GHz
256 MB DDR 400 RAM
Xtasy 9600 XT with 256 MB DDR RAM @ 526 MHz
40 GB Seagate 7200 RPM Main Hard Drive
200 GB Seagate 7200 RPM Secondary Hard Drive
Microsoft Windows XP 64-bit Edition

Will Deus Ex: The Invisible Wars run fine on my system? The demo runs fine so I am assuming that the real game will run fine on my system and my computer does meet the minimum requirements but there are so many psots about system incompatabilities that I just want to be sure.

Also, since I'm posting in here, when I run the demo with high quality shadows I get little gray dots on people but when I turn the shadows down to low they disappear. Does this also occur in the real game or is it jsut in the demo?

Thank you all for your time.

If you liked the demo you'll probably like the full game. Graphics are basically the same.

The level size in the demo is probably average, but there are about 50 of them in the full game, as opposed to 2 in the demo.

If the demo runs on your system, the full game should. That grey dot problem is present in the full game for some people. I'm not sure if it's been solved with a patch or a driver update yet ...

Ok! Cool, I jsut installed the latest graphics drivers for my video card but now the demo crashes on me when I boot it up. It's ok, though, because Windows Explorer is also crashing on me so I jsut have to reinstall Windows, again. (I should stop tweaking my programs, I guess. :-) If I can I'm gonna get the game tomorrow, then. Thanks for your help, Random!
