I have Vista 64 and the game works better than...eh something :P

Haven´t tried the Tech Demo but it will probably work too.

Good that it works for you ( i see you got a very new card). I got a 8800gts (512MB , g92 chip) which isnt that old (renamed to geforce 9xxxx afterwards) so, anyone any clues why the last generation of geforces dont play the tech demo / game under vista 64-bit ? Thx.

btw, did i mention that the latest nvidia drivers r installed ?! I guess not :P

I had 8800GS (384mb, g92 chip)
Demo and game is work for me under vista64.

yeah, with "beta" drivers... should work with standard aswell.... but it doesnt.

Last generation is 200 series. ;)

Of course ;)

sorry my mistake, i tend to say "latest" on the actual series (which would be the 200) and last as the previous one. Sorry again.

There is a pacth that allows you enable to enable very high settings of Crysis on xp! I try it and i was able to play crysis on dx 10 settings on xp without need vista and dx10. But the game run very slow even on high settings on my machine so i was forced to set physics to low and some effects on medium to be able to play. But i read on some forums that Crysis very high settings run faster on xp than vista, so i would like to know will there a pacth like this in the future for cryostasis that will unlock the dx10 graphics/effects for xp?? Please dont limit only to dx1o just to force us upgrade to vistta!!:):):)

But I think Crysis is the only game where you can do that. I saw a video on youtube where a guy had the same graphics card as me had 10 (!) fps more maxed in XP, that means 25-35 % better.
