It works with hundreds of games including pretty much every top title and new release. It's one of those things that really has to be seen to be believed. There is also a core following over on Nvidias forums who now have there own technical support team and loads of people sharing settings for things like increasing pop-out and depth etc etc.
I wont lie it does take a tiny bit of tweaking to get each of your games setup just how you wants it but you can store individual profiles in game with a keyboard shortcut. Heres a list of what i currently play:
Stalker Call of pipryat
NFS shift
Colin McRae dirt
Batman AA
COD 4 & MW2
Avatar demo
L4D 2
Race driver grid
World of Warcraft
Deadspace
Tomb Raider underworld
I can whole heartedly tell you that all of them are simply jaw dropping in 3d and it completely reinvents the games atmosphere, Avatar in particular will blow your mind.
this is the current list however there are loads of titles not mentioned so dont worry if what you play isnt listed...
3D Games
Any other questions dont hesitate to ask!
