So its a no go in Win7 x64....couldn't get it to work whichever way i tried...
It could be due to the x64 bit-ness of the OS...

Isn't there something about driver signing in x64 that isn't in x86 version...?
Is there any reason at all for a gaming machine to be in 64bit instead of 32bit ?
Considering that 3Gb should be fine for just about any game for a while, and that 32bit games should be around for quite some time....

I also tried playing a few games off steam, and stalker clear sky i could get in to set it up,, but couldn't choose DX10, and after validating, it craps out everytime i run it with an xrayengine error..
Bioshock seem to only run with a less than optimal screen resolution, with part of my desktop still showing...
Left4Dead works fine.
NFS porsche2000 doesn't work properly, but then again its ancient.

I just ran the steam exe from the XP installation, so it may be due to an improper install, even tho it updated 4 games when i ran it under Win7 x64...
