  And where's the 64bit Far Cry part of the article ?... That could've been quite interesting as well..

  19: That's the whole point: WoW is an interface that allows for 32-bit applications to run on the 64-bit OS. AMD64 supports a mode where 32-bit applications are run concurrently with 64-bit applications under a 64-bit OS, but you still need to have the 32-bit interface that the old applications understand, and that interface then ties into the 64-bit OS.
  
  I'm not sure what Pjotr is thinking when he says that you can run 32-bit drivers under 64-bit Linux, though. In my experience with Linux, you need to compile practically every driver/application/utility to get it to work, which of course gives you 64-bit drivers under 64-bit Linux and 32-bit drivers under 32-bit Linux. It's just like Windows: the drives and the OS need to be 64-bit, while you can have a compatibility interface to run 32-bit applications.

  Pjotr: I didn't think you could run 32bit software while running within a 64bit OS (which would be using the processors long mode). If plain 32bit software could be run without WOW, why would M$ be making it?

  My only point is that (in my opinion) until EVERYthing is out of beta, any performance data that comes out is completely worthless/meaningless especially in a field as finacky as graphics performance.
  
  As such, deducing ANYthing from worthless data is in turn, itself worthless and futile.

  #11,
  The Linux distros have not all come as far. Some are better at AMD64 than others.
  AMD64 also allows direct hardware 32 bit execution, unlike the WoW, so you can run 32 bit drivers in an AMD64 64 bit OS.

  Anemone, these are beta drivers, you have to expect the performance to not be as spectacular as the stuff the companies already know (x86-32). And we also have to consider that these results are using yesterday's cards; 64-bit NV40 and R420 should be a great deal more satisfying, especially if paired up with improved drivers. I imagine that nVidia's driver team experience will produce something approaching x86-32 performance by the time XP64 is ready to roll, with ATI pushing out its final beta around the same time; but, what do I know about programming, I just play the games and moan when they don't work right. ;)

  Looks like there is a lot of improvement before they are going to impress gamers...

  At the risk of engaging the wrath of all the Linux fanboys out there, let's just point out that running the latest 64-bit Linux distros right now is perhaps even worse than XP-64 beta in many areas. Sound support is severely lacking, as is 3D accelerated graphics support. Text mode and unaccelerated X work fine, although they don't show massive performance boosts. Still, with sound and graphics support being a difficult proposition for all but the best Linux hackers, 32-bit is still the way to go.
  
  This, by the way, is based off of personal experience with trying to run Linux on an Athlon 64 3000+ system. 32-bit Linux is running happily now, although with the 2.6 kernel I still can't get Nvidia's drivers to work. I'll try 64-bit Linux again in about three or four months, I think.

  And WOW is nothing new just so you know. If you run a 16bit app in 32 bit Windows XP you will see WOW in your process lists with programs running in it tabbed out a space.

  The differences between Nvidia and ATI arch when computing 64bit wont really be known until we have 64bit games to look into.
  
  WoW = Windows on Windows. Think of it as a 32bit emulator. Since Win64 its a native 64bit OS, WoW allows you to run 32bit programs by wrapping or emulating the 32bit calls made by the program into 64bit calls for the OS to understand.
