crysis is a 32bit and 64bit dx10 and dx9 game

Hellgate London

Company of Heroes latest patch supports 64-bit.

There are a few more out there if you poke around.

-A.

All Games for Windows branded titles will run on 64-bit versions of Windows
(at least Windows Vista x64), but that does not demand they provide a 64-bit
native version of the game.

Company of Heroes isn't a 64-bit native game, but it does take advantage of
the "Large Address Aware" feature of 32-bit applications. When run on x64
versions of Windows, this doubles the possible memory addressing from 2 GB
to 4 GB allowing them to provide higher resolution textures and better
anti-aliasing using more than 2 GB of physical memory.

While it is technically possible to use "Large Address Aware" with special
boot options on Windows 32-bit OS, it's not always stable and really only
gives you something between 2 GB and 3 GB of memory adressing while 64-bit
OS can get up to 4 GB for such 32-bit applications without any strange
configuration options.

To sum up: Even 32-bit games can take advantage of 64-bit OSes for more
memory addressing than it could on a 32-bit OS. Expect this to become
popular faster than making two versions of the same game for most titles.

Crysis installs both 32bit and 64 bit versions
The documentation says that it can make good use of 64 bit hardware to run
faster and more efficiently.
It is possible that even a 32bit Vista but with 64 bit hardware could have
some improvement.
Checking the Games Explorer link shows that on a full 64 bit Vista system
Crysis does indeed use the 64 bit executable (and DX10)

Guess there is just not enough 64-bit users to justify a true 64-bit
game now....

Thanx that also gave me an answer to one of my questions

If you're wondering how crysis would run on that spec...
It would be fine at the highest settings (and looking gorgeous)
It uses multicores for some things (especially when a lot is happening at
once, which is exactly when you need it most !)
Even in severe fights with lots of enemies and explosions its very smooth.
I have a slightly higher system - 6700 quad (6600) and GTX (GTS)
but run at 1920 x 1200 (24") at Very High settings with no problem.
That is the 64 bit version on DX10 (not sure how the 32bit version would
cope, have no incentive to check)

I do run mine at full spec, it does look gorgeous. :D I didn`t know if
it was defaulting to 64 bit or not.

There are not enough 64-bit users out there to justify making the game ONLY
work on 64-bit native. Given that is not an option, you have three basic
choices:

(1) Make two versions of the game, one 32-bit and one 64-bit native. This is
expensive to develop and test. A few games have done this, including
Hellgate London and Crysis.

(2) Make one version of the game, a 32-bit version, that uses the Large
Address Aware feature to give 64-bit users a bit more content than would fit
on 32-bit. This is much less expensive to develop and test, but still means
only 64-bit users really get the benefits of some of the development cost.
This is what Company of Heroes is doing.

(3) Make one version of the game, a 32-bit version, and make it all fit into
the 2 GB limit of 32-bit OSes that still works for 64-bit users. This is
what most games do, although it's getting harder and harder to really do
this for games attempting to take full advantage of modern systems and video
cards.

Of course, there's also a fourth case of "ignore X64 Windows completely",
which is being done by a few too many publihsers still. The Games for
Windows branding is trying to address this by mandating 64-bit compatibility
at a minimum.

Actually according to the XNE SDK the game is REQUIRED to be able to run in
Vista x64, but running in Vista x86 (32-bit) is OPTIONAL! How cool is that?!
MS making a push to drive 64-bit in gaming.

Of course I'm positive no gaming group in their right minds would ship a
game as 64-bit only, but it's good to know they could if they wanted too. ;)

What is the "XNE SDK"?

I don't know, I speak outta my ass all the time.

Usurped by the [MSFT] tag, again.
/sigh

not having a good day.

It's not the XNE SDK, it's the Games for Windows Standards, I read them a
while back when I was at EA, just forgot the name of them. No need to bash
me for saying something nice and missing one minor point CHUCK.
