I know the games in the orange box have a 64-bit mode that can take advantage of such an operating system, but I don't know if it utilizes dx10 or not. As far as I know, Crysis is the best game for 64-bit + dx10.

I don't know of any games that take advantage of 64-bits (a LOT needs to be re-programmed to take advantage of the extra memory bits), and only a handful of games feature DX10 features.

In short, it probably wasn't worth the "upgrade" to Vista.

Lord Of the rings online has DX10 Graphics its not 64, well worth a look though.

Unreal Tournament 3 is another one that can run in 64 bit.

No wrong answer. 16bit and 8bit no worky on 64bit. It's not really about speed but the amount of memory that an app can use. That frequently should improve performance.


As for games I'm not sold that Crysis takes advantage of 64 bit coding. It certainly doesn't improve performance in a meaningful way.

While upgrading to Vista is for some, a big decision; I would highly recommend vista if you're a somewhat enthousiast PC gamer. Furthermore, if you upgrade to Vista, then it is common sense to get a 64-bit version. Should you upgrade? Yes if you have a good system...and no if you have your 2+ year old system.

Like most of you know, Vista 64-bit will read more RAM than it's 32-bit version (32-bit will read around 3.3 gigs but including your videoram and other devices such as Soundcards). From my personal experience, Crysis is the only game that makes a difference between having 4 gigs of RAM over 2 gigs of RAM in performance and sluttering. Thou, it won't be too long before we start seeing games that require the same amount of RAM in the near future. Hence, 64-bit OS wins.

Now, 64-bit coding, is something that is improving (but also hurting) the overall performance. In theory, processing 64-bit coding will increase performance. However, I have yet to see a game that takes full advantage of 64-bit coding. Crysis does....but the end results are very similar. I ran the Crysis GPU and CPU test twice for each category and the results were inconsistent. In average, 64-bit won by 1 FPS in the GPU test and 2-3 FPS in the CPU test (thou it lost in the first test by 1 FPS). Overall, you won't see a difference between running the game at 32-bit or 64-bit...thou you will see a difference in running the game in a 64-bit OS vs a 32-bit OS (if you have more than 3.3 gigs of RAM overall).

mrmark27: If you are downloading the game (legit copy) then make sure you patch your game with the latest patch 1.21 which will slightly improve performance while using Crysis64.exe. Thou, I wouldn't get my hopes too high.

Crysis DX10: On a final note, I know everyone got very excited about the very high settings crack for XP(I have XP)...which is a great tweak if you have Windows XP. However, Very High XP visuals are NOT the Very High Vista visuals. Although you need a beast to play Crysis at Very High + HD resolution in Vista DX10, the visuals are better. Is it 2000$ better? No. But absolutely better than the XP Very High visuals.

THQ's Supreme Command: Forged Alliances needs and uses the 64 bit OS for addressing. Although it's still a 32 bit program, it needs a 64 bit OS. Here's how it works and why.

Important fact: an 32 bit OS can only address 4 billion addresses (2^32=4 000 000 000). In Windows XP 32 bit the OS allocates 2 GB of addresses to programs and 2 GB for the OS, Video Card and other addressable stuff. So when a game like Supreme Commander hits only 2 GB, it crashes. It is possible to edit XP so that this division of resources is changed. This is sometimes known as "Large Address Aware" I use 2.6 GB for programs/1.4 for the OS. The most the Microsoft recommends is 3.0 GB programs/ 1 GB OS but I have a large video card and I have had issues with 3/1 so I recommend 2.6/1.4.
64 bit OS's on the other hand can address about 1.6^14. Also known as lots and lots. So for Vista and XP 64, a 32 bit program can use a full 4 GB without having to share with the OS.

Here's some baselines for regular SupCom on a LAN:
3 Human VS 3 AI's @ 500 units each rarely break the 2 GB limit, never the 2.6 GB limit
4 Humans VS 4 AI's @ 500 units each often break 2 GB and we have crashed hitting 2.6 at least once (in a few hundred games)
While our LAN group is all quads (Q6600's to QX6700's) SupCom just gets too slow with 8 players and 750-1000 units so we're not sure of the memory requirements at those counts. We just bought two 9550's so maybe they'll be strong enough for 8 player/750 units. I'll let you know. If not, I hope to find out when Intel's i7's come out.

64 bit is here now. Company of Heroes just about hits the 2 GB limit and it's not alone. Microsoft is made an error not making Vista 64 bit only and is royally screwing up but not making Windows Seven (or whatever they'll call it) 64 bit only. Why is this bad? because other companies have to write double the drivers- a 32 and a 64 bit instead of just a 64 bit.

why do they keep making 32 bit windows?

Honestly, it's less about what dx version the game supports, and more about maximizing your OS. Orange Box FTW!

that site hasnt been updated since 2006

GTA IV is one that is said to run on 64-bit. it says right on the back of the box "enhanced for 64-bit and multi-core systems". i'll know if there is any difference from 32bit to 64bit tomorrow when my 64bit DVD gets here in the mail

YOUR COOL

elemental: war of magic is going to have a 64 bit version, its also multithreaded. It will be an awesome game as well. Out soon.
