The sad fact is, making a 64-bit EXE of anything but a very simple program run correctly is hard. Not because it's hard to compile such a program (it's just a bunch of flags in the compiler/IDE), or hard to keep your code free of 32-bitness assumptions (that's just a matter of the correct style guide, which you should have anyway, like "don't use int if you need a 32-bit integer value; use int32_t"). The problem is that almost any bigger program requires the use of external libraries, and those aren't all 64-bit ready yet, or may have bugs in their 64-bit versions, and (on Windows, at least) you almost never have the source code to those libraries available to fix their problems yourself.

Open source programs using open source libraries have it way easier - my Linux server has been running 100% 64-bit since three years.

Indeed, I think this is a non-issue.

Umm...
Perhaps they don't add a 64bit exe because the game doesn't need it ?
It's too early for games to jump at 64bit computing,it would be an overkill.
The only game that ever had 64bit was the first Crysis,but that was mostly for the hungry Sandbox editor to work,not the actual game.
Perhaps TES VI or VII will have 64 bit.

Won't a 32 bit run just as good on a Windows 7 computer? as in, It won't detract from the game?

I'm not an IT genius :hehe:

I am preeeeeeeetty sure that it has been done before. Can't remember what game it was for the life of me, though. =/

Plus dx11 optimizations. I cant imagine playing a TES game without a CS/CK...

PC isnt completely forgotten, and to be fair hardly any game comes with a 64 bit exe, RE5 is the only one i can think of.

Wha? How does steam prevent 64bit exes? Beth is the one who makes it. I'm pretty sure steam would allow them to have a 64bit exe :confused:

My guess as to why BGS is doing this is the benchmark they may be using for cards and number of available drivers. Limiting liability so to speak. Anyways, what ever the reason it doesn't really bother me. I'm sure the game will look and perform just fine.



I second this question.



On Win7 Witcher was released "enhanced 64bit multi-core". http://www.start64.com/index.php?option=com_content&task=view&id=190&Itemid=116. Not sure why since the architecture has been around since the 1960's

Creepy I was on that site a few seconds ago looking for a list of 64 bit games :spotted owl:
I wouldn't call a list of 13 games (plus a few unlisted apparently since the witcher wasn't there) impressive by any means so my point stands. Very few games have 64bit support so expecting it is a bit unrealistic and considering people have shown that it is not really necessary, even more so.

Console port.

But im sure there will be a mod that fixes that.

Im using Windows 7 64 bit, will Skyrim not work then on mu PC

yes .it will work fine!!

It should work fine.

But the point that Witcher could do it, and that game company was FAR smaller (I asume we are talking Witcher 1? but even in 2 that is case) why can't beth do it?
Not to mention your point is, considering there are not many open world RPG games, it was unrealistic to expect that the game will ben an open world rpg?
I hate those 'It is not done all that often, so it should not be done, even if it is easy to do and logical' stuff

Isn't the games memory usage in the actual code, not the compilation method? Meaning that a 32-bit EXE and a 64-bit EXE will use precisely the same amount of memory unless the developer decides to re-code a part of the game. Yes, 64-bit theoretically allows an application to use more than 4GB of RAM but unless the application has poor memory management or is designed to specifically use more than 4GB, it never will use that much.

For those saying the game won't need more than 2GB of ram, it will its called mods.

wow... my oblivion is 19GB XD
EDIT: or is RAM something else then memory space... (i dont know what RAM is)

You dont need a x64 exe for a game for it to look good, and its my understanding that no games ive ever seen have a x64 exe, thats all application stuff.

I never said they couldn't for one. And my point is not many games do 64 bit exe so it's unrealistic to expect it considering how few games do it (I bolded it to make it easy to understand for you because you don't get it obviously ). Not whether or not it's an open world rpg which is a (extremely ridiculous) strawman TES games are all open world rpgs. How does that even pertain to my point?
I never said it was an excuse, or that they shouldn't do it because it isn't the norm, I said it was unrealistic to expect it and then be let down when 64bit games are not the norm. Oh and if it's so damn easy as you say why is every game not 64 bit hmm?
I hate those I have to quickly post a snide and stupendously ignorant comment type of people. :facedesk:

And nice math you did there.


W7x64 - 42.41%
Vistax64 - 13.20%
XP x64 - 1.15%
---------------------
Total x64 - 56.76%

A majority of users use an x64 OS.



TES games have a long life cycle and just as including DX11 is important to contributing the benefits of that life cycle and x64 holds the same potential contributions for super resolutions, ultra textures, new scripting, etc.

To that end an x64 .exe should be included. There is no reason x64 support can't be included.


Edit: If you want a better reason to include a 64bit .exe, just know that the life of x86 [32bit] is likely shorter than the life of Skyrim.



32bit WILL NOT survive the decade.

Skyrim NEEDS a 64bit .exe!!!

I have a feeling that Skyrim will get Updates for a Year and then Bethesda will drop the Game like Yesterdays News and we wait 4 Years for TES6 while Skyrim wont work well on my PC nomore.

Bethesda does tend to stop patching when the GOTY is released,

Here is a thread in OB moding that go's to show that we need http://www.gamesas.com/index.php?/topic/1176244-oblivion-and-memory-usage/ Its my modded OB much more stable.

I was replying to the other guy's assertion that "most modern gaming machines run 64-bit Windows 7." Nice reading comprehension you did there.

Well can devs then make patch thats add support of 64Bit systems?
