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
Several of those games are not 64-bit games, and neither is The Witcher. They just had patches released so they would run better (or at all) on a 64-bit OS while still being 32-bit software.
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.
A 32-bit EXE and a 64-bit EXE will not use the same amount of RAM, the 64-bit EXE will use more because the pointers and so on are larger.
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!!!
Do you seriously belive that fake rumor? :blink:
We won't see any 128-bit OS anytime soon, if ever.
Ever. And x86 won't die anytime soon either, there is simply too much software available using it. If Microsoft dropped their 32-bit support in future 64-bit Windowses, they would recive hell not only from users but from companies as well.
It will still run, but it will only be able to use a up to like 2 gb of RAM. Once you start modding, that can be nothing. Plus, if you look at the other thread on the topic, there's a possibility that within four years or so, 32 bit architecture will be dead.
If the 32-bit EXE have the "IMAGE_FILE_LARGE_ADDRESS_AWARE" switch enabled, it can use up to 4GB RAM in a 64-bit Windows.
And no, there is no possibility that x86 is dead within 4 years, at all. Well, I guess it would be dead if Earth exploded, but then that would be the least of our problem.
