    Do games auto-detect 64-bit?

    I have a question, do games such as Oblivion, Fallout 3, COD4, The Witcher, etc. auto-detect you have a 64-bit os or due your have to somehow set it to 64-bit everytime you run the application?

    It should run in 64 bit to fully optimize the game. That seems b.s. to me.

    A program will run in 64-bit mode only if it has been specifically compiled for the 64-bit arch. In 64-bit Windows, 32-bit programs run under a compatibility layer called WOW64, or "Windows on Windows 64" (sounds kind of dirty...). Anyway, nobody is trying to scam you on this one.

    what bog said, if it was made for a 64 bit environment, or if there is a separate thread capable of 64bit, then it will run as that, but other wise( and usually for games) it will be 32 bit.

    some games have a 64bit executable.

    most do not.

    i dont think any of the games you mentioned are compiled for 64 bit.

    some games that have 64 bit versions include:

    (older games):

    Half Life 2
    Far Cry
    World of Warcraft

    (new games):
    Crysis, (soon, if not already) Crysis Warhead
    others i dont know about

    Some games are also optimized to perform better in the x64 enviro, such as GTA IV, even though the actual applications are compiled in 32-bit.
