Certain games are incompatible with 64-bit versions of the Windows operating system – but why? And what steps can be taken as a workaround?
What is Windows 7 64-Bit?
Windows 7 64-bit is a version of Microsoft’s current operating system designed for use on 64-bit systems. A 64-bit system can be identified in Windows by going to Start, right-clicking Computer and choosing Properties. This will display the System screen, where the OS type will be listed against System Type.
A 64-bit system is more advanced than a 32-bit one, and requires just a 64-bit CPU and compatible motherboard to be designated as such.
Certain games and applications will not run well under Windows 7 64 bit – this is a fact. The problem here is with the way RAM is handled; a different volume of data is processed in a 32 bit system than in a 64 bit system.
What 64 bit Windows offers is a step into the future without upgrading all hardware at once, and without requiring all applications to be rewritten. This is thanks to an architecture devised by AMD which specified how to process information from 32 bit into 64 bit.
Windows 7 64 bit will largely allow 32 bit software to run without problem, although as we will see, there are some problems with game compatibility
Why Some Games Aren’t Compatible
Compatibility for games depends on development. Basically, Windows 7 64-bit wasn’t expected to be much of a hit when most games available in 2010 entered development back in 2007/2008. As a result, many games available in 2010 were designed to be 32-bit.
As it is, according to Steam, 31% of gamers using that service are running Windows 7 64-bit in 2010.
Additionally, with games developed to be compatible with 32-bit versions of Windows there is no reason to expect any problems with 64-bit compatibility if, as we’ve seen, 64-bit processor architecture is designed to accept 32-bit data as well as 64-bit.
