Hello, good noon.

Just want to ask about "System Requirements" of the software. My question is, why they always increases the system requirements everytime they release a NEW version?

Take care and God bless. I have been wondering the same thing one thing that "New versions" are designed to take advantage of are faster computers or processing. For example, when the Original Pentium was released it introduced the MMX instruction set. From that point on, program vendors could either:

make their code use MMX
make their code use MMX, but also implement the MMX portions using 486 compatible calls
ignore MMX entirely.

Most vendors went with the second option. But now that MMX is ubiquitous it's almost forgotten. Nobody makes special branches to handle older hardware (by older I mean without SIMD or MMX), so it simply won't work on them anymore.

With a OS like, say, Vista- it's wasn't EVEN designed to run on computers that existed at the time, but rather for computers that would exist. And it runs fine on a computer today. People have this misconception that if they use an older OS on their newer computer- like XP- they'll suddenly have more "free processor" or something to play games. This is false, the only thing using an old OS on a new computer does is limit your options, your available Memory, and it doesn't make use of your shiny new graphics card UNLESS you happen to go into a 3D MODE.
