Actually, I do know that RAM / NVRAM are different & both operations are known to Me. I was more asking about the software-rngineering side of how the major OS / kernels use the swapfiles, & if it would theoretically be programmatically fast enough to make a difference for the WinXP / Win7 gaming I do. [Keep in mind that the older systems are using DDR2 at around 670-800Mhz with P4 processors around 2.2ghz].
