I don&#x27;t think I&#x27;ve touched a game on PC where you can&#x27;t fit all the levels into RAM, let alone just the current level.  Sometimes you can&#x27;t fit music and videos into ram, but you can stream that off the slowest clunker in the world.  A game that preloads assets will do just fine on a bad drive with a moderate amount of RAM.  Loading time might be higher, but the ingame experience shouldn&#x27;t be affected.<p>As far as swapping, you do want a fast swap device, but it has nothing to do with &quot;Since CPUs aren&#x27;t getting faster&quot;.  You&#x27;re right that it&#x27;s IO-bound.  It&#x27;s so IO-bound that you could underclock your CPU to 1&#x2F;4 speed and not even notice.<p>So in short: Games in theory could use a faster drive to better saturate the CPU, but they&#x27;re not bigger than RAM so they don&#x27;t.  Swapping is so utterly IO-bound that no matter what you do you cannot help it saturate the CPU.<p>The statement &quot;Since CPUs aren&#x27;t getting faster, making storage faster is a big help.&quot; is not true.  A is not a contributing factor to B.
