"In an ideal world, that would be all we have to say about the new solution. But for Windows users, there's a special quirk. On most operating systems, we can use a special flag to signal that we don't really care if the system has 32 GiB of real memory. Unfortunately, Windows has no convenient way to do this. Dolphin still works fine on Windows computers that have less than 32 GiB of RAM, but if Windows is set to automatically manage the size of the page file, which is the case by default, starting any game in Dolphin will cause the page file to balloon in size. Dolphin isn't actually writing to all this newly allocated space in the page file, so there are no concerns about performance or disk lifetime. Also, Windows won't try to grow the page file beyond the amount of available disk space, and the page file shrinks back to its previous size when you close Dolphin, so for the most part there are no real consequences...

seems its not without perils on Windows:
