I've just bought a new game, Medieval II, and it requires 512 MB if RAM. My computer only has 256 MB. However, i've heard that you can make up that difference in using virtual memory instead. I found in my system setup how to increase how much virtual memory is used as paging files, but I've also got an 500 GB external hard drive. I know that your supposed to use your primary hard disk for virtual memory, but would it be ok to use alot of the space on the external hard drive to run the game better?
