What is this cache people speak of? Windows cache? How does it work?
Ever since windows Vista, windows has a caching feature that stores stuff you've accessed recently in to RAM, so when you launch the program again, it loads it from the RAM instead of the HDD/SSD. It sounds like this program is allowing you to load your whole game folder into that cache, so when you launch the game, it's loading everything from the RAM cache, instead of from disk.
The game will still be loading the data from the RAM cache to the spot in RAM it loads it's data in to... but it will be a RAM -> RAM transfer, which will obviously be faster than SSD, and tons faster than HDD. The only way to be better would be if the game itself paged everything it could possibly want in to RAM on startup... but the game itself would have to be coded to do that. None I know of do... haven't seen anything with "minimum system requirements: 20GB RAM"
I've actually been using a RAM disk to load games in to, but this is a much more elegant solution. I'll have to try it out.
