Eh? I don't quite understand, but I believe what you're asking for is impossible. Are you talking about something that pre-caches the Game resources(I.E. Textures, objects, etc..) into the RAM for faster loading times? If so, probably not. You would have to have quite a large portion RAM for it to work, even if it were possible.
Yup thats what im talking about. A buddy of mine says he found it awile back and cant remember.
He might be thinking of a similar program or mod; Perhaps one that clears the cache?
Well, there are a few of 'em out there, but a fairly popular one is called Streamline, which clears the Cache on a regular basis.
