4.3 gig is the system cache, not the cache for GTA.
That's the same general cache as games like Oblivion use, I think. Although Oblivion said on the back of the box regarding caching (or in the game manual?). If it uses cache I think it will say somewhere, the fact we have not heard means it probably doesn't. (I can't think all the "professional" review sites and "geeky" internet users have missed this!)
No, I believe you could count on one hand the games that use the cache (maybe 2 hands). I think they "have" to state on the box so we would know if loads of games were doing this.rp2000 - I think cache is used on quite a few 360 games
it just happens in the back-ground .. so you are not aware of it- and it doesn't show up in any of the 360 menus to show what is being cached and what not !!
