All it is in place of it getting the texture data from the disk all the time and it putting alot of stress on your drive it is cashed to the hard drive, so your blueray drive wont go crazy like is dose in blackops 1.There are no real ingame advantage/texture gain its just less stress on the drive.
Awesome to see this.
Big plus for the game and the PS3. My Blu-ray drive died when playing BOps, a little part of me died too and had to sell a little part of my soul to get it fixed.
I'm seriously overjoyed at this
Props to Robstang as well for always fighting for some sort of installation on the PS3. Props to Vahn for doing it.
