I just bought a copy in ps3 and didn't have time to play it before class so I was just browsing through menus. When I loaded up multiplayer and went to the options there was an install option for textures. As far as I can tell the game does not tell you this is even there and I'm not sure if you need to do it for the campaign or zombies. I just found this kind of crazy and wanted to let you all know if you were unaware before.

It doesn't make the game look better it just puts less stress on your PS3's Blu-Ray drive.

It's only for the PS3 and it is "intended to reduce strain on the PS3's Blu-ray drive during extended gameplay sessions." Link.

Yeah I am the kind of person who goes through all of the options menus before I start a game and I noticed this too. The install was a bit over 1800MB on PS3.

What a weird place we're in with this generation of consoles!

Because it is a pack of textures?

It's sort of great that it is there. My PS3 was really loud and exhausted from playing MW3 to the point that I was worried.

I thought for a second that the PC version had high res textures or something.

Could this be related the PS3 lock up issue mentioned in another thread?
