Full install of 360 ( which doesnt install the high res textures ) is only 3.8 Gigs.. playing by full install plays low quality textures. Playing from disc will give you the high quality textures...There is more data on the Skyrim 360 DVD then a full install ( because of the high quality textures ) its unknown whether high qulaity don't load ( on ful install ) because of a bug or because the game is optimized to run better from the DVD player, which may run smoother from DVD with high quality textures then trying to run from the HD when the memory system is already heavily loaded.
The PS3 version installs a mandatory 5.3 Gigs because the Bluray player is much too slow in loading high quality textures from disc...The game itself is likely alittle under 6 gigs.. To those observing would argue the Bluray Disc holds much more data - appearing to make the game look bigger - but this is because its holds data for all world regions ( much space is taken by lossless uncompressed audio for all languages - unlike DVD which ships different languages per region, which is not on the Xbox version )
The PC version full install is 6 Gigs ! ?Yes, thats right.. only 6 gigs..
There you have it folks.... Anyone wondering why most of the best games available use less then a DVD's worth of data no longer have to wonder why.. its because for the most part we really dont need it..
