AAA games seem to have totally given up on compression and even just common sense when it comes to file sizes lately. Was it Titanfall that came with gargantuan uncompressed audio files, for every possible language you can play the game in? It's ridiculous. Even if you accept that there's a noticeable performance increase when using uncompressed files[footnote]Which is something I don't actually accept at all, especially in the case of audio files.[/footnote], there's no reason at all you couldn't just download a compressed version of the files and then unpack them during the install. The minor increase in install time would be more than made up for by the huge decrease in download times even on systems with fast connections.
So basically, I don't get it. There must be some reason PC games suddenly got so huge, I doubt it could just be some kind of mistake, but the explanations I've seen don't make sense.
The basic reason amounts to storage is cheap, processing is expensive. Decompression of resources, audio especially, in real time requires a lot of processor power which is just not practical in a high performance application. Therefore this processing time is pushed to the loading. This is why back on the Xbox 360 we had such atrocious load times (Mass effect elevators anyone?) The console did not have guaranteed storage and a very small amount of space on the DVD, so The game data was compressed on the DVD and then decompressed when it was anticipated it would be needed.
This is one of the reasons League of Legends has a 5 gb foot print but every game starts with 90 seconds or more of loading.
So, general rule: storage is cheap, processing expensive. So you can have a processor heavy solution (compressed files) or a storage heavy solution (uncompressed files.) Which do you choose? The answer is obvious: The cheap solution, the storage solution.
Also, most games do come down compressed and are decompressed on install. I don't know of any large footprint games that don't do this. For example, titan fall had a 50 gb install, but you only downloaded like 15 gb.
