If you are a PC Titanfall player, you may have noticed that you had to download an amount of data that would make anyone with a capped data usage wince in the past couple days. Somewhere in the region of 48GB to be precise. This might seem a touch unreasonable for any number of reasons but the number one reason is probably the requirement to have all language audio files downloaded. That's uncompressed at that.
While its almost understandable why the audio is uncompressed (to allow lower performance machines to spend less time decompressing it), it does seem a fairly large ask to download files that the majority of people just aren't going to use. I don't speak French, so why would you ask me to download gigabytes of pointless audio in that language?
This is also a large shout from the 17GB install required on the Xbox One which, while still fairly hefty, is a lot more palatable. Again, this is due to the level of compression used on the audio files, with the console version being able to do this quite comfortably.
So, for those people outside of the US who have given little thought to pre-loading the game. Pre-load your game. Unless you have a monstrous download speed, you will be spending quite some time watching a progress bar on release day if you leave yourself unprepared.
