Respawn explains why Titanfall PC requires 48GB of disk space

Xbox One version only takes up 17GB

Respawn has given the main reason why the PC version of Titanfall requires 48GB of hard disk space whereas the Xbox One version only needs 17GB.

The studio's lead engineer Richard Baker told Eurogamer that the PC installation includes 35GB of uncompressed audio, whereas the Xbox One version's audio is compressed.

Baker explained that since Titanfall dedicates a sizeable proportion of CPU time to decoding the game's audio, by ensuring the PC doesn't have to also decompress that audio the CPU spends less time working on it. As a result, the game can run better on less capable PCs.

The Xbox One, meanwhile, has a built-in audio decoder meaning it can handle compressed audio, hence the smaller install.

"Basically, when you download the game or [install from] the disc itself, it's a lot smaller than that," Baker said. "We have audio we either download or install from the disc, then we uncompress it.

"We probably could have had audio decompress off disc but we were a little worried about minimum specifications and the fact that a two-core machine would dedicate a huge chunk of one core to just decompressing audio.

"So it's almost all audio. On a higher PC it wouldn't be an issue. On a medium or moderate PC, it wouldn't be an issue, it's that on a two-core [machine] with where our min spec is, we couldn't dedicate those resources to audio."

Respawn's debut game is now available on PC and Xbox One in North America ahead of its rollout in other regions throughout the rest of the week. The Xbox 360 Titanfall release date is March 25 in the US and March 28 in Europe.
