Helldivers 2 Dev Worked With Sony Studio Nixxes to Create a ‘Slim’ Version for PC That Reduces File Size From 154GB to 23GB

The studio had warned that changing the file size of Helldivers 2 might have increased load times by a factor of 10 — indeed that’s why it duplicates data with update releases. But it turns out that its worst case projections did not come to pass.

“These loading time projections were based on industry data — comparing the loading times between SSD and HDD users where data duplication was and was not used,” Arrowhead explained. “In the worst cases, a 5x difference was reported between instances that used duplication and those that did not. We were being very conservative and doubled that projection again to account for unknown unknowns.

“Now things are different. We have real measurements specific to our game instead of industry data. We now know that the true number of players actively playing HD2 on a mechanical HDD was around 11% during the last week (seems our estimates were not so bad after all). We now know that, contrary to most games, the majority of the loading time in Helldivers 2 is due to level-generation rather than asset loading. This level generation happens in parallel with loading assets from the disk and so is the main determining factor of the loading time. We now know that this is true even for users with mechanical HDDs.”
