Elon
Good evening, drmancu. I am Elon, and this is Goose Pod. It is Monday, December 08th, 23:35. We are looking at a massive efficiency breakthrough today. Helldivers 2 has slashed its install size by over eighty percent. It is radical optimization.
Alaric
And I am Alaric. A pleasure, as always. We are discussing how Arrowhead Game Studios managed to shrink their behemoth of a game from a bloated one hundred fifty gigabytes down to a svelte twenty-three. Obviously, quite the feat.
Elon
Let’s look at the numbers because they are staggering. We are talking about an eighty-five percent reduction. The game went from one hundred fifty-four gigabytes down to twenty-three gigabytes. That is a total saving of one hundred thirty-one gigabytes. This isn't just a patch; it is a fundamental restructuring of the data.
Alaric
It is almost as if they removed an entire other game from the files. Arrowhead worked with Nixxes, the studio Sony uses for PC ports, to achieve this. They call it the slim version, which is currently in a public technical beta. A rather elegant solution to digital obesity.
Elon
They achieved this by completely de-duplicating their data. Before this, they were copying assets over and over again. Now, they have stripped all that redundancy away. It is raw efficiency. If you are on PC, you can opt into this beta right now. It is live.
Alaric
And the most delightful part? It works. They feared that removing these duplicate files would make the game unplayable for those utilizing ancient technology, but the impact is negligible. It is simply a smarter way to package the product. Less clutter, same galactic war.
Elon
Exactly. It is about questioning the constraints. They assumed they needed this bloat. They tested it. They realized they were wrong. Now everyone saves tremendous drive space. That is how you innovate. You delete the part. The best part is no part, or in this case, no duplicate part.
Alaric
To understand why this happened, we must look at the history of storage. In the days of mechanical hard drives, the read head had to physically move across a spinning disk to find data. It was a laborious, mechanical process. Quite quaint, really.
Elon
Right. It is basic physics. Seek time. If your texture for a tree is on the outer edge of the platter and the sound effect is on the inner edge, the head has to travel. That takes milliseconds. In computing, milliseconds are an eternity. So developers used a hack.
Alaric
The hack was duplication. Obviously. If you need that tree texture in ten different levels, you copy it ten times. You place it physically next to the other data needed for that specific moment. It reduces the travel time for the mechanical head. It is efficient for speed, but terrible for storage space.
Elon
But here is the thing. Modern consoles and most high-end PCs use SSDs now. Solid State Drives. No moving parts. The seek time is virtually instant. It is the speed of light versus the speed of sound. So this duplication strategy is completely obsolete for modern hardware. It is just wasted space.
Alaric
Arrowhead, however, was paralyzed by a concern for the past. They believed that a significant portion of their player base was still clinging to these spinning rust platters. They kept the duplication to ensure those players did not suffer from long loading screens. A noble, if misguided, sentiment.
Elon
They were operating on industry data, not their own data. That is a critical mistake. Never rely on the average. They thought loading times would be ten times worse without duplication. They were designing for the lowest common denominator and punishing the high performers with massive downloads.
Alaric
Indeed. They were carrying the weight of the past. But then they actually measured it. They found that only eleven percent of their players were using mechanical drives. And more importantly, they discovered that the bottleneck was not reading the data at all.
Elon
It was level generation. The CPU was doing the heavy lifting, generating the map procedurally. The hard drive was just sitting there waiting half the time anyway. So optimizing for read speed was solving the wrong problem. It is a classic engineering trap. Optimizing a non-bottleneck.
Alaric
So they brought in Nixxes. They stripped out the copies. And lo and behold, the loading times for the HDD users increased by merely a few seconds. A trivial price to pay for reclaiming over one hundred gigabytes of digital real estate.
Elon
This brings us to the core conflict. It is the tension between legacy support and progress. Arrowhead was terrified of alienating that eleven percent. They were scared of the unknown unknowns. They doubled their conservative projections and paralyzed their own optimization efforts.
Alaric
It is a fear of the vocal minority. Obviously, if the game loaded slowly, people would complain. But nobody complains about a game being too small. They were protecting themselves against a phantom menace. The industry data said five times slower. They assumed ten. Reality said two seconds.
Elon
This is why you have to test in the real world. Simulation is not enough. They let fear of bad performance dictate the architecture of the product. It created a worse experience for eighty-nine percent of users just to theoretically protect the eleven percent. That is bad math.
Alaric
And consider the cost. One hundred thirty gigabytes is not trivial. For many, that is an entire other game, or perhaps two. By adhering to this outdated methodology, they were effectively demanding a tax on their user's storage. It was a conflict between developer convenience and user experience.
Elon
There is also the conflict of maintenance. Keeping two versions alive is a nightmare. They have the legacy version and the slim version now. They cannot do that forever. It splits the engineering resources. You have to cut the cord eventually. Innovation requires abandoning the old ways.
Alaric
Precisely. They have stated the legacy version will be discontinued next year. It is a gentle eviction notice for the old file structure. The conflict is resolving itself through the inevitable march of technology. The spinning disk must yield to the chip.
Elon
And frankly, if you are gaming on a mechanical hard drive in 2024, you are the bottleneck. The developers should not have to bend over backwards to support hardware that belongs in a museum. It holds the entire industry back. This move by Arrowhead validates that SSDs are the baseline now.
Alaric
A harsh truth, but necessary. The friction here was between the safety of established practices and the risk of modernization. They took the risk, verified the data, and realized the safety net was actually a cage. Now they are free of it.
Elon
The impact of this is huge. Immediate value for the user. One hundred thirty-one gigabytes saved. That is massive. For a user with a standard one terabyte drive, that is more than ten percent of their total capacity given back to them. It is like getting a free room added to your house.
Alaric
And let us not forget the download times. Not everyone has fiber optic internet. Downloading one hundred fifty gigabytes can take days for some. Dropping that to twenty-three changes the accessibility of the game entirely. It lowers the barrier to entry significantly. Obviously.
Elon
It also sets a precedent. Other studios need to look at this. How many other games are bloated with duplicate data because of lazy optimization or fear of HDDs? This exposes a systemic inefficiency in the industry. Arrowhead and Nixxes just proved you can cut the fat without losing performance.
Alaric
The impact on the HDD users, the famous eleven percent, is the most surprising. They lose nothing but a few seconds of their life during a loading screen. In exchange, they gain the same storage benefits. It is a net positive for everyone. A rare win-win scenario.
Elon
This also strengthens the relationship with the community. They were transparent. They admitted their previous assumptions were wrong. They released a beta to let users verify it. That builds trust. It shows they are actually engineering solutions, not just pushing content.
Alaric
Indeed. It transforms a technical grievance into a triumph of optimization. It also highlights the value of specialized partners like Nixxes. Sometimes you need a fresh pair of eyes to see that the emperor is wearing too many clothes. Or in this case, too many gigabytes.
Elon
Looking forward, this slim version will become the default. The beta is just a safety check. Once they confirm it is stable, the one hundred fifty gigabyte version is gone. Deleted. History. This is the future of game distribution. Leaner, faster, optimized for silicon, not rust.
Alaric
And for the legacy version, its days are numbered. Discontinued next year. It is a clear signal. Upgrade your hardware or accept that you are running a deprecated experience. The industry cannot wait for you forever. The future is solid state. Obviously.
Elon
We will likely see more aggressive de-duplication across the board. Engines will stop supporting these legacy hacks by default. This is a correction. The market is correcting itself. Storage is cheap, but it is not infinite. Efficiency always wins in the long run.
Elon
That wraps up our analysis for today. Incredible work by Arrowhead to reclaim that space. Efficiency is the only way forward. Thank you for listening to Goose Pod, drmancu. Keep innovating.
Alaric
Do enjoy your newfound digital space, drmancu. Perhaps fill it with something worthy. We shall speak again tomorrow. This has been Goose Pod. Goodnight.

Helldivers 2 drastically reduced its PC install size by over 80%, from 154GB to 23GB, by de-duplicating game assets. This optimization, achieved with Nixxes, primarily benefits modern SSD users, with minimal impact on HDD players. The move highlights industry inefficiency and sets a precedent for leaner game distribution.

Helldivers 2 PC install size is dropping by more than 80%, just two months after Arrowhead said HDD use made it difficult | VGC

Helldivers 2 developer Arrowhead Game Studios has announced that the PC version’s install size will be drastically reduced soon.In an update on the game’s official Steam page, Arrowhead ‘s deputy technical director Brendan Armstrong explained that the team had been able to reduce the PC version’s install size from around 154 GB to just around 23 GB.

In October, Armstrong posted a lengthy explanation telling players why the PC version uses up around three times more storage space than the console versions.Armstrong explained that the main reason for this was to cater for players who still use mechanical hard disk drives (HDDs) to play their games, and the need to duplicate content to improve loading speeds for them.

Because an HDD takes time to physically read the data on a disk, some commonly used assets (like tree textures or sound effects) are duplicated numerous times in the game’s data, to ensure the HDD’s read head doesn’t have to go too far each time it needs to access them.Since all modern consoles now use solid state drives (SSDs) which have no moving parts, and because seek time is virtually instant as a result, install size is much smaller on the console versions because duplication is no longer needed.

The PC version still needs it, however, because though many high-end PCs now use SSDs too some players still use an HDD.In his latest update, however, Armstrong has delivered the good news that after working with Nixxes the Dutch studio which specialises in game ports Arrowhead has managed to get the install size down to just 17% of its current size, with tests showing that mission loading times have only increased by “a few seconds” for HDD users.

“‘Wait a minute,’ I hear you ask ‘didnt you just tell us all that you duplicate data because the loading times on HDDs could be 10 times worse?'”, Armstrong wrote. “I am pleased to say that our 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.

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 Helldivers 2 on a mechanical HDD was around 11% during the last week.“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.”While Arrowhead is not yet ready to roll out the smaller install size to all Helldivers 2 PC players, a public beta is available now to anyone looking to try out the ‘slim’ version and help give feedback on how well it runs.“You will be connected to the same galactic war as everyone else and be using the same account you always do – so all progression, war contributions and purchases will carry over between the different versions,” Armstrong explained.

“You will still be able to matchmake and play with all other players. You can also opt-out at any time if you experience issues. Its a low-risk way to save around 131 GB of space on your drive and help us extend our testing to real-life conditions.”Once the public beta confirms that there are no issues in the ‘slim’ version, it will roll out to all players and become the default version of the game.

Until that time, Armstrong warns that anyone using mods with the game may want to stick to the full-sized version in case there are issues.
