alt Hacker NewsThe problem they fixed is that they removed a common optimization to get 5x faster loading speeds on HDDs.
That's why they did the performance analysis and referred to their telemetry before pushing the fix. The impact is minimal because their game is already spending an equivalent time doing other loading work, and the 5x I/O slowdown only affects 11% of players (perhaps less now that the game fits on a cheap consumer SSD).
If someone "takes pride in their work" and makes my game load five times longer, I'd rather they go find something else to take pride in.

And others who wish one single game didn't waste 130GB of their disk space, it's fine to ignore their opinions?
They used up a ton more disk space to apply an ill-advised optimization that didn't have much effect. I don't really understand why you'd consider that a positive thing.
23 GiB can be cached entirely in RAM on higher end gaming rigs these days. 154 GiB probably does not fit into many player's RAM when you still want something left for the OS and game. Reducing how much needs to be loaded from slow storage is itself an I/O speedup and HDDs are not that bad at seeking that you need to go to extreme lengths to avoid it entirely. The only place where such duplication to ensure linear reads may be warranted is optical media.
According to the post, "the change in the file size will result in minimal changes to load times - seconds at most."
It didn't help their game load noticeably faster. They just hadn't checked if the optimization actually helped.
If this is a common issue in industry why don't game devs make a user visible slider to control dedup?
I have friends who play one or two games and want them to load fast. Others have dozens and want storage space.

Not what happened. They removed an optimization that in *some other games* ,that are not their game, gave 5x speed boost.
And they are changing it now coz it turned out all of that was bogus, the speed boost wasn't as high for loading of data itself, and good part of the loading of the level wasn't even waiting for disk, but terrain generation.
