See if not compressing the pak will decrease download time

The documentation says “Steam compresses files while they are being downloaded by users, so initial download times will not be affected by your game’s .pak file being compressed. However, Steam’s differential patch system will work better with uncompressed files. Compressed .pak files save space on the customer’s system, but will take longer to download when patching.”

Is it possible to test if having the pak file uncompressed can reduce the download size of updates? If it does, we could have the loading benefit of pak without the current download update size disadvantage, and wouldn’t need to update UE4 to split the pak into multiple paks.

This is something that could be tested when there is time to do so, however some of the speed increases come from the PAK file being compressed, as there is physically less data that has to be loaded from the disk.

IIRC PAYDAY 2 uses the best of both worlds: On update, the game was decompressed on disc, updated, then the updated data compressed.
