That reminds me, like 2 weeks ago I started to get shader errors, the purple question marks, you know the ones. So I uninstalled the game, cleared my shader, and then reinstalled.
I was confused because I knew the filesize was 130gb but redownloading the game was only like 30gb. So I guess you download all the assets, and then when they deploy they just duplicate themselves.
This means that there is no practical benefit to optimizing the final file size because the main incentive for companies to do that is to decrease the overhead on hosting the download files. Since in this case the download size is optimized, they'll never do anything.
