UE4 archive compression ratio - BL3, SOD 2

[Anonymous0000]

I have a question regarding UE4 based games like Borderlands 3 and State of Decay 2, where I can't get my compression ratio anywhere near fitgirl's version. I've scoured the forum and didn't find any relevant info. BL3 in particular, has at least 80ish GB/105GB compression with different combination of algorithms, zlib/lz4/preflate, etc. I've heard different UE4 games have different encryption keys, but selecting it in DSG doesn't seem to make any difference.

Can anyone share how they compress these UE4 games?

Cannot comment on Borderlands 3 because never touched it but State of Decay 2 uses some wacko LZ4 concoction.
