Some Diskspan GUI settings for The Sinking City - The Merciful Madness and Starfield
Feel free to alter the LOLZ_ST lines to whatever you feel comfortable with if you don't like to wait for unpacks.

The Sinking City - The Merciful Madness 47.5 GB -> 27.1 GB

For the OGG files you have to extract them first (with BAE tool), erase them out of all the files (with xtool erase command), compress them with oggre. After installation, you have to put all the OGG files back inside the original bsa files (with xtool decode command + XTL file).

BIK file use bpk.

Edit: You can also use bethesda.bms with quickbms instead of BAE if you want.

 18:53:04 - Overall output size: 5,41 GB (Ratio 45.41%)
 18:53:04 - Overall conversion time: 00:57:28

Install time + decoding BSA files 10 minutes.

Edit 3: Keep in mind that the input size is a bit inaccurate due to extracted files, as the BSA files are still the original size but with zero'd data inside.

One cons is decompression time: about 19 minutes! How can I reduce this time? How did you obtain 10 minutes of decompression time?

MSC's MP3 codec is quite slow. I'd recommend try mpzmt by BlackFire69 with srep after.

Don't use srep+lolz after oggre.

[KaktoR]

There is a 7zip MP3 plugin which is super good, even better then mpz, and it will not be detected as virus unlike mpz (false positive)

[shazzla]

Can it process stream ,or only for file ?

[KaktoR]

Both.

7zdll
Compressed 1 file, 1,135,385,600 => 918,525,479 bytes. Ratio 80.90%
Compression time: cpu 0.73 sec/real 78.90 sec = 1%. Speed 14.39 mB/s
All OK

mpzmt
Compressed 1 file, 1,135,385,600 => 922,505,962 bytes. Ratio 81.25%
Compression time: cpu 0.44 sec/real 75.45 sec = 1%. Speed 15.05 mB/s
All OK

Thanks so much for your help!!! Not only compression ratio is slightly better, but i've also saved at least 5 minutes of decompression time! Now, the bottleneck is .ogg file decompression, it still takes too long. Is there any compression that can allow me faster decompression time?
I'll try to extract only .mp3 and .wav files from .bsa files to understand if it worth it in terms of decompression time!

You cannot speed up oggre.

Good evening! Concerning Fallout New Vegas, if you extract only .mp3 and .wav files, the final size is compressed videogame about 140 MB bigger than the version with .mp3, .ogg and .wav, but compression time is about half time!!!
So it can worth it!

If some kind soul can reveal method used for Monster Hunter Rise .pak files? Can't figure this one out...only two .pak files should be encrypted and with zlib and zstd streams but there is no AES key for this anywhere and using xtool on this will produce only small gain...but I saw few repackers ratio was *much* better. Tried creating database also but without luck.
Thanks in advance, regards.

zstd.

Use xtool 0.8.4 + libzstd 1.1.4

https://www.patreon.com/posts/97128362

Streams: 77311 / 77311
Time: 00:05:06 (CPU 00:01:06)

Size: 34.5 GB >> 48.2 GB

Done!!!

Actually there are even some zlib streams.

Streams: 20756 / 20756
Time: 00:03:52 (CPU 00:14:47)

Size: 34.5 GB >> 36.0 GB

Done!!!

[infovs]

^you're right KaktoR, I was using most recent version of libzstd without any success but using 1.1.4 from 2017 worked like a charm! If I may ask, how can one pinpoint exact version of libzstd to use? I tried everything, yes I even tried different versions of libzstd but it never occurred to me that I should be using 7 years old dll version
Thanks again,
best regards

Never seen a ReEngine game use anything else but libzstd.dll v1.1.4 when zstd is used by that engine.
