Best Compression Methods for 'Specific' Games. Q&A

[KaktoR]

The Witcher 3 Wild Hunt Remastered

Looks like they switched completely to zlib only.
No more doboz+lz4hc.

But I have to wait until it's completely downloaded.

Edit:

Processing input: I:\SteamLibrary\steamapps\common\The Witcher 3

Streams: 568560
  - zlib = 412593 (59,35%)
  - brunsli = 1172 (0,46%)
  - zstd = 26 (0,00%)
  - mermaid = 3 (0,00%)
  - png = 409 (0,05%)
  - leviathan = 3 (0,00%)
  - mp3 = 42 (0,24%)
  - usm = 161 (6,87%)
  - kraken = 2 (0,00%)
  - wwise (opus) = 149187 (7,20%)
  - wwise (vorbis) = 4962 (4,93%)

Time: 00:06:06 (CPU 00:43:47)

The rest is criware usm video and audio

Not possible with this.

lzma recompressing is headache. You need the exact settings and so on. I believe even delta patching is not possible afterwards like with zip.

You can compress extracted files with Asset Studio again? See if this works.

Can anyone share the proper compression method for the remastered version, the one for the next-gen edition isn't working

I tried the default LZMA settings in that SDK but they've used custom parameters and solid compression that gets decompressed into memory by the game so it would be virtually impossible to figure out and not worth the effort.
Thanks.

If it helps, I believe the lzma.exe version used was v4.57. I could probably brute force the params but it'd take a while.

92.8GB => 53.8GB

Time:

16:15:53 - Starting Data1.bin.001 creation
 3:13:01 - Finished Data1.bin.001 creation
 3:13:03 - Starting Data2.bin.001 creation
 3:20:28 - Finished Data2.bin.001 creation
 3:20:32 - Starting Data3.bin.001 creation
 3:25:44 - Finished Data3.bin.001 creation

Edit: You will get 52.3GB with BPK on *.vib files (rename them to *.bk2). Just make sure to exclude the 1kb files, they give unpack error.

Original size:   96.486g
Compressed size: 42.478g

Compression used: bpk+oo2reck+srep:m3f+4x4:lzma

PS: Make sure to not compress 72 bytes videos with bpk, they will give crc error (exclude them).

[Masquerade]

Beyond A Steel Sky uses ZSTD compression on the pak, but neither zstdrec nor xtool can inflate it.

Xtool:zlib will only inflate +0.44% over original size.

Any clues?
