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

[KaktoR]

-hash- just means there will be no crc check for srep. I added it because freearc already do this, so there is no need to make two crc checks, which will slow down things a bit.

For pathologic3 :

data1: xtool:c32mb:munity,lz4hc,l12:dd3+LOLZ_NORMAL
data2: xtool:dd3+bcm or xtool:dd3+bzip3
data3: xtool:mzlib:mpreflate+srep_new:490g+razor

there is some .bank files, can be processed outdside diskspan.
My results with the last game update 26.5gb

Is there no way to disable 2nd pass ?

I know splitting file into multiple archives causes increase in size but how much exactly ? I splitted Black Myth Wukong into 4 and the final size is almost 102 whereas it should be around 96-97, or did i mess up some other thing? Used -d96m/128m -mtt1 -mt10 -mc1023 for lolz. Precompression as per wareck. Another thing I noticed that DODI used oo2reck+oo2recm and got to 94.95GiB with a single archive

what do you mean splitting ? cls-diskspan split archive ? or splitting the game files into different archives to use different compression on them? like this one

Pre-processing:

inside Paladin\Content\FMOD\Desktop you will find many .bank files.
extract all of them using bnkextr. you will find a lot of .ogg and some
other files. merge all *.ogg files into a single solid file solid.ogg using
bincat or anything else. delete the rest of the extracted files. make a
hdiff patch from solid.ogg to Paladin\Content\FMOD\Desktop without
any compression.

Archives:

• Archive 1 - Paladin\Content\Paks\Paladin-WindowsNoEditor.pak
  use oodle dll v2.9.5
  

  xtool:mermaid+kraken+srep+lolz

• Archive 2 - *.mp4 *.mov
  

  zstd, or you can use bz3 (better ratio but slower unpack)

• Archive 3 - solid.ogg
  

  oggre

• Archive 4 - diff file
  

  msc:raw:wav

• Archive 5 - everything else
  

  dispack070+delta+razor

Final Size

input       -> 11,429 MB
compressed  ->  7,620 MB

splitting the game files into different archives.....though i used same method for all of them just had to do because of storage

thats valid. size increased because you split the games on 5 different 20 gb (i guess) archives. and compressed them separately. if you had compressed 100gb at once in a single archive you would atleast get "a little" better results. this goes for almost any data.

Yeah I have known that too, but for Black Myth Wukong I splitted 138GB into 4, 44.6,43.6,31.8 and 18, but the size is almost 6GB bigger than expected, that's why I was if this were because of the split or something else

used this for precomp with oodle 2.9.5

Splitting the data up like this will result in duplicated data not being sufficiently removed, thus greater final archive size.

Got it, will try redoing it then : ((

[wareck]

for now for Black Myth Wukong the best i've done is 96.9Gb
(full game, with optional bonus)

xtool:c32mb:d1:mkraken:mmermaid:core_2.9.5+srep_ne w:490g+LOLZ_NORMAL

Data1 is all .pak
Data2 all other

I do not use mue4 because it makes installation very slow and some time crc error
(yes it's mue4 n mue5 do not work for this game )

I'm working on a new test, with bk2 extracted form pak16. just to check if give better ratio

Can anyone share best compression method for Stellar Blade ?
