Probably you will get more out of it using lolz, because 90% of the game consists of tga/dds images..

xtool+srep+lolz

On *.webm and *.feral

srep+lzma2

*feral is ogg audio archives, so you could use oggre but no idea of the benefit (or any issue in decompression)

50.1GB ----> 17.3GB

Optimal Packing

JPG files and use: -mbrunsli or -mlepton
Sound Folders = msc+srep+lzma
PNG+GIF = precomp+srep+lolz

everything else = reflate+srep+lolz_ldmf=d1023m:mt2


Lossy Section:
Run this script to all webm files, you get 25% of the original size
so for 1GB of raw video you get 250mb.

ffmpeg -i "webm_files" -c:v libvpx-vp9 -b:v 2000k -c:a opus -b:a 112k -y "output_webm_files"

I Attached Brunsli:

[External compressor:brunsli]
packcmd = brunsli_x64 c $$arcdatafile$$.jpg $$arcdatafile$$.brn
unpackcmd = brunsli_x64 d $$arcdatafile$$.brn $$arcdatafile$$.jpg
datafile = $$arcdatafile$$.jpg
packedfile = $$arcdatafile$$.brn
solid = 0

Visual Paradigm of trully eye lossless Compression:
Lossless: https://drive.google.com/file/d/18O_...ew?usp=sharing
Lossy: https://drive.google.com/file/d/1QmL...ew?usp=sharing

Just FYI, game sounds + eng only packing:

srep+LZMA2 = 927MB

msc+srep+LMA2 = 886MB

41mb space savings.

Xprecomp is an arc.ini command line introduced from the original version of xtools that razor released..
i had the command line tied into the zlib fuction at the time i did that
so pretty much i used the zlib function on xtools

Total War ROME RemasteredTotal War ROME Remastered How To Reduce The Size Of Gaming Videos Without Disrupting Quality

Could it be possible to show it as a sample Video ?

Has anyone given "PC Building Simulator" a try? Tried compressing with msc + srep + lolz but unfortunately got a "-1" FreeArc archive corruption error at around 1.2% into attempted installation. Not sure if there's a trick to these Unity titles but it seems I'm yet to figure them out.

I'm not sure as to what is causing issues as I was able to get from 26gb to ~4gb so I'm certain the files can't already be compressed. Whats stranger is similar methods with the title "Outward" gave me similar final ratios, however "Outward" was able to decompress properly. My guess is that this might be an engine version issue, or with how Unity creates its packed files, but I'm honestly at a loss.

PC Building Simulator is just srep+lolz. Not sure why you're using msc.

L33THAK0R: This error message used Arc.exe from decompression?? Its probably used bad arc/cls.ini configuration or/and missing/wrong external exe/dll files these unpacking process.

Total War - Rome Remastered

Game Hierarchy Thanks to Fitgirl.

Textures that are TGA aka Targa files use lz4 compression that means that we need lz4 precompressor made to decompress TGA files
She has unpacked them all and made Xdelta patches

Movies > Simple Compression Can be Redone Using This:

PNG GIF FERAL and JPG Files she has used PRECOMP 0.47
MSC+SREP+lolz

Models*.pak > srep+lolzi

Executables srep+lzma.

If Targa files can be precompressed it's possible to make this game as low as 11 GB

Can we know what methods are used just from the .bin/.arc file?
