Metro Exodus Precompression Tool

[Razor12911]

Another lz4 game in the bag as requested

I rushed this release, something came up and got busy. I ran one test and compared it with metro-vfx-unpacker and it seems like some streams are left behind.

test on patch_01.vfx (patch_01.vfs0, patch_01.vfs1):
using vfxrec 4.85 GB (5,215,404,338 bytes)
using metro-vfx-unpacker 5.29 GB (5,690,004,897 bytes)

That's all I can do for now :(

Extracted 3 files, 5,215,404,078 => 3,369,431,485 bytes. Ratio 154.79%
Extraction time: cpu 7.53 sec/real 196.03 sec = 4%. Speed 17.19 mB/s

Probably R2 will be able to detect everything. :)

Running a few tests before update is released

Update available

Changes

- Scanner updated to find all lz4 streams the game has (I think)

Notes

The files in vfx_data directory should be present ONLY during encoding and you should get this result when inflating
Compressed 70 files, 77,548,153,037 => 108,796,991,535 bytes. Ratio 140.30%
Compression time: cpu 131.33 sec/real 3361.83 sec = 4%. Speed 23.07 mB/s

all *.vfs# files except

// use a different liblz4.dll to get 102GB instead of 101GB
Compressed 70 files, 77,548,153,037 => 109,700,728,480 bytes. Ratio 141.46%
Compression time: cpu 92.30 sec/real 1173.97 sec = 8%. Speed 66.06 mB/s

There are 5 streams in this game that take about 60-90 seconds each to recompress. (cpu usage will be at its minimum during this)

// I noticed a lot of ogg headers in the game files, so maybe consider oggre (maybe it will work)

After working on this for 2 days I've come to a conclusion, fuck these lz4 compressed games. :mad:

Does not precompress anything for me

Compressing 283 files, 80,582,727,204 bytes. Processed 10.0%
Compressing 80,582,736,816 bytes with "srep_x64" -m3f -a0/0 InFile OutFile

So I assume I have to split all the files rather do the job for the whole folder. Sad :(

i have put alot of effort to find this game's data struc. there are alot of ogg files in it.

Basically its OGG only high quality as well.

there is 2 options, either that precompressor can opt out the data or we must zero out. for maximum compression ratio.

i just reinstalled the game and ran a test with all files (no splits) and it worked. :confused::confused::confused:

False alarm :D

My problem was I didn't include the vfx folder aswell. Oh boy.:rolleyes:

For Enhanced Edition of this game, you'll need to generate new vfx_data files because the vfx_data in the main post contains header information for the standard game before the ray tracing update with high resolution textures.

to do that, you'll need to use vfxgen
vfxgen GamePath LogFile

Use the newly generate files on the game files.

Notes

Use metro-vfx-tool (https://zenhax.com/viewtopic.php?t=9523) to generate new log files if the game has been updated or if the uploaded log files seem to not work.
