It looks like v2.9.12 library is the correct one here, at least for the sample I have.

You have to specifiy oodle kraken level, otherwise precompression will took forever.
Sample: gameresources_0_hq_patch1.streamdb

xtool:mkraken,l6
Compressed 1 file, 71,132,775 => 139,054,190 bytes. Ratio 195.49%
Compression time: cpu 0.05 sec/real 6.76 sec = 1%. Speed 10.52 mB/s
All OK

xtool:mkraken
Compressed 1 file, 71,132,775 => 139,054,190 bytes. Ratio 195.49%
Compression time: cpu 0.06 sec/real 12.88 sec = 0%. Speed 5.52 mB/s
All OK

However not all streams can be processed. Either all of the libraries I have are not the correct ones or this is one of the games which requires at least two different libraries to get all streams. I guess the latter is the case here, same as in games like WWE2K19 or Elden Ring.
Because it's idtech engine it is a bit tricky here. I looked through and I don't think plugin is possible, at least not configuration based.

Edit: Looks like resources files are kraken level 4 and you need another library for these files. Like I assumed, I guess it's the same as in other games. Two different libraries for the game files. For resources files it looks like library v2.9.0 is the way to go. The library does not work for streamdb files of course.

Edit 2: Here is the deal.

streamdb - kraken l6 - oo2core_9_win64.dll (2.9.12_2) CRC FCBE6F2C
streamdb (hq) - kraken l6 - oo2core_9_win64.dll (2.9.12_2) CRC FCBE6F2C
resources - kraken l3/l4/l6 - oo2core_9_win64.dll (2.9.13_6) CRC 41AAB7C9 (from game folder)

If I remember (i do not keep this game) :
file with HQ (high quality textures) have an specific oodle library and the other files of game have the other one.

I used a specific data file for HQ and install them as an optional feature.
I also use a bms script to extract wem files and keep only my language.

With only english and french , without HQ textures and bonus I'm at 56.9gb

What I've found out so far:

streamdb - kraken l6 - oo2core_9_win64.dll (2.9.12_2) CRC FCBE6F2C
streamdb (hq) - kraken l6 - oo2core_9_win64.dll (2.9.12_2) CRC FCBE6F2C
resources - kraken l3/l4/l6 - oo2core_9_win64.dll (2.9.13_6) CRC 41AAB7C9 (from game folder)

However some of the smaller hq patch files works better with the oodle library from game folder.

Average idtech engine experience.

Edit:
resources files

To make srep dedup takes effect for all the files, you have to use xtool as a standalone compressor without freearc and place freearc as a second step after xtool. Otherwise you will miss a load of duplicates if you precompress the files separately.
