Mount & Blade II Bannerlord
Seems like tpac files use lz4hc level 12. On this level you will get low streams but output is much bigger then with other levels.
Code:
Compressed 1 file, 7,120,255 => 14,068,315 bytes. Ratio 197.58%
Compression time: cpu 0.00 sec/real 30.88 sec = 0%. Speed 0.23 mB/s
All OK
However it is slow af
