Red Dead Redemption (Test)

Files Test (381MB)

"mapres.rpf"
"blackwater.rpf"

Method ZSTD (ZSTD file attached)

-mzstd,l19

Result

FreeArc 0.67 (March 15 2014) creating archive: ZAZA.Test.bin
Compressed 2 files, 399,803,872 => 1,213,731,228 bytes. Ratio 303.58%
Compression time: cpu 0.61 sec/real 44.09 sec = 1%. Speed 9.07 mB/s
All OK

You can use Zlib+Zstd and get some streams

-mzlib+zstd,l19

FreeArc 0.67 (March 15 2014) creating archive: ZAZA.Test.bin
Compressed 2 files, 399,803,872 => 1,224,533,926 bytes. Ratio 306.28%
Compression time: cpu 0.61 sec/real 46.82 sec = 1%. Speed 8.54 mB/s
All OK

You can use Xtool Ver 0.4.3 to Ver 0.6.0 all works fine with ZSTD

Dear ZAZA4EVER
I tried all versions of Xtool from 0.4.0 to 0.6.9 , with zstd but none of them gave me a ratio of more than 100% , I also tried with the libzstd.dll shared by you , but that didn't also work.
Kindly help me out.
Or can you share the Xtool version that you used , to compress the game with it's arc.ini file 🙏

It's all in the levels, re-read ZAZA4EVER's post and you will see that you need to lock XTool's precompressor at ZSTD level 19.

-mzstd,l19

Thanks Masquerade , it's working now
Earlier I was using -mzstd,l19 but it didn't work
Then I tried -mzlib+zstd:l19 & it worked
