Anyone knows what zstd lib to use? It's slow af

Unsure, I have checked with latest ZSTD to see if it can list info about the archives, yet it can only seem to load info for few archives. Yet, all files are definitely compressed with zstd.

for %f in (*.arc) do zstd -l "%f"

I even tried compressing a demo file with zstd and testing the latest libzstd to see if the precompressor worked, neither zstdrec or xtool could precompress a random file compressed with latest zstd.
