Added optimize options to speed up the decoding process for zstd and oodle, which helps in faster installation.

: The FileForums Compression section is the primary hub where Razor12911 and other repackers (like FitGirl) discuss scripts and updates. Added optimize options to speed up the decoding

In a typical repack (e.g., ), Xtool helps reduce a 55GB original release to roughly 29GB.

: Because it is designed for speed, Xtool often uses 100% of your CPU. This is normal behavior during the "Decompressing" stage of a game installation. Installation Hangs : Because it is designed for speed, Xtool

xtool (and its predecessor, ) was developed by Razor12911 to solve the "pre-compressed data" problem. It functions as a pre-compression library .

A "history data" feature allows the library to recognize repeated game resources, preventing the tool from re-processing identical streams multiple times.

It supports a wide array of modern game engine codecs, including Oodle (Kraken, Mermaid), Zstd, LZ4, and even specialized filters for textures and media.
