This page documents every optimization patch Lomka applies, and how to toggle them
at runtime via config/lomka-mixins.properties.
The config file is created empty on first launch. Every line you add forces a single patch on or off:
# fully qualified mixin name=true|false
net.minecraft.core.MixinCursor3D=falseRules:
- Missing keys always mean enabled. You only need entries for patches you want to turn OFF. New mixins added by an update work automatically without editing the file.
- Only
true/1enable. Anything else (including typos likeflase) disables the patch; non-boolean garbage is reported in the log. - Keys that do not exist in your installed build are ignored and reported as unknown.
- Disabled patches are summarized at startup:
[Lomka/MixinConfig] Disabled 2 mixin(s): MixinCursor3D, MixinFont - Deleting the file restores the all-enabled default on next launch.
Warning: disabling patches reduces performance and may change behavior. The
accessor.* entries are internal access bridges used by other Lomka mixins keep
them enabled.
Supported game versions: 1.20.1 · 1.21-1.21.1 · 1.21.4 · 1.21.6-1.21.8 · 1.21.9-1.21.10 · 1.21.11 · 26.1-26.1.2 · 26.2
In the tables below, Versions shows which builds contain the patch: all means
every supported version, 1.21.6+ means that version and newer, and ranges like
1.21.6-1.21.11 are inclusive over the supported list above. A key outside your game
version simply does not exist in your jar the config loader ignores it with an
unknown key log line. Nothing breaks.
