!lag

!lag 3.0.0 (Minecraft 26.3)

Tested in the real game (title screen, world load, all 17 mixins active, settings screen, benchmark, long-distance teleport) before release.

• Chunk compile budget (default on): caps section recompiles scheduled per frame to smooth CPU spikes when many sections rebuild.
• Terrain LOD compile defer (default on): skips re-meshing distant sections that already have a mesh while the compile queue is busy.
• Entity extract throttle and subpixel entity cull (default on): less CPU spent on far or tiny entities.
• Block entity extract skip, particle fast extract, fog buffer cache and lightmap extract cache (default on): skip redundant work when nothing changed.
• Adaptive render distance (default off): lowers render/simulation distance when FPS stays below a target.
• 30 second benchmark: /notlag benchmark or Performance tab > Run 30s benchmark reports average FPS and 1% low from real frame times.
• Diagnostics tab lists which optimizations are active.
• Honest note: in our software-rendered test machine we did not measure a clear FPS gain over 2.2.0, so treat these as CPU-load savers in busy scenes rather than a big FPS boost.
