About

A client-side Fabric *.21.4 optimization mod focused on older integrated graphics and shared-memory systems. It enables conservative OpenGL backface and depth culling, keeps reusable thread-local transformation scratch buffers, provides a bounded worker pool for safe CPU-only preparation tasks, reduces allocation pressure, and restores renderer state cleanly around world rendering. The design avoids unsafe world mutations and preserves vanilla rendering correctness while targeting lower CPU overhead and smoother frame pacing.
