Feb 1, 2025February 2025 performance summary for secondlife/viewer: delivered targeted improvements in avatar rendering, UI stability, and data handling, with a strong emphasis on responsive user experience and maintainability. Key avatar pipeline optimizations reduced LOD processing on the mesh thread, corrected mesh/cache handling, and accelerated nearby avatar loading after teleports, contributing to smoother scenes in crowded areas. UI/text rendering stability fixes improved consistency during screen transitions and supported multi-byte glyphs, reducing visual glitches. Inventory performance work reduced unnecessary content checks and throttled updates, boosting frame-time during asset fetches. Reliability improvements included voice reconnection fixes, crash-test expansions, and safer handling of references, increasing session stability. Cache strategy enhancements and naming optimizations further reduced startup and lookup latency while lowering memory pressure.
