October 2025 performance summary for shadPS4-emu/shadPS4: Implemented Video-Audio Synchronization Enhancement in AvPlayer by removing the maximum audio delay check and using direct timestamp comparisons when an audio stream is present. This change simplifies synchronization logic, enables dynamic adjustments, and improves synchronization accuracy, leading to smoother audiovisual playback in emulation. The work strengthens user experience and lays groundwork for future AV-timing optimizations.

September 2025 monthly summary for shadPS4 project. Focused on delivering core playback reliability enhancements and audio decoding improvements. Key work includes Enhancements to AvPlayer playback controls and lifecycle, and RIFF header parsing support for AJM audio decoding. These changes improve playback reliability, enable proper initialization of RIFF-encapsulated audio formats, and enhance gapless playback. The work reduced risk of duplicate starts, ensured clean state transitions, and broadened supported audio formats, contributing to overall product stability and user experience.

March 2025 monthly summary for shadPS4-emu/shadPS4: Implemented cross-platform clock_gettime and PS4 clock ID mapping, delivering kernel-level time functionality across Windows and POSIX, enabling accurate time retrieval in emulation. This work lays groundwork for time-dependent features and improves cross-platform correctness. No major bug fixes this month; feature-focused delivery.

February 2025 (Month: 2025-02) focused on stability, performance, and dependency hygiene for the shadPS4 project. Delivered targeted fixes and optimizations that reduce noise, cut unnecessary processing, and ensure compatibility with latest libraries.

January 2025 monthly summary for shadPS4: Focused on improving issue triage tooling and rendering reliability, while stabilizing cross-arch builds. Delivered enhancements to the bug report template to guide troubleshooting, clarified scope (no modded games or patches) and introduced a log-attachment requirement to improve diagnostic quality. Fixed rendering correctness when clipping is disabled by updating the SPIR-V shader path, adjusting push data and viewport handling, and ensuring zmin/zmax depth ranges are respected across configurations. Refactored build tooling to use std::string_view for better cross-arch compatibility and potential efficiency. These changes reduced support cycles, improved issue reproducibility, and strengthened renderer reliability across configurations.
