    Experimental performance beta — help test 4K120

    This is a prerelease, not a replacement for stable 01.000.060.
    Improved decode headroom; remaining 4K120 stuttering is under investigation.

    • Requests eight slices per frame for increased decoder parallelism. Local HEVC
      tests confirmed eight slices and lower decode times, including comparable
      compressed-frame sizes. Gameplay windows included Windows/RDP login transitions:
      these are promising observations, not a controlled percentage improvement.
    • Shortens input polling to a 2-ms target and accounts for polling work time.
      This does not establish a measured input-to-photon latency reduction.
    • Enables CPU-feature-checked FEC SIMD and Opus SIMD, with 200-us flip polling.
    • Reduces repeated GPU cache-flush work and avoids heap allocation for common
      socket polls. Preserves bounded presentation overlap and source ownership.
    • Includes local performance summaries and bounded per-frame timing records for
      diagnosis. No streamed images, typed text, or automatic remote telemetry.
    • Includes PC removal/re-pairing improvements for changing host software.

    Decoder depth stays one, worker affinity/priority remain unchanged, every
    decoded picture remains eligible for presentation, and experimental pacing and
    audio-backlog dropping are off. No host configuration is modified. Eight
    slices may behave differently with other encoders/codecs; report regressions.
    Higher bitrate is not higher FPS, and sustained 120 FPS is not guaranteed.

    Please report your results

    Use GitHub issues and include:

    • PS5 firmware; Sunshine/Vibepollo version; host GPU and driver.
    • Codec/HDR, resolution/FPS, bitrate, stereo/5.1, Ethernet or Wi-Fi.
    • Game and whether this beta is smoother, unchanged, or worse than .060.
    • Complete Windows/RDP login first, reconnect, then warm up for 30 seconds and
      play the same area for two minutes. Return with Select+L1 and close the app.
      Separate login/menu/teardown time from gameplay. Stop early if unusable.
    • If available, attach performance-last.json and performance-frames.csv from
      the app's /download0/moonlight/ save directory. These are overwritten by the
      next stream; the console may expose them inside the title's UFS2 download0.dat.
      Do not upload the entire save image: it may contain pairing credentials.

    Installation, update and rollback

    Title ID stays PPSA99002. Choose PPSA99002.ffpfsc, or extract
    PPSA99002.zip and copy its PPSA99002/ folder to /data/homebrew.
    Do not keep both formats installed. Close the app before replacing files, then
    restart ShadowMountPlus or the console. SHA256SUMS covers both downloads.
    Existing pairing/settings are retained. To roll back, replace the beta with
    the corresponding .060 download and restart ShadowMountPlus or the console.

    Local reproduction (ordinary make retains conservative development defaults):
    make ffpfsc FEC_SIMD=1 OPUS_SIMD=1 PERFORMANCE_DETAIL=1 FLIP_POLL_US=200 INPUT_POLL_US=2000 VIDEO_SLICES_PER_FRAME=8.
