    ProsperoLight 01.000.070 Pre-release

    archiver-bot released this 2026-09-30 20:44:42 -05:00 | 157 commits to main since this release

    Experimental performance beta — new decode and presentation threads

    This is a prerelease, not a replacement for stable 01.000.060. It
    supersedes beta 01.000.062.

    • Decoding and presentation now run on separate threads. Decoding no longer
      waits for a flip, and every display refresh shows the newest decoded frame.
    • A stream that outruns the decoder keeps playing at the decoder's pace. The
      rule that showed one frame every 100 ms once decoding fell behind is removed.
    • Stream threads are kept off the CPUs reserved for the decoder, and the video
      receive thread has a CPU of its own.
    • The flip wait uses flip events instead of polling or waiting for a vblank.
    • The overlay separates network, decoded and displayed frame rates, and frames
      lost on the network from frames discarded because decoding fell behind.
      Decode time covers the last second (mean, 95th percentile and load).
    • New settings: V-Sync (Off flips immediately and tears), Decoder
      pipeline       (Classic by default; Adaptive is experimental) and Decoder CPU
      cores       (3 by default; 4 and 5 are experimental).
    • Bitrate presets gain 50, 60 and 70 Mbps.
    • A failed stream now says whether the connection was lost while streaming or
      never completed, with the stage and the error code.
    • moonlight-common-c is updated, and the performance summary is also written
      to klog.

    Know the bitrate limit

    The PS5 decoder, not the network, limits the usable bitrate, and this beta
    does not raise that limit. Measured at 4K HEVC: smooth up to 80 Mbps at
    120 FPS and about 115 Mbps at 90 or 60 FPS; above 100 Mbps at 120 FPS and
    145 Mbps at 90 FPS the stream freezes about once a second. The table and chart
    are under Bitrate limits.

    What was tested

    Run on one PS5 with one NVENC host at 4K, 120 FPS, HEVC SDR, with both decoder
    pipelines. 1440p, 1080p, 60 and 90 FPS, HDR, H.264 and V-Sync Off use the same
    code but were not re-run on a console for this beta. The Adaptive pipeline had
    one defect fixed after its last console run; leave it on Classic unless you
    want to help test it.

    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.
    • The three new settings, and whether this beta is smoother, unchanged, or
      worse than .062 or .060 in the same game.
    • With the overlay on (Select+R1): the "Decoder", "Decode (last second)" and
      both "Frames dropped" lines.
    • 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 and settings are retained. To roll back, replace the beta with
    the corresponding .062 or .060 download and restart ShadowMountPlus or the
    console.

    Local reproduction:
    make ffpfsc FEC_SIMD=1 OPUS_SIMD=1 PERFORMANCE_DETAIL=1 FLIP_POLL_US=200 INPUT_POLL_US=2000 VIDEO_SLICES_PER_FRAME=8.

    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.

    Smoother 4K120 streaming

    • Enabled bounded decode/presentation overlap: the next picture can decode while
      the previous native flip completes, with at most one outstanding submission.
      Source surfaces and shared GPU memory remain protected until completion.
    • Improved stale-frame handling, short-window FPS metrics, and fractional-refresh
      negotiation (for example, a 120 FPS request on 119.88 Hz output).
    • Added a small local post-session performance summary and regression checks for
      presentation ownership, timeout handling, and incomplete report writes. No
      remote telemetry or streamed content is collected by this summary.

    4K120 before / after

    One paired Hollow Knight test on PS5 firmware 6.02, using wired Ethernet,
    3840×2160 at a requested 120 FPS, HEVC SDR, 80 Mbps, stereo, and 119.88 Hz output:

    Measurement Before: overlap off After: overlap on
    Decoded / presented frames 16,769 / 12,686 14,058 / 14,058
    Stale presentation skips 4,083 (24.3%) 0 (0%)
    Mean enqueue-to-decoder-callback wait 5.468 ms 0.016 ms
    Sampled pending video queue peak 5 frames 0 frames
    Mean decoder-call time 6.869 ms 6.934 ms
    p99 CPU-observed completion interval 75.499 ms 31.499 ms

    The tester reported lots of stuttering before and much smoother playback
    after    . Neither run reported network frame gaps or audio errors. The improvement
    is in queueing and presentation, not faster hardware decoding.

    These are whole-session measurements from one comparison, including startup and
    menus, with different session lengths. The baseline was instrumented with overlap
    disabled, not the exact public 01.000.055 binary. This is not a guarantee of
    locked 120 FPS, lower input-to-photon latency, or a fix for every high-bitrate/Wi-Fi
    setup. CPU-observed frame age increased from 12.560 to 16.854 ms; overlap changes
    when completion is observed, and the baseline excludes skipped pictures from
    that metric. It cannot establish an end-to-end latency change.

    See the Round 2 measurements and methodology.
    Further performance work is deferred to the next version: FEC SIMD, Opus SIMD,
    audio catch-up, and shorter flip polling are not enabled in this release.

    Installation / update

    Title ID remains PPSA99002; existing pairing and preferences are preserved.
    Choose PPSA99002.ffpfsc or extract PPSA99002.zip and copy its PPSA99002/
    folder to /data/homebrew. Do not keep both formats installed for the same
    title. Close the app before replacing its files, then restart ShadowMountPlus
    or the console. SHA256SUMS covers both downloads.

    archiver-bot released this 2026-09-01 06:33:50 -05:00 | 175 commits to main since this release

    • Added a persistent Stereo / 5.1 surround setting.
    • Added Moonlight-compatible 5.1 Opus negotiation and PS5 eight-channel AudioOut,
      with the unused side channels silenced and automatic stereo fallback when the
      surround port is unavailable.
    • Compacted the Settings rows so all seven controls and the shortcut note remain
      visible above the footer.
    • Replaced the temporary demo app cards with a clear loading state while the
      Sunshine application catalog refreshes.
    • Unified the mbedTLS structure configuration across the C and C++ stream code,
      preventing identity initialization from overwriting the live PS5 pad state.

    Changelog

    01.000.050

    • Added independently selectable 90 and 120 FPS streaming at 1080p, 1440p,
      and 2160p, with native 4K/119.88 Hz output validated on PS5 hardware.
    • Preserved native 4K presentation for high-resolution HFR streams and restored
      the launcher output cleanly when a stream ends.
    • Added an application-side startup transition for TVs that resynchronize when
      an HFR-capable title opens.
    • Moved Sunshine discovery behind the first rendered launcher frame for faster
      visible startup.
    • Documented that HFR setting changes should be applied before launching, or
      followed by stopping and relaunching the active Sunshine application.
    • Clarified that wired Ethernet is recommended for high-resolution and HFR
      streaming.
    • Added guidance to tune bitrate per configuration because maximum bitrate can
      reduce smoothness at 4K or high frame rates.
