    ProsperoLight 01.000.060 Stable

    archiver-bot released this 2026-09-09 23:18:05 -05:00 | 169 commits to main since this release

    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.
