Jets 'n' Guns 2

Playable · Completable

Concurrent music and effects now keep separate host streams. The October 9 development fix also preserves PCM order after an underrun; it is newer than release 0.3.4. The maintainer confirmed a complete playthrough on September 15.

What works

  • Complete playthrough confirmed by the maintainer.
  • Levels, HUD, score, enemies and parallax layers all draw correctly.
  • Music and effects no longer compete for one output device.

What does not

  • A final 30-second installed-runner menu recording retained one 30 ms silent interval; its cause is not established.
  • Short menu and combat audio checks passed; end-to-end sound latency and long-session stability were not measured.

Measured performance

October 9 combat UI samples read 35.7–45.8 FPS. The historical 70–92 ms frames (11–14 FPS) used an earlier build and scene; this is not a matched speedup benchmark.

    Independent music and effects streams; audio retested

    A 20-second mission-menu loopback recording fell from 92.25% silent 10 ms blocks on 0.3.4 to zero with the fix. Two 13-second active combat intervals also had no silent blocks. Full recordings include silence at transitions and after player death. Separate host streams replace device handoffs, and recovery now wraps within the active PCM ring. All 596 HLE tests passed. This is a development fix after 0.3.4, not a new complete playthrough or a controlled FPS comparison.

  2. Release 0.3.2Vulkan

    Audio stops tearing itself down

    Two active output ports had been competing for the host audio device, tearing down the mix and reopening the device several times per frame. Release 0.3.2 fixed the routing; the existing playable and completable status was unaffected.

    START GAME reaches 4K tutorial gameplay

    Title content resolved, AGC resource registration completed, and the full graphics, compute and output loop sustained. START GAME got past the loading screen into recognisable 3840×2160 tutorial gameplay, and an unattended run stayed live past flip 300.

    Playable and completable

    The maintainer confirmed a full playthrough. Levels, HUD, score, enemies and the parallax scene all render correctly. Profiling a 70 ms frame found 18 ms waiting on the GPU across 33 submissions, 11 ms on resource checkpoints and 13 ms staging 894 guest buffers.
