Changes

  • Sound on hot phones (#176). When a phone got hot and slowed its cores down, the sound crackled late in long races, and it could feel like slow motion, though the race itself kept real time.
    • Cause: the game's own sound thread fell behind on the slowed cores, so its mixer handed out silent frames. The output never ran dry.
    • Fix: on Android the game's sound threads now get the same priority as other audio apps, so they keep up when the cores slow down.
    • In testing: on an AYN Thor with the game's threads squeezed onto one little core, silent frames fell from about 280 to about 50–150 per 10 seconds, with no effect on race speed.
    • Switch: Test options › Processor › Sound threads first (on by default) turns it off.
  • For testing: game.log now counts silent audio frames, late audio callbacks and the output queue, to tell crackle causes apart.

Everything else is the same as v0.10.30.

Validation

  • AYN Thor, this release's APK:
    • Dolphin Resort at full speed (0.999, 60 fps).
    • Helpers held to a little core with sound on: race 0.986, sound threads raised (no error), silent frames 60–148 per 10 s.
    • Tilt to kick on: full speed.
  • Windows x64 package, Vulkan, with the validation layer and sound on: a whole race, no validation errors, all 455 pipelines, 0 silent audio frames.
  • macOS (M1) package: a whole Dolphin Resort race at full speed.
  • Unit tests: 171 passed on Linux. GitHub Actions builds and tests passed on Windows, Linux, macOS and Android.
  • Not tested on a real hot Pixel, which is where it matters; tell us in #176 if the crackle remains.
