Asterix & Obelix: Slap Them All!

Playable · Completable

A confirmed playthrough. Gameplay and interface draw the right way up, and intro playback works. The final fullscreen composite stays on the GPU, and scanout keeps the guest viewport's orientation without copying a frame back through host memory.

What works

  • Complete playthrough confirmed by the maintainer.
  • Intro video plays, and gameplay and UI are correctly oriented.
  • A 3,000-flip development run finished without a single rejected submission.

What does not

  • Frame cost depends on scene density rather than being locked.

Measured performance

October 9 development retest: stationary opening-forest median 46.45 → 162.20 FPS, from 30-second UI-counter samples at 1080p output on RTX 3070 Ti. Later levels are not measured.

    MSAA depth/stencil fix raises opening-forest FPS

    The October 9 development build preserves the sample count in depth/stencil-only passes, restoring stencil masks and removing four accidental full-frame readbacks per frame. Stationary opening-forest UI-counter medians rise from 46.45 to 162.20 FPS in 30-second samples on the RTX 3070 Ti at 1080p output. Movement and the first Roman encounter are rechecked. All 233 Vulkan tests and native 2×/4× probes pass. This is a shared renderer fix after 0.3.4, not a minimum across all levels or a new full playthrough.

  2. Asterix gameplay after the watched video-buffer startup fix
    Development buildVulkan

    Opening movie no longer stalls on reused video buffers

    The October 9 development fix restores startup with GPU page tracking enabled. The old reader wrote FFmpeg output directly into guest video pages that had become read-only after texture upload, so playback stalled on the third frame. Video and audio now use the existing host pipe buffer before publishing tracked guest writes. The retest passes the bumper and reaches gameplay. All 597 HLE tests pass. This fix postdates 0.3.4; the earlier confirmed playthrough grade is retained.

    Release 0.3.0-alpha.4Vulkan

    Playable and completable

    A confirmed playthrough at 28–31 ms per frame, with a 3,000-flip development run free of rejected submissions. The fullscreen composite stays GPU-resident, and scanout preserves the guest viewport's orientation without a host-memory round trip.
