Driver

  • Each GPU generation (GTX 16, RTX 20, 30, 40 and 50) is now described by the card itself: the driver reads the
    architecture and the newest engine classes from the GPU and publishes them, and the Metal driver picks the video
    decoder and the scan-out model from that instead of a table of device IDs
  • Cards with a small BAR1 (Resizable BAR off, or a board that does not offer it): the driver moves BAR1 away from the
    boot screen at its own size, so GTX 16 / Turing cards get the same zero-copy display path as the others. A BAR1 that
    macOS left unassigned is reported instead of failing with no reason
  • The desktop no longer waits for the GPU on every frame (#196): each window the compositor draws is marked when the
    GPU finishes it, and the display waits only for that mark
  • A BAR1 the firmware already placed large is left as it is, and the old setup comes back if a resize fails
  • Gamma tables are applied; HiDPI desktop modes can be turned on with nvfbhidpi
  • The installer keeps your own settings block in nvrm610.conf

Metal

  • Blender: Eevee renders lit scenes. NVIDIA GPUs cannot write the stencil value from a shader, which Blender's Metal
    backend relies on to sort its lighting; the driver now rebuilds that value by drawing once per stencil bit. Also
    fixed: a light loop that hung the GPU (the first active SIMD lane, and loop values lost when helpers were inlined),
    render passes with no attachments, layered 3D colour targets, framebuffer fetch, samplers held in argument buffers,
    and image atomics in helper functions. Blender's shadow pages no longer crash it
  • Indirect compute dispatches read their grid size on the GPU instead of stopping to read it on the CPU
  • Hardware video decoders are registered with macOS's decode service (#175)

AMD / Intel test driver

  • The log now says which driver started, which PCI drivers registered and which device each one matched, so a GPU
    no driver took can be traced from a user's log

Mac app

  • Map my GPU (experimental, opt-in)
