    [VideoOut] Prefer NVIDIA/discrete GPUs over integrated (#97)

    Ghost released this 2026-07-13 08:05:59 -04:00 | 513 commits to 1016_part3 since this release

    SelectPhysicalDevice took the first device exposing a graphics+present
    queue. On hybrid-graphics laptops that is the integrated GPU, so the
    discrete card went unused - and AMD's integrated driver access-violates
    inside vkCreateGraphicsPipelines while compiling some translated guest
    shaders, killing the process. The CLR surfaced that native AV as
    "Invalid Program: attempted to call a UnmanagedCallersOnly method from
    managed code", which made it look like a CPU/threading fault.

    Score the candidates instead: NVIDIA parts win, other discrete GPUs come
    next, and an integrated GPU is only chosen when nothing else can present.
    SHARPEMU_VK_DEVICE= pins a specific adapter, and the selected
    device is logged.
