WisAdapterPreference Struct Reference

Detailed Description

Specification

---

To select order of adapters use:

C version:

// Provided by Wisdom 0.7.0.
typedef enum WisAdapterPreference {
    WisAdapterPreferenceNone = 0,
    WisAdapterPreferenceMinConsumption = 1,
    WisAdapterPreferencePerformance = 2,
} WisAdapterPreference;

C++ version:

namespace wis{
// Provided by Wisdom 0.7.0.
enum class AdapterPreference {
    None = 0,
    MinConsumption = 1,
    Performance = 2,
};
}

Description

---

Orders the adapters according to preference using builtin heuristics of underlying APIs. For DirectX 12, this translates directly to DXGI_GPU_PREFERENCE. For Vulkan, sorting is based on VkPhysicalDeviceType heuristics.

Note

Translates to DXGI_GPU_PREFERENCE for DirectX 12 implementation.

Values:

• WisAdapterPreferenceNone = 0: No particular preference, list adapters in system devised order.
• WisAdapterPreferenceMinConsumption = 1: List the adapters from low power consumption to high. DirectX 12: Integrated, Discrete, External, Software. Vulkan: Integrated GPU, Discrete GPU, Virtual GPU, CPU.
• WisAdapterPreferencePerformance = 2: List the adapters from high performance to low. DirectX 12: External, Discrete, Integrated, Software. Vulkan: Discrete GPU, Integrated GPU, Virtual GPU, CPU.

GPU order may vary between the implementations due to differing heuristics.
