GPU_backend_type_selection_detect()

bool GPU_backend_type_selection_detect

(

)

Detect the most suited eGPUBackendType.

• The detected backend will be set in GPU_backend_type_selection_set.
• When GPU_backend_type_selection_is_overridden it checks the overridden backend. When not overridden it checks a default list.
• OpenGL backend will be checked as fallback for Metal.

Returns true when detection found a supported backend, otherwise returns false. When no supported backend is found GPU_backend_type_selection_set is called with GPU_BACKEND_NONE.
