SDL_HINT_GPU_DRIVER

A variable that specifies a GPU backend to use.

Header File

Defined in <SDL3/SDL_hints.h>

Syntax

#define SDL_HINT_GPU_DRIVER "SDL_GPU_DRIVER"

Remarks

By default, SDL will try all available GPU backends in a reasonable order until it finds one that can work, but this hint allows the app or user to force a specific target, such as "direct3d12" if, say, your hardware supports Vulkan but you want to try using D3D12 instead.

This hint should be set before any GPU functions are called.

Version

This hint is available since SDL 3.2.0.
