SDL_GPUPresentMode(3type)

NAME
SDL_GPUPresentMode - Specifies the timing that will be used to present swapchain textures to the OS.

SYNOPSIS
#include <SDL3/SDL_gpu.h>

typedef enum SDL_GPUPresentMode
{
    SDL_GPU_PRESENTMODE_VSYNC,
    SDL_GPU_PRESENTMODE_IMMEDIATE,
    SDL_GPU_PRESENTMODE_MAILBOX
} SDL_GPUPresentMode;

DESCRIPTION
VSYNC mode will always be supported. IMMEDIATE and MAILBOX modes may not be supported on certain systems.

It is recommended to query SDL_WindowSupportsGPUPresentMode after claiming the window if you wish to change the present mode to IMMEDIATE or MAILBOX.

• VSYNC: Waits for vblank before presenting. No tearing is possible. If there is a pending image to present, the new image is enqueued for presentation. Disallows tearing at the cost of visual latency.

• IMMEDIATE: Immediately presents. Lowest latency option, but tearing may occur.

• MAILBOX: Waits for vblank before presenting. No tearing is possible. If there is a pending image to present, the pending image is replaced by the new image. Similar to VSYNC, but with reduced visual latency.

AVAILABILITY
This enum is available since SDL 3.2.0.
