# SDL_GPUPresentMode

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

## Header File

Defined in [<SDL3/SDL_gpu.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_gpu.h)

## Syntax

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

## Remarks

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

It is recommended to query
[SDL_WindowSupportsGPUPresentMode](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.

## Version

This enum is available since SDL 3.1.3
