SDL_SetWindowSurfaceVSync - Man Page

#include <SDL3/SDL_video.h>

bool SDL_SetWindowSurfaceVSync(SDL_Window *window, int vsync);


#define SDL_WINDOW_SURFACE_VSYNC_DISABLED 0
#define SDL_WINDOW_SURFACE_VSYNC_ADAPTIVE (-1)

When a window surface is created, vsync defaults to SDL_WINDOW_SURFACE_VSYNC_DISABLED.

The vsync parameter can be 1 to synchronize present with every vertical refresh, 2 to synchronize present with every second vertical refresh, etc., SDL_WINDOW_SURFACE_VSYNC_ADAPTIVE for late swap tearing (adaptive vsync), or SDL_WINDOW_SURFACE_VSYNC_DISABLED to disable. Not every value is supported by every driver, so you should check the return value to see whether the requested setting is supported.
