By default, most lowlevel 2D APIs will use a triple buffer scheme that wastes no CPU time on waiting for
vsync after issuing a flip, but introduces a frame of latency. On the other hand, using a double buffer
scheme instead is recommended for cases where low latency is an important factor because we save a whole
frame of latency.
We do so by waiting for vsync immediately after issuing a flip, usually just after eglSwapBuffers call in
the backend's *_SwapWindow function.

• Raspberry Pi (raspberrypi)
• Wayland (wayland)
This hint should be set before SDL is initialized.
