Enum PresentModePref 

pub enum PresentModePref {
    Auto,
    Fifo,
    Mailbox,
    Immediate,
}

Preferred GPU present mode for windowed rendering.

The renderer picks the closest supported mode from the surface capabilities, falling back to an “auto” Fifo-first selection when the preferred mode is unavailable.

Variants

Auto

Limit to display refresh using vsync: prefer Fifo, then Mailbox, then Immediate. This is the default and matches the renderer’s historical behavior.

Fifo

Vsync, always wait for the next vblank (no tearing). Falls back to Auto if unsupported.

Mailbox

Low latency, waits for the vblank only when a new frame is available (no tearing). Falls back to Auto if unsupported.

Immediate

Present immediately without waiting (may tear). Useful for uncapped low-latency rendering. Falls back to Auto if unsupported.
