Enum bevy::window::PresentMode
[−]#[repr(C)]
pub enum PresentMode {
Immediate,
Mailbox,
Fifo,
}
Expand description
Presentation mode for a window.
The presentation mode specifies when a frame is presented to the window. The Fifo
option corresponds to a traditional VSync
, where the framerate is capped by the
display refresh rate. Both Immediate
and Mailbox
are low-latency and are not
capped by the refresh rate, but may not be available on all platforms. Tearing
may be observed with Immediate
mode, but will not be observed with Mailbox
or
Fifo
.
Immediate
or Mailbox
will gracefully fallback to Fifo
when unavailable.
The presentation mode may be declared in the WindowDescriptor
or updated on a Window
.
Variants
Immediate
The presentation engine does not wait for a vertical blanking period and
the request is presented immediately. This is a low-latency presentation mode,
but visible tearing may be observed. Will fallback to Fifo
if unavailable on the
selected platform and backend. Not optimal for mobile.
Mailbox
The presentation engine waits for the next vertical blanking period to update
the current image, but frames may be submitted without delay. This is a low-latency
presentation mode and visible tearing will not be observed. Will fallback to Fifo
if unavailable on the selected platform and backend. Not optimal for mobile.
Fifo
The presentation engine waits for the next vertical blanking period to update
the current image. The framerate will be capped at the display refresh rate,
corresponding to the VSync
. Tearing cannot be observed. Optimal for mobile.
