Framerate

Render modes

Value
Description

Composited

The page is rendered off screen and its frames are drawn into the layout as an image. This keeps the transparency of the HTML, lets other elements be drawn on top of the browser, and makes it visible on NDI and Decklink outputs and on render windows with a transparent background. It accepts no mouse or keyboard input.

Native

The page is hosted in the native WebView2 window. This is the fastest mode and the page stays interactive, but the window always sits on top of all other elements, it is not captured by NDI or Decklink, and it stays invisible on windows with a transparent background.

Framerate, RenderWidth and RenderHeight only apply to Composited.
