r.FullScreenMode is a console variable in Unreal Engine 5 (UE5). See what r.FullScreenMode does, its values, and how to use this cvar in the Unreal console below.

Category: Renderer · Namespace: r

Help

Defines how we do full screen when requested (e.g. command line option -fullscreen or in ini [SystemSettings] fullscreen=true) 0: normal full screen (renders faster, more control over vsync, less GPU memory, 10bit color if possible) 1: windowed full screen (quick switch between applications and window mode, slight performance loss) any other number behaves like 0

Usage

Unreal console (open with ~)
> r.FullScreenMode 1

Console variables take a value. Replace 1 with the setting you need. Run it with no value to print the current one.
