 r.Upscale.Quality=5            ;Defines the quality in which ScreenPercentage and WindowedFullscreen scales the 3d rendering. 0: Nearest filtering 1: Simple Bilinear 2: Directional blur with unsharp mask upsample. 3: 5-tap Catmull-Rom bicubic, approximating Lanczos 2. (default) 4: 13-tap Lanczos 3. 5: 36-tap Gaussian-filtered unsharp mask (very expensive, but good for extreme upsampling).
 
 r.SceneColorFormat=5       ;Defines the memory layout (RGBA) used for the scene color (affects performance, mostly through bandwidth, quality especially with translucency). 0: PF_B8G8R8A8 32Bit (mostly for testing, likely to unusable with HDR) 1: PF_A2B10G10R10 32Bit 2: PF_FloatR11G11B10 32Bit 3: PF_FloatRGB 32Bit 4: PF_FloatRGBA 64Bit (default, might be overkill, especially if translucency is mostly using SeparateTranslucency) 5: PF_A32B32G32R32F 128Bit (unreasonable but good for testing)

r.ViewDistanceScale=          ;Controls the view distance scale. A primitive's MaxDrawDistance is scaled by this value.
Higher values will increase view distance but at a performance cost. Default = 1.

r.SimpleForwardShading=1         ;Whether to use the simple forward shading base pass shaders which only support lightmaps + stationary directional light + stationary skylight. All other lighting features are disabled when true. This is useful for supporting very low end hardware, and is only supported on PC platforms. 0:off, 1:on

* Typically used for Console

r.ViewDistanceScale.ApplySecondaryScale=        ;If true applies the secondary view distance scale to primitive draw distances. Default = 0.

r.SecondaryScreenPercentage.GameViewportOverride=1            ;secondary screen percentage for game viewport.
0: Compute secondary screen percentage = 100 / DPIScalefactor automaticaly (default) 1: override secondary screen percentage.

r.ViewDistanceScale.SecondaryScaleControls=0.8             80% the secondary view distance scale, Default = 1.0.
This is an optional scale intended to allow some features or gamemodes to opt-in.
You can set the secondary screen percentage by using the following console variable in your configuration (.ini) file:
r.SecondaryScreenPercentage.GameViewportIf we know that the backbuffer resolution is 1080p, we can target a lower resolution of 900p by entering the percentage of that for the secondary screen percentage.
Target Resolution / Currently Set Resolution * 100 = Secondary Screen Percentage900 / 1080 * 100 = 0.8333 * 100 = 83.33For example, we use a value of 83.33 when targeting 60hz on Xbox One for Fortnite Battle Royale and set it by using the following:
[XboxOne_60 DeviceProfile]DeviceType=XboxOneBaseProfileName=XboxOne+CVars=r.SecondaryScreenPercentage.GameViewport=83.33Adding the secondary screen percentage to your config file will override the Editor and any platforms it is set for. Also keep in mind that using the console variable r.SetRes controls the backbuffer resolution. It's best to leave that at 1080p or 4k so that the UI always renders at native resolution for the target platform.
