If the rendering time still does not hit your target, you might want to use the secondary upscaler controlled by (r.SecondaryScreenPercentage.GameViewport). Please see this document (https://dev.epicgames.com/documentation/en\-us/unreal\-engine/screen\-percentage\-with\-temporal\-upscale\-in\-unreal\-engine\#secondaryspatialupscale) for more detail. We use it to achieve 60fps on XBOX One for Fortnite.
