Unreal Engine currently supports Ray Tracing technology. However, this technology has a high performance cost when used alone. DLSS comes into play right here, allowing the AI to upscale the image from a lower resolution for higher frame rates with less visual distortion.
Features introduced as part of the Unreal DLSS plugin are as follows:
- Uncompromising quality with higher performance: Enjoy ray tracing and ultra-high resolutions with NVIDIA DLSS technology. It uses advanced AI processing to produce a better image quality, sometimes comparable to native resolution, while only making up a fraction of the pixels. New transient feedback techniques give you incredibly sharp image details and improved frame-to-frame stability.
- Customizable options: DLSS allows you to choose many image quality modes from quality mode to ultra performance. You can choose how you want to balance quality and performance by controlling the game's internal rendering resolution. Performance mode provides 4X artificial intelligence resolution (1080p -> 4K), while the new ultra performance mode provides 9X artificial intelligence resolution (1440p-> 8K).
