NVIDIA has recently launched the DLSS 4 plugin for Unreal Engine 5.6, enabling developers to integrate the company's cutting-edge upscaling and AI-driven frame generation tools into their projects. This update brings the performance enhancements of UE 5.6, including optimized memory management and refined rendering pipelines, together with Transformer-based upscaling. This technology reduces VRAM usage while creating additional frames to enhance motion smoothness.
Developers working with Unreal Engine 5.6 now have the ability to incorporate multi-frame generation, ray reconstruction, deep learning anti-aliasing, and super resolution into their projects using a single, resource-efficient package. This new version of DLSS requires fewer resources compared to previous iterations.
The DLSS 4 plugin utilizes a Transformer neural network that analyzes the relationships between all pixels in a frame, rather than relying on localized convolutional filters. This approach reduces video memory requirements by around 15-20% compared to the previous DLSS 3 SDK, allowing for higher-resolution textures and more detailed environments. Multi-frame generation predicts intermediate frames based on recent frame history, effectively increasing perceived frame rates without additional GPU draw calls.
Ray reconstruction improves reflections and global illumination by learning from high-quality offline renders, resulting in realistic lighting with minimal impact on performance. Initial feedback suggests a 30-50% improvement in ray-traced effects quality in GPU-bound scenes, as well as sharper visuals under dynamic lighting conditions. The plugin is compatible with Unreal Engine versions 5.2 through 5.6, but the full range of enhancements is only accessible for projects running on version 5.6.
