NVIDIA has released its DLSS 4 plugin for Unreal Engine versions 5.5 and 5.6, giving developers expanded access to the company’s most advanced AI-powered upscaling tools.

DLSS 4 (Deep Learning Super Sampling) first launched alongside the GeForce RTX 50 Series GPUs in January, introducing a major leap in real-time rendering and performance optimization. The technology taps into NVIDIA’s new Transformer-based AI model—now out of beta—to deliver smoother visuals, higher frame rates, and improved image quality across compatible games. While some DLSS 4 features remain exclusive to RTX 50 GPUs, the core functionality supports all RTX cards, making it broadly accessible to developers working on performance-heavy titles.

According to NVIDIA, the plugin is designed specifically for Unreal Engine versions 5.5 and 5.6, which previously lacked official support. With this new release, game creators using the latest versions of UE5 can integrate DLSS 4 features like Frame Generation, Multi-Frame Generation, Super Resolution, and Ray Reconstruction directly into their projects. These additions are expected to bring significant performance and visual gains, especially when paired with UE5.6’s upgraded rendering pipeline and improved CPU/GPU handling.

One of the standout improvements with the Transformer model is its efficiency. As per reports from early testing, it uses up to 20% less VRAM compared to the older CNN model used in earlier DLSS iterations, such as DLSS 2 and 3. That means developers can deliver higher visual fidelity without pushing hardware to its limits.

For developers interested, the DLSS 4 plugin is now available on NVIDIA’s official website.
