NVIDIA has officially launched the DLSS 4 plugin for Unreal Engine versions 5.5 and 5.6, empowering game developers to utilize advanced AI technology to boost game performance on all RTX GPUs.

With the introduction of DLSS 4, developers can now integrate features like enhanced image resolution, increased frame generation, multi-frame handling, and improved ray tracing capabilities.

Unreal Engine 5.6, released in June 2025, brings significant CPU and GPU performance enhancements, alongside new features such as Frame Generation, Multi-Frame Generation, Ray Reconstruction, and Super Resolution.

This plugin is compatible with Unreal Engine versions ranging from 5.2 to 5.6, equipping developers with tools to significantly enhance their games.

The DLSS 4 plugin allows for further optimization of games, leveraging the improved performance capabilities introduced in Unreal Engine 5.6.

A key advancement in DLSS 4 is NVIDIA's new Transformer model, which has successfully exited beta testing and reduces VRAM usage by 20% compared to the previous CNN model used in DLSS 3.5.

This reduction in VRAM usage offers better optimization for visual fidelity without straining system resources, making it a significant upgrade for developers.

Additionally, Unreal Engine 5.6 features various updates and tools, encouraging developers to explore mobile development tools, MetaHuman Creator, new game templates, animation features, and motion design tools.
