NVIDIA unveils DLSS 4 plugin for Unreal Engine 5.6: next-gen AI upscaling for game developers

NVIDIA has just unleashed DLSS 4 upscaling support into Unreal Engine 5.6, allowing game developers to add the latest AI upscaling technology into UE5.6-based titles.

NVIDIA launched its new GeForce RTX 50 series "Blackwell" GPUs earlier this year, which support DLSS 4 upscaling, but before game developers can add DLSS 4 into their games, the company must make an official plugin... and today is that day for Epic Games' Unreal Engine 5.6.

Unreal Engine 5 already supports NVIDIA DLSS 4 upscaling for various versions of the engine in the 5.0 series, but Unreal Engine 5.5 and 5.6 have just received their own DLSS 4 plugin, which has been made available on NVIDIA's website.

Unreal Engine 5.6 launched last month with performance improvements compared to previous versions, with huge CPU and GPU performance gains, as well as the Transformer model upscaling and features like Frame Generation, Multi-Frame Generation, Ray Reconstruction, and Super Resolution, the Unreal Engine developers can inject these features into their games made in Unreal Engine 5.6.

NVIDIA's Transformer model broke out of beta just a few days ago now, with the new Transformer model using 20% less VRAM. There are other advantages with the new Transformer model over the CNN model that is used in DLSS 1, DLSS 2, DLSS 3, and DLSS 3.5, and now that the Transformer model is available in Unreal Engine 5.6, games can be optimized even further, allowing for better-quality graphics with more performance.

NVIDIA explains on its website: "DLSS 4 is in Unreal Engine through our official DLSS Unreal Engine plugin. The plugin provides access to Multi Frame Generation, Frame Generation, Ray Reconstruction, Super Resolution, DLAA, Reflex Low Latency, and NVIDIA Image Scaling".
