Nvidia has released its highly-praised DLSS technology on to the Unreal Engine marketplace as a free plugin. This essentially means that games that run on Unreal Engine 4.26 and onwards don’t really need Nvidia’s approval to use include DLSS. Those interested in taking it out for a spin can find a link for it on the Unreal Engine Marketplace.
DLSS, which stands for Deep Learning Super Sampling, uses Tensor Core AI processors present on Nvidia’s GeForce RTX graphics cards to boost frame rate without the losing out on much in terms of quality. The Unreal Engine plugin’s implementation allows full use of DLSS, leading to higher frame rates in games, even with RTX cranked up to the max.
How it works is pretty cool; the Tensor Core AI processors are used as a neural network to produce image quality that’s comparable, and even some times better, than what you would get with DLSS off. With the tech, only a fraction of the pixels need to be rendered, taking a lot of processing load off GPU.
With the plugin, DLSS is integrated fully into the Unreal Editor UI. For developers, it also includes a Blueprint library for integration of DLSS, and supports packaged projects as well as Editor-focused workflows.
The only real down side to all of this is that DLSS is an Nvidia-specific technology, which means that systems running on AMD’s graphics cards aren’t able to use it. This is because DLSS requires the use of the Tensor Core AI processors, which are only present on RTX 2000 and 3000 series graphics cards.
