Modders Get DLSS 5 Running on RTX 40 GPUs

NVIDIA DLSS 5 is a proprietary deep learning super sampling technology developed by NVIDIA, and it is designed to be exclusive to the company's Blackwell GPU architecture. The technology was announced at GTC 2026, and it introduces a Neural Rendering engine that is intended to improve performance and image quality in supported video games. Modders have now circumvented this hardware restriction, successfully enabling DLSS 5 to run on the older RTX 40 Series graphics cards, which are based on the Ada Lovelace architecture.

This unofficial implementation was achieved by a modder known as Uncle Burrito, who built upon the initial work of the RenoDX community. The breakthrough allows owners of RTX 40 Series GPUs to test the new technology, although it comes with a significant performance cost. The official release of DLSS 5 is expected later this year, with NBA 2K27 currently being the only title officially confirmed to use the technology.

Key Facts

This section provides a summary of the verified technical and factual details regarding the unofficial DLSS 5 implementation on RTX 40 Series GPUs, as reported in the source material.

How Did Modders Get DLSS 5 Working on RTX 40 Series GPUs?

Modders enabled DLSS 5 on RTX 40 Series GPUs by identifying and replacing the Blackwell-only CUDA binaries that were incompatible with the older Ada Lovelace architecture. The modder Uncle Burrito swapped these specific binary versions with compatible ones, allowing the DLSS 5 Neural Rendering engine to function on the RTX 40 Series hardware.

This development follows the discovery of the DLSS 5 DLL file within the game NBA 2K27 by members of the RenoDX community. Uncle Burrito then took this initial implementation a step further by adapting it for the previous generation of graphics cards. The modification was demonstrated using an RTX 4090, and the modder also confirmed that the implementation was successfully tested on an RTX 4080.

The unofficial DLSS 5 patch for RTX 40 Series GPUs was achieved by replacing Blackwell-only CUDA binaries with versions compatible with the Ada Lovelace architecture.

What Is the Performance Impact of DLSS 5 on RTX 40 Series GPUs?

Enabling the DLSS 5 Neural Rendering engine on an RTX 40 Series GPU results in a significant performance drop. In a test using the game Control at 4K resolution, the average frame rate fell from 135 fps to 82 fps when the Neural Rendering engine was active, representing a decrease of 53 frames per second.

This performance hit is unsurprising, as the technology is not natively optimized for the older architecture. While the mod successfully bypasses the software restrictions, the hardware limitations of the RTX 40 Series are evident. The modder, Uncle Burrito, also expressed uncertainty about whether the technology could be made to work on the even older RTX 20 and 30 Series cards.

In a 4K test using Control, the average frame rate on an RTX 4090 dropped from 135 fps to 82 fps when the DLSS 5 Neural Rendering engine was active.

Who Is This For?

This unofficial DLSS 5 implementation is for owners of RTX 40 Series graphics cards who want to experiment with NVIDIA's latest rendering technology before its official release. It is a technical mod for enthusiasts and early adopters who are willing to accept a significant performance penalty to test the new Neural Rendering features.

It is important to note that this is not an official NVIDIA release, and the company is not expected to make the feature available for older generation architectures. The mod is a proof-of-concept from the modding community, demonstrating the potential to bypass hardware restrictions, but it is not a solution for users seeking optimal performance on RTX 40 Series hardware.

This mod is intended for RTX 40 Series owners who are technical enthusiasts and wish to test the DLSS 5 Neural Rendering engine, despite a significant performance cost.

Common Questions

Will NVIDIA officially support DLSS 5 on RTX 40 Series GPUs?

No, NVIDIA's DLSS 5 and its Neural Rendering engine are intended to be exclusive to Blackwell GPUs. The source material states that NVIDIA is not expected to make the feature officially available for older generation architectures.

Which games are confirmed to use DLSS 5?

Currently, NBA 2K27 is the only title officially confirmed to be using the technology. The DLSS 5 DLL file was discovered in this game, which led to the initial unofficial implementation by the RenoDX community.

Can DLSS 5 be made to work on RTX 20 and 30 Series cards?

It is uncertain. The modder Uncle Burrito noted that they are not sure if they can get DLSS 5 working on RTX 20 and 30 series cards. The source material also expresses doubt about the feasibility of such an implementation.
