A preliminary edition of NVIDIA’s new graphics technology, which escaped to the internet in recent days, already works on previous generation video cards. The technical tweak, conducted by enthusiasts since late August 2026, exposed the internal mechanics of the manufacturer’s neural rendering library, but also revealed a sharp decline in frame rate during initial evaluations. This scenario raises doubts about how the company will handle optimization for older hardware, recalling the brand’s history of restricting software innovations to the most recent lines to boost sales of new equipment.
Where unreleased NVIDIA files were located by the community
The central component responsible for Neural Rendering, which is still awaiting a formal announcement from the manufacturer, ended up exposed within the files of the test version of the sports title NBA 2K27. Named in the system as nvngx_dlssnr.dll, the digital document quickly became the target of investigation by independent programmers.
The RenoDX group, famous for creating advanced modifications to computer games, managed to integrate this file to run in the acclaimed game Control. Soon after, this same testing structure was successfully applied to more than ten other games, proving that the tool has a highly adaptable basis.
The technical process to release the tool on the Ada Lovelace architecture
In the format in which it was leaked, the graphics resource was blocked to work exclusively on the RTX 50 line, which represents the brand’s next family of visual processors. This lock existed because fragments of the code contained CUDA instructions programmed specifically for the Blackwell architecture, preventing recognition by previous chips.
The programmer known as Uncle Burrito, who gained notoriety for his projects involving the RTX Remix platform, mapped out exactly which instructions caused conflict with the Ada Lovelace architecture. By exchanging these code blocks for compatible equivalents, he unlocked the use of Neural Rendering on last generation video cards, including high-cost hardware such as the GeForce RTX 4090 and RTX 4080.
Drastic drop in frame rate worries current hardware users
Even with the success in breaking the block, the performance delivered by the test edition on the RTX 40 family suffered a severe blow. Evaluations conducted using a powerful GeForce RTX 4090 revealed that the computational cost of the new technique drops visual fluidity alarmingly.
In one of the scenarios analyzed, the frame count dropped from 135 to just 82 as soon as the new feature was activated. This drop reflects a loss of approximately 39% in processing capacity, raising an alert for those who invested heavily in the current generation and expected longevity.
- In the evaluation with the GeForce RTX 4090: fluidity dropped from 135 to 82 frames per second, marking a 39% loss.
- In previous measurements using a GeForce RTX 5070 in the Cyberpunk 2077 title: performance dropped from 138 to 68 frames.
- During tests with the GeForce RTX 5070 Ti in the game Control: the negative impact consumed practically half of the original performance.
It is essential to note that these poor metrics are not exclusive to older hardware, as similar drops appeared in leaked tests of the RTX 50 line itself, including the entry-level model RTX 5060. Although NVIDIA confirmed that its internal demonstrations ran on machines equipped with two RTX 5090 simultaneously, public experiments prove that the code base already communicates with several Blackwell architecture chips.
What to expect from the official schedule and future software updates
The encouragement for PC gamers is that the current code represents just a draft and is far from the product that will hit the market. The frame rates recorded at this time do not serve as a verdict, as the manufacturer’s engineering team still has months of work ahead to refine the processing.
The company plans to officially release the new feature only in the last months of the year. While this doesn’t happen, the exposed files and modifications from the RenoDX group provide enthusiasts with an open laboratory on how the tool works. This early access ensures that the community understands the mechanics of rendering long before its debut, generating data that can even influence fixes. Ultimately, the real viability of this technology on GeForce RTX 40 cards will depend exclusively on the effort that NVIDIA will dedicate to optimizing the old drivers.
