DLSS 5 Leaked Out of NBA 2K27, and Modders Already Have It Running in Control

A basketball game is a strange place to find Nvidia's next graphics technology, and yet here we are. NBA 2K27 went into early access this week carrying a file called nvngx_dlssnr.dll, short for DLSS Neural Rendering. Developer Renan Maniero spotted it. Within hours, modders had pulled it out and forced it into games it was never meant to touch.

DLSS 5 has not launched. Nvidia announced it in March and said it would arrive this fall, and a library buried in a basketball build is not a release. What people are running today is an unfinished piece of software that escaped early, injected into titles with no official support for it, at settings nobody outside Nvidia fully understands yet.

The number everyone is passing around

A RenoDX modder got it working in Control on an RTX 5070 Ti and measured 71 FPS at 4K with DLSS 5 off, then 35 FPS with it on. Cut in half. That figure is bouncing around every forum today, usually with the word "unplayable" attached to it.

The developer never said which DLSS 5 settings were active, or what internal render resolution the test ran at. Both of those change the answer enormously. A leaked renderer hacked into a 2019 game tells you it runs. It does not tell you what it costs.

What DLSS 5 is supposed to do

The DLSS you know renders fewer pixels and reconstructs the rest. Neural rendering is a different job. It takes the frame's color and motion data and re-lights it, going after the things real-time graphics have always faked badly: light scattering under skin, light passing through hair, materials that behave the way materials do. Jensen Huang called it "the GPT moment for graphics" back in March, which tells you how Nvidia would like this received.

Nvidia has also been busy making it cheaper to run. At SIGGRAPH 2026 the company showed a distilled, more efficient version of the model running on a single GPU. Worth keeping in mind before you take an August leak's frame rate as the shipping cost.

Everybody looks a little wrong

Performance is the smaller complaint right now. The bigger one is faces. Modders ran the leaked library over Control, Skyrim and Final Fantasy VII Rebirth, and it has not been kind to the cast. Jesse Faden came out looking decades older. Skyrim NPCs picked up a glassy, dead-behind-the-eyes stare. Cloud came out looking like somebody else.

Some of it does look good. Comparison shots from Control show better shadows and light transmission without wrecking the game's art direction, which is the same worry Nvidia spent SIGGRAPH answering. But a model that was never tuned for Skyrim, running through a hack, on characters no artist signed off on, is going to produce exactly this kind of mess.

Wait for the real one

If you own an RTX 50 card and you want to try this now, you can, and plenty of people are. You would be judging a technology by a build that fell out of a basketball game. The version that ships this fall will be different software with different numbers, and screenshots from this week are a bad basis for deciding whether you want it.

The leak does confirm one thing. DLSS 5 is far enough along that it is already being packed into games heading out the door. Fall starts in a few weeks.
