Leaked DLSS 5 Library Found in NBA 2K27, Modders Get it Running in Control

DLSS 5 Library Discovered in NBA 2K27

A new Nvidia library, nvngx_dlssnr.dll, identified as Nvidia DLSSNR and linked to DLSS 5 neural rendering technology, has been discovered within the early access version of NBA 2K27. This finding suggests that NBA 2K27 may be one of the first titles to officially support Nvidia's upcoming DLSS 5 technology.

Modders Implement DLSS 5 in Control

Developers from RenoDX, a modding toolset community, successfully integrated the leaked DLSS 5 library into the game Control. They applied the technology to character models within the game, demonstrating its operational capabilities. This early implementation allows for initial observation of DLSS 5's features, including adjustable parameters for style, intensity, tone, and structure strength.

Early Performance on Blackwell GPUs

According to reports from the RenoDX Discord server, DLSS 5 currently functions only on Blackwell GPUs. Initial testing on an RTX 5070 Ti at 4K resolution showed a performance reduction from 71 FPS to 35 FPS when DLSS 5 was enabled. However, specific DLSS 5 settings and internal rendering resolutions used for this test were not detailed, indicating that this performance data may not be fully representative of the final release.

Context and Future Expectations

Nvidia first introduced DLSS 5 in March and announced its official launch for this fall. While the current implementation is an early, modder-injected version, the performance impact is not entirely unexpected. Nvidia previously demonstrated DLSS 5 on two RTX 5090s, and later presented a distilled, more efficient version at SIGGRAPH 2026 capable of running on a single GPU. Further optimizations are anticipated before the official launch, but DLSS 5 is still expected to be a demanding technology in practice.
