A DLSS 5 DLL has leaked through an early NBA 2K27 build, revealing NVIDIA's next-gen upscaler ahead of its official launch. The file, digitally signed by NVIDIA on August 11, is version 310.8.0—higher than any known DLSS release. It contains a massive 158.2 MB payload, with 140.9 MB dedicated to trained model weights, totaling roughly 148 million parameters in FP8 format.

This suggests DLSS 5 heavily relies on neural networks for rendering, likely integrating features like ray reconstruction and frame generation. The DLL cannot be used in games yet, as NBA 2K27 exposes no setting to enable it, and other titles lack the required code to load it. The leak hints at imminent official announcements, but NVIDIA has not commented.

Analysts believe the file is a development build, not the final release version, given its changelist number and unoptimized size. Despite the excitement, gamers should wait for proper integration and driver support before expecting DLSS 5 benefits.
