NVIDIA DLSS DLL (nvngx_dlss.dll) v2.1.24

Overview

The NVIDIA DLSS DLL is a core runtime component used by games that implement NVIDIA Deep Learning Super Sampling (DLSS). It enables AI-based image upscaling to improve rendering performance while maintaining visual quality, addressing the performance cost of high-resolution rendering in supported games.

Key Features

• AI-based upscaling: Uses trained neural networks to upscale lower-resolution frames to higher resolutions, reducing GPU workload while preserving image detail. This allows higher frame rates at demanding resolutions.
• DLSS version control via DLL: The standalone DLL can be updated or replaced independently of the game, which may improve image quality or performance when newer versions are compatible.
• Real-time processing: Operates during gameplay without requiring user interaction, ensuring seamless performance gains.
• Game engine integration: Works through direct integration with supported game engines, enabling DLSS functionality without separate configuration tools.

Who Should Use This Software?

This component is relevant for PC gamers and technical users running DLSS-supported games on compatible NVIDIA RTX GPUs. It may also be used by developers or advanced users testing different DLSS versions for compatibility or performance evaluation.

Who Should Avoid It?

Users without NVIDIA RTX GPUs will not benefit from this DLL. It is also unsuitable for users unfamiliar with manual file replacement, as incorrect usage may cause game instability or failure to launch.

Real-World Usage Notes

The DLL itself does not run as a standalone application and has no user interface. Its effect is only observable within DLSS-enabled games. Performance and visual results depend on the specific game implementation and driver compatibility.

Compatibility & Requirements

• Supported operating systems: Windows
• Hardware requirement: NVIDIA RTX-series GPUs
• Deployment: Game-level DLL file (not installable or portable as a standalone program)
• Integration: Loaded by DLSS-supported games and dependent on compatible NVIDIA drivers

Limitations

• Functionality is entirely dependent on game support for DLSS
• Visual results may vary between titles and versions
• Not backward-compatible with non-DLSS or non-RTX systems

Safety & Privacy

The DLL does not operate independently in the background and does not collect user data. It functions only when loaded by a supported game and relies on existing NVIDIA driver permissions.

Summary

NVIDIA DLSS DLL v2.1.24 is a functional runtime component that enables AI-based upscaling in DLSS-supported games. It is most useful for RTX GPU users seeking improved performance in compatible titles, provided it is used with proper understanding of game and driver compatibility.
