DLSS 3.5 DLL Download & Installation Guide

DLSS 3.5 Overview

DLSS 3.5 introduces Ray Reconstruction (RR), a groundbreaking AI model that enhances ray-traced image quality. Instead of relying on hand-tuned denoisers, Ray Reconstruction uses an AI network trained on 5X more data than DLSS 3 to generate higher quality pixels in between sampled rays. This results in sharper reflections, more accurate lighting, and better performance in heavy RT scenarios.

Release Information

DLSS 3.5 focuses on maximizing the visual fidelity of Ray Tracing. While Super Resolution and Frame Gen improve performance, Ray Reconstruction improves the quality of the lighting itself. It works on all RTX GPUs (20 series and up), unlike Frame Generation which is limited to 40 series.

DLSS 3.5 Changelog

  • Ray Reconstruction: AI-powered denoiser for superior RT quality.
  • Trained on 5X more data than DLSS 3.1.
  • Reduced "smearing" artifacts in fast-moving RT reflections.
  • Improved recognition of lighting effects/shadows.

Games with Ray Reconstruction Support

To fully benefit from DLSS 3.5 features, games must explicitly support Ray Reconstruction:

How to Install DLSS 3.5 DLL

  1. Download the nvngx_dlss.dll file (version 3.5.x).
  2. Locate the game's installation folder.
  3. Open the game's "bin" or "Win64" directory.
  4. Backup your original file. Rename it to nvngx_dlss.dll.bak.

DLSS 3.5 Yes Very High Heavy Ray Tracing Games

Common Issues

  • Can't find Ray Reconstruction option? Ensure you have the latest Game Ready Driver and an RTX GPU.
  • DLSS option greyed out? Check Windows "Hardware-accelerated GPU scheduling" settings.

Frequently Asked Questions

Does DLSS 3.5 work on RTX 20/30 cards?

Yes! Ray Reconstruction and Super Resolution (the upscaling part) work on ALL RTX GPUs. Only Frame Generation remains exclusive to RTX 40 series.

Can I put DLSS 3.5 in older games?

Yes, you can use the DLSS 3.5 DLL in older DLSS 2.0 games. You won't get Ray Reconstruction features, but you will benefit from the updated AI model training for better general image quality.
