If you play modern PC games, you may have come across an error about nvngx_dlss.dll. This file is part of NVIDIA’s DLSS (Deep Learning Super Sampling) technology, which boosts game performance by using AI to render smoother graphics.
When nvngx_dlss.dll goes missing, gets corrupted, or fails to load, games like Cyberpunk 2077, Fortnite, or Call of Duty may crash or refuse to launch. I remember first seeing this error while trying to run FiveM with ray tracing enabled—frustrating, but thankfully fixable.
The good news? These issues usually come down to driver problems, outdated game files, or a missing DLL, and you can solve them step by step.
Tools You'll Need
Before we jump into fixes, here are the safe tools and resources you may need:
Driver Talent – Recommended for automatic driver/DLL repair.
A stable internet connection.
Your game platform (Steam, Epic Games, or Rockstar) to verify files.
Windows built-in tools (Command Prompt, System File Checker).
Tip: You don’t need all of these for every fix. Start with the simple ones and only move to advanced methods if necessary.

Advanced Manual Solutions
If you prefer manual troubleshooting, here are reliable step-by-step methods.
1. Update Your NVIDIA GPU Drivers
Old or corrupted graphics drivers are the main reason behind nvngx_dlss.dll errors.
Steps:
Right-click the Start Menu → select Device Manager.
Expand Display Adapters.
Right-click your NVIDIA card → choose Update Driver.
Select Search automatically for drivers.
Alternatively, download the latest drivers directly from the NVIDIA website
Pros: Official and safe.
Cons: Can be confusing if you pick the wrong driver version.
2. Verify Game Files
Corrupted or missing game files often trigger nvngx_dlss.dll errors.
Steps (Steam):
Open Steam → go to Library.
Right-click the game → choose Properties.
Under Installed Files, click Verify integrity of game files.
On Epic Games Launcher:
Go to Library → click the three dots next to the game → select Verify.
Pros: Fixes game-specific DLL problems automatically.
Cons: Takes time depending on game size.
3. Reinstall DirectX and Visual C++ Redistributables
Sometimes, DLL issues come from missing system components.
Steps:
Download the latest DirectX Runtime from Microsoft.
Install all Visual C++ Redistributable Packages (2010–2022).
Pros: Fixes a wide range of DLL/game errors.
Cons: Requires multiple downloads.
4. Manually Replace nvngx_dlss.dll (Not Recommended)
Some guides suggest downloading nvngx_dlss.dll from random websites. I don’t recommend this—it’s unsafe and may expose your PC to malware.
If you must, only copy the DLL from a trusted source:
Reinstall the game (fresh DLL files are included).
Or copy the DLL from another PC with the same GPU setup.
Pros: Direct fix if only one DLL is missing.
Cons: Risky, not beginner-friendly.
What to Do If Nothing Works
If none of the above solves your nvngx_dlss.dll issue:
Reinstall the game completely.
Roll back recent Windows updates (if the error started after an update).
As a last resort, reinstall Windows to reset all system files.
In my experience, Driver Talent plus updating GPU drivers fixes 90% of DLL errors without needing a full reinstall.
