Fix Blurry or Ghosted Images After Enabling DLSS

If you’ve turned on DLSS and suddenly your game looks soft, smeared, or has visible ghosting trails behind moving objects, you’re not alone. This guide walks you through the most effective fixes, from simple settings toggles to driver-level changes, so you can keep the performance boost without the visual artifacts.

What You’ll Need

• Access to your game’s video/graphics settings menu
• NVIDIA GeForce Experience or the NVIDIA Control Panel (for driver updates and global settings)
• Your monitor’s native resolution (check the display settings in Windows)
• Patience – some fixes require restarting the game or PC

Step-by-Step

1. Update your graphics drivers. Outdated drivers are a common cause of DLSS artifacts. Open GeForce Experience, go to the Drivers tab, and click “Check for Updates.� If an update is available, download and install it. Restart your PC after the update.
2. Set the game resolution to your monitor’s native resolution. If your in-game resolution is lower than your monitor’s native resolution, DLSS will upscale from an even lower base, causing blur. Go to the game’s display settings and make sure the resolution matches your monitor’s native resolution (e.g., 1920×1080 for a 1080p monitor).
3. Choose a higher DLSS quality preset. DLSS presets (Quality, Balanced, Performance, Ultra Performance) trade internal resolution for performance. “Quality� gives the sharpest image, while “Ultra Performance� is the blurriest. Switch to “Quality� or “Balanced� and see if the blur/ghosting improves.
4. Disable sharpening or adjust it. Some games apply a sharpening filter on top of DLSS. If it’s set too high, it can cause haloing and ghosting. Find the sharpening slider (often under DLSS settings or in the game’s graphics options) and lower it to 30-50% or turn it off entirely.
5. Turn off motion blur and depth of field. These post-processing effects can enhance the perception of ghosting. Disable them in the game’s video settings and test again.
6. Check for in-game DLSS version updates. Some games let you update DLSS files manually. If you’re comfortable, download the latest DLSS DLL from a trusted source (like TechPowerUp) and replace the one in the game’s folder. This can fix known ghosting issues in older versions.
7. Toggle DLSS off and on. Sometimes the game’s renderer gets into a bad state. Turn DLSS off, apply, then turn it back on to the desired preset. This can clear temporary artifacts.
8. Verify game files. If the issue persists, corrupted game files may be the culprit. In Steam, right-click the game, select Properties → Local Files → Verify Integrity of Game Files. On other platforms, use the equivalent option.
9. Reset the game’s configuration file. If all else fails, back up and delete the game’s config file (usually in Documents or %AppData%). The game will recreate it with default settings. Then re-apply your desired DLSS settings.

Common Mistakes

• Using DLSS at a lower resolution than native. DLSS is designed to upscale from a lower internal resolution, but if the output resolution is lower than your monitor’s native, you’re essentially upscaling twice, causing blur.
• Setting sharpening too high. Over-sharpening can create a “crunchyâ€� look and exaggerate ghosting.
• Ignoring driver updates. DLSS improvements are often tied to driver releases. Skipping updates means missing fixes.
• Using “Ultra Performanceâ€� on a 1080p monitor. This preset is meant for 4K. On lower resolutions, it produces a very soft image.

Tips

• If you have an NVIDIA GPU that supports DLSS, you can also try DLSS 3.5 (if the game supports it) which includes Ray Reconstruction – it often improves image quality and reduces ghosting.
• Use the in-game benchmark or a known scene to test changes. Move the camera quickly to see ghosting more clearly.
• Keep your Windows display scaling at 100% (or the recommended value) to avoid additional scaling blur.
• If you’re using a custom resolution or HDR, make sure those are set correctly – mismatched settings can interfere with DLSS.

Troubleshooting

If the steps above don’t resolve the issue, try the following:

• Disable G-Sync/FreeSync temporarily. In some rare cases, adaptive sync can conflict with DLSS. Turn it off in the NVIDIA Control Panel and test.
• Check if the issue is specific to one game. If other DLSS games look fine, the problem is likely in that game’s settings or files.
• Run the game in fullscreen mode. Borderless windowed mode can introduce additional scaling layers that blur the image.
• Reinstall the game as a last resort. This ensures a clean slate, but only after backing up your saves.
• Consider that the game’s DLSS implementation may be broken. In that case, wait for a patch or use a mod if available.

Frequently Asked Questions

Why does DLSS cause ghosting?

Ghosting occurs because DLSS uses temporal information (previous frames) to reconstruct the image. When there’s fast motion or a large contrast change, the algorithm can leave trails behind objects. This is more noticeable in certain games or with older DLSS versions.

Does DLSS reduce image quality permanently?

No. DLSS is designed to look close to native resolution, and in many cases, it can look better thanks to its AI-based reconstruction. If it looks bad, it’s usually a settings issue or a game-specific bug.

Can I use DLSS with a non-NVIDIA GPU?

No, DLSS requires NVIDIA RTX GPUs. However, AMD’s FSR and Intel’s XeSS are alternatives that work on a wider range of hardware, though they may not have the same image quality.

Does DLSS work on all games?

No, DLSS must be implemented by the game developer. Many modern titles support it, but not all.

Will DLSS improve my FPS?

Yes, DLSS can significantly boost FPS by rendering at a lower internal resolution and upscaling. The performance gain depends on the preset and your hardware.

Is DLSS 3.5 better than DLSS 2?

DLSS 3.5 includes Ray Reconstruction, which improves ray-traced effects and can reduce ghosting. However, it requires a compatible GPU and game support.
