DLSS 5 Ghosting, Shimmering, Flickering in Hogwarts Legacy: Fixes

If you’re seeing ghosting, shimmering, or flickering in Hogwarts Legacy with DLSS, the quickest fixes are to update your GPU drivers, switch to a different DLSS preset (Quality instead of Performance), and turn off Ray Tracing or lower its quality. These artifacts are most often caused by the upscaler’s handling of fine details like hair, foliage, and reflective surfaces, and a few settings adjustments can usually eliminate or greatly reduce them.

Background: Why DLSS Causes Visual Artifacts

DLSS (Deep Learning Super Sampling) renders the game at a lower internal resolution and then uses AI to upscale it to your display’s resolution. This process can introduce three common artifacts:

• Ghosting: A trailing or smearing effect behind moving objects, especially noticeable on character capes, hair, or when panning the camera.
• Shimmering: A sparkling or crawling effect on fine details like distant foliage, fences, or stone textures.
• Flickering: Rapid brightness or color changes on surfaces, often on water, puddles, or metallic objects.

Hogwarts Legacy uses Unreal Engine 4, which has known interactions with DLSS that can amplify these issues, particularly when Ray Tracing is enabled. The game’s dense environments—full of moving torches, reflective floors, and intricate architecture—provide many opportunities for the upscaler to make mistakes.

How DLSS Works in Hogwarts Legacy

In Hogwarts Legacy, DLSS is available in the Graphics Options under “Upscale Type.� You can choose DLSS (if you have an NVIDIA RTX GPU), and then select a preset: Quality, Balanced, Performance, or Ultra Performance. These presets determine the internal rendering resolution:

• Quality: Renders at 66.7% of your display resolution (e.g., 1440p on a 4K display). Best image quality, fewest artifacts.
• Balanced: Renders at 58.3% of display resolution.
• Performance: Renders at 50% of display resolution. More artifacts likely.
• Ultra Performance: Renders at 33.3% of display resolution. Only recommended for 8K; heavy artifacts.

The lower the internal resolution, the harder the AI has to work, and the more likely you’ll see ghosting, shimmering, or flickering. The game also has a “DLSS Sharpening� slider, which can make shimmering worse if set too high.

Immediate Fixes to Try Now

If you’re experiencing these artifacts, here are the steps to try, in order of effectiveness:

1. Update your GPU drivers. NVIDIA regularly releases Game Ready drivers that include optimizations for DLSS. Outdated drivers are a common cause of visual glitches.
2. Change the DLSS preset to Quality. If you’re on Performance or Balanced, switch to Quality. The higher internal resolution will reduce artifacts significantly.
3. Disable Ray Tracing. Ray tracing in Hogwarts Legacy is demanding and can cause DLSS to struggle with reflections and shadows. Turn it off or set it to Medium.
4. Lower DLSS Sharpening. Set the sharpening slider to 0 or 50%—anything higher can increase shimmering.
5. Toggle DLSS off and on. Sometimes simply switching to TAA (Temporal Anti-Aliasing) and back to DLSS can clear up a persistent artifact.
6. Restart the game. If you changed settings while the game was running, a restart ensures they apply correctly.

If none of these work, try using DLSS’s “Frame Generation� feature (if your GPU supports it) or switch to AMD FSR (FidelityFX Super Resolution) or Intel XeSS, which may handle certain scenes better.

Common Problem Areas and Specific Fixes

Some locations in Hogwarts Legacy are more prone to artifacts than others. Here’s what to expect and how to handle it:

• Hogwarts Castle interiors: The reflective floors and moving candles can cause ghosting. Lowering Ray Tracing quality or disabling it helps most.
• Hogsmeade village: The cobblestone streets and hanging signs often shimmer. Increase DLSS Quality or disable upscaling entirely.
• Forbidden Forest: Dense foliage and moving leaves cause flickering. Use DLSS Quality and reduce sharpening.
• Character hair and capes: These are the most common ghosting sources. If you notice it during cutscenes, it’s likely DLSS—try TAA instead.

If you’re playing on a laptop or a lower-end GPU, you may need to accept some artifacts as a trade-off for playable frame rates. In that case, prioritize DLSS Quality over other settings.

DLSS vs. FSR vs. XeSS in Hogwarts Legacy

Hogwarts Legacy supports all three major upscaling technologies. If DLSS artifacts are bothering you, compare them:

• DLSS (NVIDIA): Best overall image quality on RTX GPUs, but prone to ghosting in some games.
• FSR (AMD): Works on all GPUs. Often has less ghosting but can have more shimmering on fine details.
• XeSS (Intel): Works on all GPUs but is optimized for Intel Arc. Quality varies by hardware.

Try switching to FSR or XeSS and see if the artifacts are less noticeable. You can do this in the same “Upscale Type� menu. Note that FSR and XeSS don’t require an RTX card, so they’re a good fallback if DLSS is problematic.

Hardware and Driver Considerations

DLSS performance and artifact severity depend on your GPU and driver version. Here’s what to keep in mind:

• RTX 20-series: These cards use the original DLSS (not the newer 3.5 version). Artifacts are more common. Use Quality preset.
• RTX 30-series: Good DLSS support, but still may ghost on fast-moving scenes.
• RTX 40-series: Supports DLSS 3 Frame Generation, which can reduce ghosting by generating entire frames. Use it if available.
• Driver updates: Always install the latest Game Ready driver. NVIDIA has fixed several DLSS issues in Hogwarts Legacy through driver updates.

If you’re using a laptop with a hybrid graphics setup (integrated + discrete GPU), make sure the game is running on the RTX card. Otherwise, DLSS may not work correctly.

Long-Term Solutions and Settings Profile

If you want the best balance of performance and image quality, here’s a recommended settings profile for DLSS users:

• Upscale Type: DLSS
• DLSS Preset: Quality
• DLSS Sharpening: 50%
• Ray Tracing: Off (or Medium if your GPU is powerful)
• Anti-Aliasing: DLSS (it overrides TAA)
• Motion Blur: Off (can mask ghosting but also cause its own artifacts)
• Depth of Field: Off (reduces shimmering on distant objects)

If you still see artifacts, you can try using the “DLSS 3.5� version if available (it includes Ray Reconstruction, which improves reflections). However, this requires a recent driver and an RTX 40-series card.

Frequently Asked Questions

Why does DLSS cause ghosting in Hogwarts Legacy?

Ghosting occurs when the AI upscaler incorrectly blends frames, especially on moving objects with fine details like hair or capes. The lower the internal resolution, the more likely this is. Using DLSS Quality and disabling Ray Tracing reduces it.

Will turning off DLSS fix the shimmering?

Yes, turning off DLSS and using TAA (Temporal Anti-Aliasing) will eliminate DLSS-specific shimmering. However, TAA has its own softness and may reduce performance. You can also try FSR or XeSS as alternatives.

Does DLSS 3.5 fix these issues?

DLSS 3.5 includes Ray Reconstruction, which can improve ray-traced reflections and reduce ghosting in some cases. However, it requires an RTX 40-series GPU and a game that supports it. Hogwarts Legacy does support DLSS 3.5 on compatible hardware.

Is there a mod to fix DLSS artifacts in Hogwarts Legacy?

Yes, there are community mods that replace the DLSS DLL with newer versions or tweak settings. However, mods can be unstable and may not work after game updates. It’s safer to adjust in-game settings first.

Why does flickering happen on water surfaces?

Water reflections are computationally expensive, and DLSS may struggle to upscale them consistently. Disabling Ray Tracing or lowering its quality often fixes water flickering. You can also try a different upscaler.

Does the DLSS preset affect performance a lot?

Yes, Quality preset has the highest internal resolution and thus the lowest performance gain, while Performance gives a bigger boost but more artifacts. If you need more FPS, try Balanced as a compromise.
