Error Message None Visual Glitch Severe Lumen ghosting and temporal artifacts:

  • Details: Since the v0.8.0 “Freelancer” update, I have encountered significant visual regressions that affect gameplay immersion:
  • Lumen Artifacts: When Lumen Global Illumination is enabled, moving the character creates a heavy “ghosting” or “smearing” trail. This is especially noticeable in indoor environments (like the kitchen/bedroom) and even within the Character Studio (CAP).
  • Reflection Issues: I noticed that when Global Screen Illumination is set to Medium, the character’s reflection completely disappears from mirrors. The mirrors only reflect the environment, leaving the character invisible.
  • Upscaling & Blur: The game seems to prioritize TAA over TSR in certain quality modes, which exacerbates the ghosting effect on my RTX 3050.
  • Performance vs. Quality: Even though the frame rate is stable, these temporal artifacts make the game look “muddy” during movement. These issues were not as prominent in earlier builds of the game.

Steps to Reproduce:

Enter any indoor lot (e.g., Dowon Villa).

Ensure Lumen Global Illumination is turned ON.

Move the character laterally

in front of a dark or neutral background.

Set GI to Medium and look into a mirror to observe the missing character reflection.

Hello,

After the 5.6 migration I have also noticed this in Create A Zoi, it is pretty severe even with Ultra. The other issues I am not sure I have experienced them but let me try to help a bit, I am very far from an expert though!

Have you tried:

  • disabling NVIDIA Image Scaling / sharpening if enabled in NVIDIA Control Panel

  • forcing TSR OFF if possible and using native TAA or DLSS instead

  • increasing the Windows shader cache size in NVIDIA Control Panel to Unlimited

  • deleting:

    • %localappdata%\NVIDIA\DXCache

    • %localappdata%\D3DSCache

    • %localappdata%\inZOI\Saved\DerivedDataCache

This really smells like broken temporal history/shader cache behavior after the update. Another thing is
on 4GB VRAM cards, Medium GI may actually be silently disabling certain reflection passes to stay within memory limits, which would explain:

“environment reflects but character disappears”

That is actually a known behavior in some UE5 implementations when VRAM gets tight. it’s probably tied to UE5.6 rendering changes + aggressive VRAM management after the update, not just user settings alone. I would encourage you to post a bug report if you don’t manage to fix it, if it hasn’t been already posted
