How to Fix Wuchang Crashes & Stuttering on PC (Shader Compilation, VRAM Errors)

on

Wuchang: Fallen Feathers might offer a beautifully haunting journey through mythic China, but for many PC players, that journey keeps crashing—literally. From shader compilation errors to "out of VRAM" crashes, poor performance has haunted early adopters.

The good news? With Patch 1.3 and a few manual tweaks, you can vastly improve your frame rate and stability. Below, we’ll break down exactly what’s causing the issues, how to fix them, and what the devs are doing to help.

Let’s reclaim your frames and banish those stutters.

⚙️ Quick Fix Summary

  • ✅ Update to Patch 1.3 – adds VRAM optimization and fixes crashes.

  • ✅ Clear shader cache (NVIDIA & AMD instructions below).

  • ✅ Tweak your Engine.ini for smoother performance.

  • ✅ Lower texture quality on GPUs under 8 GB VRAM.

  • ✅ Disable Global Illumination for stutter-free exploration.

  • ✅ Cap DLSS to 99% instead of 100% to avoid DLAA glitches.

How to Fix Wuchang Crashes & Stuttering on PC
1. Update to Patch 1.3 (Performance Hotfix)

The July emergency patch improves VRAM handling, texture streaming, and startup crashes.

Key fixes include:

  • Reduced memory usage on GPUs ≤ 8 GB VRAM at all texture settings.

  • Improved shader preload & startup stutter during finisher animations.

  • Startup crash fix that occurred right after the developer logo.

2. Clear Your Shader Cache (NVIDIA/AMD)

Stuttering during traversal or cutscenes? Your shader cache is likely corrupted.

For NVIDIA users:

  • Open NVIDIA Control Panel

  • Go to Manage 3D Settings > Shader Cache Size

  • Set to Unlimited (or Disable, restart, then re-enable)

  • Optional: Delete cached shaders at:
    C:\Users\[Name]\AppData\Local\NVIDIA\DXCache
    C:\Users\[Name]\AppData\Local\NVIDIA\GLCache

For AMD users:

  • Open AMD Software: Adrenalin Edition

  • Go to Settings > Graphics > Advanced

  • Click Reset Shader Cache

3. Modify Engine.ini for Extra Stability

Custom tweaks to Engine.ini (UE5 config file) can improve stuttering and GPU consistency.

Do this:

  1. Go to:
    C:\Users\[YourName]\AppData\Local\Wuchang\Saved\Config\WindowsNoEditor\Engine.ini

  2. Add the following lines at the end:

[SystemSettings]
r.TextureStreaming=0
r.OneFrameThreadLag=1
r.Streaming.FullyLoadUsedTextures=1
r.Streaming.HLODStrategy=2

4. Lower Texture Settings for Low VRAM GPUs

If your GPU has 8 GB VRAM or less, you must lower texture quality to avoid out-of-memory crashes. Even with Patch 1.3, this remains a key trigger for shader-related CTDs.

  • Go to Settings > Graphics > Texture Quality → Low or Medium

  • Restart the game after changing this!

5. Avoid DLAA (DLSS at 100%) – Set DLSS to 99%

Many players using DLSS noticed crashes or hitching when it’s set to 100% (DLAA).

✅ Fix:

  • Open Graphics Settings → DLSS → Set Render Scale to 99%

  • Don’t use DLAA or "Native" with DLSS on mid-range GPUs.

6. Disable Global Illumination (Optional Boost)

In your Engine.ini, you can also disable GI entirely if performance is still bad:

r.DynamicGlobalIlluminationMethod=0
r.Lumen.Reflections=0
r.Lumen.GlobalIllumination=0

This sacrifices visual lighting fidelity but provides up to +30 FPS on low-end GPUs.

πŸ§ͺ Final Thoughts: The Game Is Recoverable

While Wuchang: Fallen Feathers launched with some serious PC hurdles, performance is improving quickly—and the community is stepping up to help. Most crash and stutter issues come down to shader compilation handling and VRAM management, both of which now have reliable workarounds.

If you’re still stuck, reach out or follow mod threads—updates and engine fixes are evolving fast.
