I’m glad at least most of the flickering is gone now
It might be worth a try to clear the shaders / PSO cache too. Here’s the exact part from the devs’ official guide:
3. Manually Clear PSO Cache (Shader Cache)
Crashes may occur if the graphic shader cache files are corrupted.
CAUTION : Ensure the game is completely shut down before proceeding with the steps below.
A. Clear Shader Cache In-Game (Recommended)
If a pop-up window appears when you launch the game asking, “Do you want to delete the PSO Cache?”, click ‘Yes ’ to clear the cache. The game will automatically restart after the cache is cleared. Please check if the issue is resolved afterward.
B. Manually Remove Shader Cache Folders
If the in-game pop-up does not appear or does not resolve the issue, you can manually remove the cache by following the paths below.
Open File Explorer : Press Windows Key + E.
Navigate to Path : Copy and paste the paths below into the File Explorer address bar and press Enter.
Cache File Paths :
[AMD]
C:\Users\username\AppData\Local\AMD\DxCacheC:\Users\username\AppData\LocalLow\AMD\DxCacheC:\Users\username\AppData\Local\D3DSCacheC:\Users\username\AppData\Local\AMD\DxcCache
[NVIDIA]
C:\Users\username\AppData\Local\NVIDIA\DXCacheC:\Users\username\AppData\LocalLow\NVIDIA\PerDriverVersion\DXCacheC:\Users\username\AppData\LocalLow\NVIDIA\DXCacheC:\Users\username\AppData\Local\D3DSCache
[Intel]
C:\Users\username\AppData\LocalLow\Intel\ShaderCacheC:\Users\username\AppData\Local\D3DSCache
Locate Cache Files/Folders : In each path, look for folders or files named ShaderCache or PSO Cache, or files within those folders.
Delete Folders/Files : Right-click the corresponding folder and files and select ‘Delete’.
Restart Game : Relaunch the game to check if the crash is resolved.Important Note :
Manually deleting the shader cache will also remove cached data for other games that share these folders.
As a result, the next time you launch other games, the loading time may be longer than usual as the cache is rebuilt.
Some of the flickering might also happen due to the game’s Unreal Engine 5. It is known for various lighting bugs unfortunately.
