If the game loads unusually slowly or if some scenes are choppy, the culprit may be the shader cache* generated by the GPU driver.
Clearing the cache may resolve this issue. If not, try disabling the shader cache.

*The shader cache is operated by the GPU driver, so it cannot be controlled from within programs, such as Hajimari no Kiseki.
You will need to clear and/or configure the following settings specific to your hardware.

■NVIDIA GPUs (GeForce, etc.)
The shader cache is stored in the following folder:
C:\ProgramData\NVIDIA Corporation\NV_Cache
Please delete the files in this folder.

To disable the shader cache, right-click on the Windows desktop, open the NVIDIA Control Panel, and under Manage 3D Settings, turn Shader Cache to Off.

■AMD GPUs (Radeon, etc.)
You can delete or disable the shader cache by right-clicking on the Windows desktop and selecting AMD Radeon Software.
To delete the shader cache, refer to Reset Shader Cache on the following page:

To disable the shader cache, refer to Shader Cache on the following page:

■Intel GPUs (HD Graphics, Iris, etc.)
The shader cache is stored in the following folder:
C:\ProgramData\Intel\ShaderCache
Please delete the files in this folder.

If you cannot see the contents of the ProgramData folder, check View -> Hidden Files in the Explorer menu.

■DirectX Shader Cache
In addition to deleting the GPU shader cache above, please also try deleting the DirectX shader cache.
Right-click [Local Disk (C:)] in Explorer and select [Properties].
Click [Disk Cleanup (D)] in the [General] tab of the Properties dialog.
If [DirectX Shader Cache] is not [0 bytes] on the right side, uncheck the other boxes, check [DirectX Shader Cache] only, and click [OK].
Click [Delete Files] when the Are you sure you want to delete these files? confirmation dialog appears.

If you are using Discord at the same time, the following settings may be affected.
Click the gear icon at the bottom of the screen and go to User Preferences and try the following:
・Click on [Audio/Video] and turn off [H.264 Hardware Acceleration] in the settings section.
・Click [Overlay] and turn off [Enable Overlay in Game] in the settings section.

The effectiveness of the shader cache depends on your PC configuration, but if you have a high performance CPU and plenty of memory, disabling it may improve performance.
Also, even on the same PC, the status of the shader cache changes depending on the history of the games you have played, so the occurrence of problems may vary depending on the games you play.

We sincerely apologize for any inconvenience this may cause.
We hope you continue to enjoy playing The Legend of Heroes: Hajimari no Kiseki.
