How to fix Path of Exile Shader Cache Lag Spikes / FPS Drops - Standalone Version

I'm playing the standalone version, and I improved my FPS by doing this, based on this forum thread:

"If the Shaders bar alerts you about shader loading/saving being critically slow, consider changing the drive that the shader cache is stored on to a faster one.
In the [GENERAL] section of the settings file, you can set
cache_directory=x:\path\to\preferred\location
to a folder on a faster drive.

English:
Open the following path in File Explorer to edit the game's configuration file:

%USERPROFILE%\Documents\My Games\Path of Exile

Look for the file named:

production_Config.ini

Open it with Notepad or any text editor.

To set a custom cache folder, add the following line under the [GENERAL] section:

cache_directory=X:\your\preferred\folder

(cache_directory=P:\PoECache)

🇺🇸 Step-by-Step in English
1. Open Notepad
Create a new file and paste the full script.

2. Save as .bat file
Save with the name:
poe_cache_setup.bat
Choose “All files” as the file type.

3. Run as Administrator
Right-click the .bat file and choose “Run as administrator”.

4. Choose your Graphics API
The script will ask which API you want:

1 → DirectX 11

2 → DirectX 12

3 → Vulkan

5. What the script does automatically:

Deletes old shader cache folders and symbolic links

Creates new folders in P:\PoECache

Sets up symbolic links in the correct location

Also links the Minimap folder

TESTING: %APPDATA%\Path of Exile or C:\Users\<username>\AppData\Roaming\.

I'm new to the game, this is my second league, so if this is against the rules, I would like to be informed about it. I don't know much English, any spelling mistakes, disregard.
