# NVidia-Shaders-Cleaner 🧹

A PowerShell 7 script that removes ALL shader files (*.nvph) in the NVIDIA DXCache folder in Windows.

Version: 1.0

Filename: clear_nvidia_shaders.ps1

## Preview

![Preview](https://raw.githubusercontent.com/hl2guide/NVidia-Shaders-Cleaner/refs/heads/main/images/preview.png)

## Important Notes

This script applies to a user of NVidia GPUs and does nothing at all

for AMD or Intel GPUs.

NVIDIA Shaders can become corrupted or invalid and need to be rebuilt

by a game or app.

__This script removes ALL shader files (*.nvph) in the NVIDIA DXCache folder:__

_$env:LOCALAPPDATA\NVIDIA\DXCache_

Before running this script check that all PC games and apps that use your

NVidia GPU (hardware acceleration) are closed off and not open and running.

This includes the NVidia App and related processes in the

taskbar (bottom right on Windows desktop).

Any PC games can then recreate the shaders (takes time) as needed

at game startup or otherwise.

## Requirements

The script MUST be `run as Administrator` in `PowerShell 7.5.2` or later to work

as intended.

## Usage

Read the above text and then CD into the correct directory and then to

run the script use:

`./clear_nvidia_shaders.ps1`
