Version: 1.0

Filename: clear_nvidia_shaders.ps1

Preview

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
