How to Update a Shader on a Computerby TS Jordan
A "shader" on your computer is a part of the display driver that helps to shade objects on the screen. To update a shader, you'll use your operating system's Device Manager to update your entire video driver, resulting in additional performance and bug fixes. The process takes around five to 10 minutes.
Click "Start" and click "Control Panel."
Click "Device Manager" and open the "Display Adapters" menu.
Click on your display adapter, select "Drivers" and click "Update Driver."
Select the location of your computer where the new driver file containing the updated shader information is stored. This will install the new driver (and the shader model) to your system.
Reboot the computer.
