Shaders manage how pixels are displayed on your screen, and misconfiguration often creates problems with the display. If you’re not familiar with ‘shaders,’ think of them as the directors of a gaming scene. They instruct your computer’s graphics card on how to display each pixel on your screen, influencing everything from color to depth and lighting. ‘Optimization’ refers to the process of making these shaders run as efficiently as possible, ensuring your game looks great and runs smoothly.

MW2 automatically optimizes shaders to prevent this, yet you can restart shaders manually if the optimization gets stuck.

  1. Launch MW2 and open Graphics Settings by selecting it in the Settings dropdown menu.

  1. Click on the Windows icon, type Device Manager, and open it.
