How do I update video drivers?

One of the most common reasons a computer will have difficulties running OptiShot is because it does not have the most recent video drivers. 

Computer manufacturers do not continually update the video drivers for the computers they sell. Because of this, it is not uncommon for a two year old computer to be unable to run the latest graphics intensive software such as video games and the OptiShot Simulator. For this reason, it is important to get video drivers from the actual graphics card manufacturer. The problem with this is that graphics card manufacturers try to detect the driver currently installed on computers. If they find a driver from the computer manufacturer installed, they will deny you their latest version.

The directions below get around these checks and will help you the latest version possible for your video card.

STEP 1: FIND THE NAME AND THE MANUFACTURER OF THE VIDEO CARD

1. Click Start
2. Click in the Search box found at the bottom of the Start menu and type dxdiag and hit Enter.
3. On the DirectX Diagnostic Tool click the tab labeled Display.
4. From the Device section write down the Name and Manufacturer.
