Upgrade graphics drivers

One of the single most important things a gamer can do to ensure the best gaming performance is to install the latest drivers for his or her graphics card. If you’re a gamer, we’re going to assume you’ve got either an NVIDIA GeForce or AMD Radeon-based graphics card. If so, both NVIDIA and AMD offer the latest drivers for their GPUs on their respective website
Do not rely on the disc that came with your graphics card or the drivers that may be offered by Windows Update. NVIDIA and AMD are constantly updating drivers to enhance performance, fix graphical anomalies, and improve game compatibility. That last point is especially important if you like to grab the latest games as soon as they hit store shelves. If you’re running a game that just came out with an outdated set of graphics drivers that are many months old, you’re likely leaving a ton of performance on the table—if the game even runs properly in the first place.

The reference drivers offered on NVIDIA’s and AMD’s websites will be compatible with virtually every consumer-class graphics card based on one of the company’s GPUs. The reference drivers always incorporate the latest bug fixes and performance enhancements and should be updated regularly. At the very least, upgrade to the latest drivers whenever you pick up a new game, especially if it’s unstable or you see strange graphical glitches.
