How to improve computer performance when you play Microsoft games

This article contains information to help you improve the performance of a computer when you play any one of the games that is listed in the "Applies to" section.

Symptoms of poor game performance may include the following:

• Intermittent playback of video clips
• Slow video frame rates
• Choppy game play
• Choppy or poor-quality video display
• Distorted audio playback

Method 1: Analyze the computer components

Some games, such as Flight Simulator X, can determine the performance capability of your computer and adjust to that level as required. However, if you manually adjust the game settings to a level that your video card and processor cannot handle, you will see a slowdown in the performance of the game.

We recommend that you make any game adjustments one at a time to determine whether each change makes any difference. To make adjustements, open the game, click Settings (display), and then turn on or turn off a setting.

Note A computer that has a base score of 4 or 5 can run all the new features of Windows Vista with full functionality. This same computer can support high-end, graphics-intensive experiences, such as multiplayer and 3D gaming. and the recording and playback of HDTV content. Computers that have a base score of 5 were the highest performing computers that were available when Windows Vista was released.

Other Windows editions

If your computer runs on an edition of Windows other than Windows Vista, you can use any of several third-party Web sites to determine the speed of your hardware, including the video card, the processor, the memory, and the hard disk drive. These Web sites include benchmark tests that you can review.

Method 2: Restart the computer by using a clean startup

When you start Microsoft Windows, typically there are several programs that start automatically and run in the background that may interfere with the game. These programs may include antivirus and system utility programs. When you perform a clean startup, you prevent these programs from starting automatically.

You must be logged on as an administrator or a member of the Administrators group to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
