Troubleshooting Surface Performance Issues

For general decrease in performance, check the Processes tab of Windows Task Manager to see whether any processes are using large amounts of CPU.

This article provides information about the following issues:

Issue: System Performance Is Degraded

  • If a Microsoft Surface unit runs out of physical memory and the Windows Vista operating system starts paging memory, the system's performance degrades noticeably: animations stop running smoothly, new applications time out in the loading screen as they are starting, contact tracking lags behind, and so on. To help avoid these performance problems, use the Microsoft Surface memory manager to close inactive applications that are still running in the background. For more information, see Managing Microsoft Surface Memory.

Issue: Video Playback Is Not Smooth

  • When a user switches between applications by using Launcher, the applications stay running in the background. You might have too many applications running in the background at the same time (especially Microsoft XNA applications, Microsoft Windows Presentation Foundation [WPF] applications that use BitmapEffects, animations, or media playback). You might also want to analyze how an individual application uses CPU and GPU resources.

Issue: Tracking Is Slower Than Expected

  • When a user switches between applications by using Launcher, the applications stay running in the background. You might have too many applications running in the background at the same time (especially Microsoft XNA applications, Microsoft Windows Presentation Foundation [WPF] applications that use BitmapEffects, animations, or media playback). You might also want to analyze how an individual application uses CPU and GPU resources.

Issue: Applications Start Slower Than Expected

In general, if an application is slow to start, there is an issue with the application code. Check with the developer who wrote the application and use the following articles to help find a solution:
