Which Performance Monitor counter should you use to troubleshoot poor frame quality for a current user session on Windows 11 Enterprise multi-session session hosts?

The correct answer is RemoteFX Graphics. This Performance Monitor counter set provides detailed metrics specifically related to the graphics rendering and encoding processes within a RemoteFX session, which is fundamental to Azure Virtual Desktop. Poor frame quality directly indicates issues in this graphics pipeline. Terminal Services Session provides general session statistics but lacks the granular graphics detail needed for frame quality troubleshooting. GPU Engine monitors the physical GPU's activity, but doesn't directly show the quality of the rendered frames being sent to the client. Terminal Services is a broad category encompassing various aspects of remote desktop services, but not specific enough for diagnosing frame quality.
