InfoPanel Presentmon Plugin

A plugin for InfoPanel to monitor and display real-time frames per second (FPS) and frame times for fullscreen applications using PresentMon.

Features

• Displays FPS and frame times for fullscreen apps (e.g., games).
• Detects active fullscreen applications automatically via Windows API.
• Uses PresentMon for high-performance DirectX metric capture, averaging over 5 frames for smooth output.
• Manages PresentMonService for Event Tracing for Windows (ETW) sessions.
• Ensures robust cleanup of processes and ETW sessions on app exit or InfoPanel shutdown.

4. Copy these files to the plugin folder as described in step 3 above.

Troubleshooting Steps & Error Messages

If the plugin isn’t working as expected, check the InfoPanel logs or UI for clues. Since this plugin doesn’t display error messages directly in the UI like SpotifyPlugin, look at the console output in InfoPanel (or logs if enabled). Here are common issues and fixes:

No FPS Data Showing

• What It Means: The plugin isn’t detecting a fullscreen app or PresentMon isn’t running.
• How to Fix:
  • Ensure your app is in fullscreen mode (not windowed).
  • Check logs for Checked for fullscreen PID: X—if it’s always 0, switch to fullscreen (e.g., Alt+Enter).
  • Verify PresentMon-2.3.0-x64.exe and PresentMonService.exe are in the plugin folder.

Logs Show "Failed to locate PresentMon executable"

• What It Means: The plugin can’t find PresentMon-2.3.0-x64.exe.
• How to Fix:
  • Confirm PresentMon-2.3.0-x64.exe is in C:\ProgramData\InfoPanel\plugins\InfoPanel.IPFPS\.
  • Download from PresentMon releases if missing.

Logs Show "Service setup failed"

• What It Means: The plugin couldn’t start InfoPanelPresentMonService—likely a permissions issue.
• How to Fix:
  • Run InfoPanel as administrator (right-click, Run as administrator).
  • Check if PresentMonService.exe is in the plugin folder.

Logs Show "PresentMon did not exit cleanly after kill"

• What It Means: PresentMon didn’t stop within 5 seconds after being killed.
• How to Fix:
  • Open Task Manager, end any PresentMon-2.3.0-x64.exe processes manually.
  • Restart InfoPanel—shouldn’t persist with v1.1.0.

ETW Sessions Linger (e.g., logman query -ets shows PresentMon_*)

• What It Means: Cleanup didn’t remove an ETW session—rare with v1.1.0.
• How to Fix:
  • Run logman stop PresentMon_<session_name> -ets in an admin Command Prompt.
  • Restart InfoPanel to ensure full cleanup.

General Tips

• Restart: Fixes most glitches—close and reopen InfoPanel.

Still Stuck?

If issues persist, check Task Manager for lingering PresentMon-2.3.0-x64.exe or PresentMonService.exe processes—kill them manually. Open a GitHub Issue with your logs (e.g., last 20 lines after closing the app) and steps tried.
