How do I set a processor affinity on a multi-core processor in Windows?

Setting Processor Affinity in Windows

Why would you want to set a processor affinity for P2 viewer? It seems that the multithreading in the application has a few bugs, occasionally causing problems with playback speed and sound sync. Setting the affinity sometimes solves this problem.

Here's what you'll do:

  1. Launch P2 Viewer
  2. Right click on an empty part of the taskbar and select "Task Manager"
  3. Find "P2Viewer.exe", right click, and select "Set Affinity..."
  4. You will see checkboxes next to all the cores and processors available to Windows. Deselect all of them except CPU 0
  5. Click "OK" and exit task manager

If that doesn't work, you can try restarting Windows or using an older version of P2 Viewer.
