Freezing / Stuttering After Restart Fix

Constant stuttering is a problem that effects Nvidia and AMD cards. Make sure to download the most up-to-date drivers for both devices.

The freezing / stuttering problem occurs most often after restarting Catalyst after your first session. Part of the problem seems to be related to the priority of the Mirror’s Edge: Catalyst .exe.

How to Fix Freezing / Stuttering – Easy Steps:

These are simple steps you can take to improve performance and avoid stuttering. Try both of these methods in tandem for best results.

Method #1:

  • Turn off all other programs currently running in Windows.
    • Open Task Manager -> Processes
    • End all non-critical background processes.

Method #2:

  • Open Mirror’s Edge: Catalyst. When the game is running…
    • Open Task Manager [or] Alt-Tab to the Task Manager window
    • Select the Processes Tab and right-click MirrorsEdgeCatalyst.exe
      • Go to Set Priority -> Select High Priority

How to Fix Freezing / Stuttering – High Priority On Startup

If alt-tabbing and changing the priority settings is a problem for you, Redditor AnnoyingSourcerer has a solution that launches the game automatically set to High Priority.

  1. Open Notepad (or any word processing program that does not automatically format text)
  2. Paste the following:
    • "C:\Program Files (x86)\Origin\Mirrors Edge Catalyst\MirrorsEdgeCatalyst.exe"
      timeout 20
      wmic process where name="MirrorsEdgeCatalyst.exe" CALL setpriority "high priority"
      wmic process where name="firefox.exe" CALL setpriority "Idle"
  3. Change the first line to match the file path on your computer. Search for “Mirrors Edge Catalyst” if you can’t locate it.
  4. Save the note as a Batch file to the “Origins\Mirrors Edge Catalyst” folder.
  5. Create a shortcut to this NEW file (instead of MirrorsEdgeCatalyst.exe)

Double-click the new shortcut and Mirror’s Edge: Catalyst will begin pre-set to High Priority.
