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.

Open Notepad (or any word processing program that does not automatically format text)

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"

Change the first line to match the file path on your computer. Search for “Mirrors Edge Catalyst” if you can’t locate it.
Save the note as a Batch file to the “Origins\Mirrors Edge Catalyst” folder.
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.
