Crashing, lagging, or won't start? Collection of solutions here!
First off, trying compatibility mode or verifying game files because apparently this had to be said.

---Game fails to start / Crashes without error messages---

Install the latest Nvidia PhysX System Software regardless of whether you are using an Nvidia, AMD or alternative graphics card. AMD Radeon and alternative GPU users who are able to start the game using this method are then advised to disable PhysX in the options menu.

Your monitor may not be supported. Open the engine config file (%USERPROFILE%\Documents\My Games\EA Games\Mirror's Edge\TdGame\Config\TdEngine.ini) and change the resolution. Look for ResX and ResY in [SystemSettings] section) to one supported by your monitor (try 1024x768 if you don't know what your monitor supports)

Relocating the PhysXLoader.dll
\SteamApps\common\mirrors edge\Binaries\PhysXLocal.
In PhysxLocal you'll find the PhysXLoader.dll, copy that, and paste it into \SteamApps\common\mirrors edge\Binaries."

---Lag when glass breaks---
For AMD: Disable PhysX in the options menu.
For Nvidia: Delete or rename the physxcore.dll, and physxdevice.dll from the <path-to-game>\binaries folder. These are an older version of PhysX the game defaults to, and if it isn't there then it'll use whichever version you have installed on your system. Do not delete physXextensions.dll. If this fails to work, disabling PhysX could solve the problem.


With the influx of steam summer sale buyers there are way too many people just starting a new discussion instead of just reading the millions of other threads on the subject. Hopefully this collection of common problems and fixes will give people their solutions without everyone creating their own threads on the same problem, or having to look through all the threads for everyone's solutions. Most of this was ripped straight off of the PCGW site.

Any mods to sticky this or any other solutions threads? legit solution threads keep getting buried beneath all the "EXTREME LAG HELP FIX" and "GAME CRASH WHY" new threads.

Relocating PhysXLoader.dll worked kosher for me.

You are a ♥♥♥♥ing genius. After the training the loading isnt responding and afterthe doing the PhysXLoader.dll thing it works thanks

What is it that you have to rename it to? Just have that you rename two files, but not what to rename it to. Please specify.

@ flyingangel08
It doesn't matter what you rename them to. Just change the name so the program won't use the outdated files.

Thanks for the help nuh1. The game runs like a dream now.

Don't let this get buried! Seeing more and more crashing threads pop up again. Hopefully this stays fairly close to the front page of discussions.
