# Disabling D3D9EX

## <mark style="color:yellow;">If GUNZ still freezes/crashes despite the previous fixes, we will disable D3D9EX.</mark>

* To disable D3D9EX, start with locating your GUNZ files/folder, usually located at:\
  \ <mark style="color:yellow;">`C:\Program Files (x86)\GG\GUNZ`</mark><br>
* Find and open the `config.xml` file, as shown below.

* Find and change D3D9EX from “true” to “false”.

* Manually save it as “config.xml” on your desktop (not just “config”, you must add the extension too). Once done, drag the file into your GUNZ folder and replace the original config file with the new one.
