Hi @WilfrodBrimlu, what directX error crashes have you been having?
In the meantime heres some suggestions to try:
-Do a repair install of the game in Origin. In origin right click your game and from drop down choose repair install.
-make sure that you've updated your drivers to latest version - or revert to a previous driver.
If its Nvidia then go to the Nvidia website and download the latest graphics driver. http://www.nvidia.com/Download/Find.aspx?lang=en-us
Choose a 'clean install' (usually in the advanced install options)
If the problem only began after updating your graphics driver then try reverting to a previous driver (again choosing 'clean install)
-Make sure you are running the latest PhysX driver:

Answer from eabastien:
Please download the latest physx driver. Go to your custom settings of your video-card software. Nvidia Control Panel > Configure Surround > PhysX > PhysX settings > select your graphics card. Disable all extra options for enhanced graphics and set the preferences for AA and anisotropic to “use application settings”.
-Reinstall DirectX.
1:go to C:\Program Files (x86)\Origin Games\Battlefield 4\__Installer\directx\redist
2:Find file named DXSETUP.exe and right click on it and choose RUN AS ADMINISTRTOR. Install it. It should update your DirectX install.
3: You might need to reboot computer first.
4: try to launch game.
-Update your Microsoft .NET framework.
