Suggestion below taken 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 Punkbuster.
Go to C:\Program Files (x86)\Origin Games\Battlefield 4 and select pbsv.exe . Choose 'reinstall'
