Battlefield 3 Slow-Motion Bug

Okay that means you are not suffering the general rubberbanding, lag issues or low FPS? That is a little bit weird, lets see if we can get rid of this issue.

At first, download and install the latest version of Origin at www.origin.com/download (and make sure you have your Origin account ready as well)
If that doesn’t helped, close the origin client and go directly to you origin folder  C:\Program Files\Origin Games. Run the origin.exe in this folder with a rightclick -> run as administrator. 
This worked out in the most cases, if not, try to deactivate your firewall/antivirus software and/or check the online ports of your connection:

TCP: 80, 443, 9988, 20000-20100, 22990, 17502, 42127
UDP: 3659, 14000-14016, 22990-23006, 25200-25300
For specific instructions on how to open your ports, please visit http://www.portforward.com/ or contact your router manufacturer.

Install the newest driver for your video card.

For owners of a NVIDIA videocard, please download the latest physx driver. This could solve your problem. Some players reported that it even helped out with an ATI card.

Go to your custom settings of your video-card software. Disable all extra options for enhanced graphics and set the preferences for AA and anisotropic to “use application settings”.
Set the BF3 graphic options to “low quality” or reduce AA and anisotropic filtering to a minimum.
Launch the game, if the issue is solved, you can try to set the graphic options higher.

Sometimes, this issue can be related to the cloud storage.
Open your Origin client, click on “Show Game Details”. Then you go to the cloud button on BF3 and uncheck the “enable cloud storage for all games” box. Launch the game.
If that helped, you can try to enable the cloud storage after a restart; it might work after with the cloud storage function. Make sure to use the local data when the information box popping up.

Keep us updated soldier!
