While Mantle support has been added in today's Battlefield 4 update, it still isn't able to be used until AMD rolls out a new video driver. Until then, DICE details all you need to know about how to enable it within the game and what to expect once it's enabled.
Battlefield 4 on PC is already quite heavily optimized using DirectX 11 and DirectX 11.1, but with Mantle we are able to go even further: we’ve significantly reduced CPU cost in our rendering, efficiently parallelized it over multiple CPU cores and reduced overhead in many areas.

The biggest performance gains can be seen when the game is bottlenecked by the CPU which can be quite common even on high-end machines and this was main goal to improve on with Mantle. We’ve also been able to streamline and optimize some of the GPU workload. The end result is that game performance is improved in virtually all scenarios in Battlefield 4 on both Windows 7 and Windows 8 when running with Mantle.

You will need the 14.1 Beta drivers from AMD once they are released. You will need an AMD Radeon GPU with "Graphics Core Next". You will also need a 64-bit version of Windows, be it 7, 8, or 8.1. Once these are all met, you can then select "Mantle" from the in-game video settings under "Graphics API."


What kind of gains might you expect from Mantle? Here are some of the results from a test DICE conducted on their own.
