Mantle is a new low-level graphics API that we’ve been working very closely with AMD on over the last 2 years and it is a major change & improvement to how we are able to program & use modern GPUs in order to get the most out of them.
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!
This update is the first release of our new Mantle renderer, and we will continue to provide more tuning for different types of configurations in future updates. Still, we are really happy with the performance improvements that we are seeing with this update and we believe you will be as well.
Read on for the full details on how to enable Mantle, and some information on the kind of performance gains you can expect.
HOW TO ENABLE MANTLE
In order to use Mantle you will need the following:
-AMD Catalyst 14.1 Beta drivers. AMD will post them here.
-AMD Radeon GPU with Graphics Core Next
-64-bit Windows (7, 8 or 8.1)
If you have the above you will see a new “Graphics API” option in the in-game Graphics Options settings after starting the game, here you can switch between using DirectX 11 and Mantle (remember to restart the game after changing).
If the “Graphics API” option is missing, that means you do not have a compatible GPU and driver and the game will use the standard DirectX 11 graphics API instead.
