The latest update to Battlefield 4 on the PC saw the long awaited release of AMD's Mantle platform which is set to bring significant performance increases on selected AMD cards.
Frostbite team technical director, Johan Andersson, explains what Mantle is all about.
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.
He continued by saying that the biggest gains will be seen on systems that were being bottle-necked by the CPU power.
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!
If you want to take advantage of the new Mantle technology you need to make sure that you have the following things:
- AMD Catalyst 14.1 Beta drivers
- AMD Radeon GPU with Graphics Core Next (Note: AMD Catalyst 14.1 initially supports the AMD Radeon R9 290X, R9 290, R7 260X and Kaveri APU)
- 64-bit Windows (7, 8 or 8.1)
If you do meet these requirements then you will see an option in Battlefield 4's graphics settings to switch from DirectX 11 to the new Mantle platform.
Let us know if you see any performance increases or any general thoughts you have on the new mantle platform.
