the delayed "Mantle" renderer is now available for the
Windows edition of Battlefield 4
for owners of AMD graphics cards, though
for some reason this comes in advance of the new AMD beta drivers to enable
support of the new API (when they're released they should show up
on this page
). They offer benchmarks to show the performance improvements
seen running the military shooter sequel under Mantle, and the following
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.
