Battlefield 4 Mantle Update Released

EA's Battlelog announces 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 explanation:

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.

Dude, one more time: EA has purportedly received US$ 8 million from AMD for implementing Mantle support. They did not do this because they thought it would be cool to do or because they care about gamers. They did this for the $$$.

Utterly irrelevant. It doesn't matter why EA did it, it matters that all future EA games will have Mantle support. Unless you're going to argue that EA games are a tiny piece of the market? Regardless of how you feel about EA (not a fan, myself) the fact is that they produce a big percentage of the most commercially successful games out there.

We all know how much the big publishers care for and love their PC ports, right? What makes you think that anyone -without being handed similar bribes- will voluntarily support Mantle? That won't happen. What might happen is that MS and Sony will specifically start bribing devs to NOT support Mantle on the PC version as they already do when it comes to keeping the quality of PC ports on the lower end of the spectrum.

Did you not understand the bit about AMD chips being in both the XB One and PS4? I don't know if you have any business experience, but as a rule companies do not generally bribe people to make their own products look worse. The quality of PC ports simply isn't relevant to the discussion.

AMD are clearly going to push Mantle onto the consoles (they've already said as much).

Mantle is going to be a total niche that will only be supported by games where AMD coughed up a bribe (like BF4) or by indie/KS developers who want to support Mantle to attract some extra attention to their games.

So, once again... your "tiny niche" includes every new EA game, Star Citizen and probably Thief. Yeah, there's no money there at all. Rolleyes

I don't know if Mantle is the real deal or not. If it really does work like AMD are saying, given that devs are already struggling with the limitations of the new consoles, explain why you wouldn't implement something that gives you performance improvements on most of your target platforms.
