It has been a while since we saw low overhead APIs in the news, and that's because in recent years we've mostly seen horrendous implementations of Microsoft's DirectX 12 API. But with Saber Interactive's recent World War I am glad to announce that they have returned on a large scale, at least for Team Red.

World War Z is an AMD-optimized title that uses the Volcano API, which has many components The company has taken over great Mantle API. All of this means that it is not surprising that AMD's Radeon graphics cards perform well in World War Z. What's really surprising, though, is the impressive performance, which translates into amazing results over the competition. Let's get to the meaty numbers.
AMD RX Vega 64 outperforms NVIDIA RTX 2080 in the Enabled World War Z volcano by up to 20%
The benchmarks were released by GameGPU and performed with an overclocked Intel Core i9 9900K at 5.2 GHz to address possible bottlenecks remove. Let's start with the most popular resolution, 1920 × 1080, with volcano activation. AMD manages to reach the top three places with Radeon VII, Radeon Vega 64, Liquid Cooled Edition and Radeon Vega 64.
In fact, the resolution of the Vega 64 surpasses not only the RTX 2080, but also the NVIDIA's Mammut RTX 2080 Ti. To put this enormous confusion in perspective, one must remember that a RX vega 64 is available for less than half of the cheapest RTX 2080 Ti.
With the RX 580 we see a similar pattern in the stack They outperformed the twice as expensive RTX 2070 and the RX 570 in front of the GTX 1660 Ti.
At 2560 × 1440 the green team manages to fill the gap a bit. Although the RX Vega 64 still manages to beat out with the RTX 2080 Ti and maintain its lead over the RTX 2080. The RX 580 falls behind the RTX 2070 and sits closer to the RTX 2060, while the RX 570 retains its lead over the GTX 1660 Ti.
Only when we get the Resolution up to 4K, things start to get better. This makes sense, considering that Vulcan's low CPU overhead advantage does not offer much leeway at such a high resolution.
The RX Vega 64 retains its edge over the RTX 2080 while the RTX 2080 Ti scratches its way up the power ladder. The RX 580 now sits closer to the GTX 1070 Ti than the RTX 2060. And the RX 570 manages to work with the GTX 1660 Ti, which it beat at 2560 × 1440 and 1080p.
All-in is a great show for the Red Team, showing what a properly implemented low-overhead API can do, and it's nothing short of amazing. Perhaps there is hope that we will again be interested in low-overhead APIs.
