DirectX 12 Explicit Multi-GPU Performance Review with Ashes of the Singularity

One of the most exciting features of the DirectX 12 API is how it handles Multiple GPUs, allowing Multi-GPU setups to be much easier to utilize in games and if implemented correctly can allow GPUs from multiple manufacturers to be used together in a single system.

Ashes of the Singularity is the first game to receive this functionality with DirectX 12, allowing any two DirectX 12 GPUs to be used together in an AFR (Alternate Frame Rendering) Configuration, allowing even AMD and Nvidia GPUs to work together, or two GPUs from a different product series.

In this review we will be looking into DirectX 12 Explicit Multi-GPU inside Ashes of the Singularity, focusing on the performance changes when using non-matching GPUs together in DirectX 12. We have also looked at the performance impact of DirectX 12 in the a different article, looking into the impact of features like Asynchronous compute.

What is Ashes of the Singularity?

Ashes of the Singularity is an all new RTS (Real-Time Strategy) game that is based in a post-technological singularity universe in which humans have begun to colonize the stars.

In this game humanity now faces a new foe that threatens to completely annihilate them, this race is the Substrate, a race of machines that seeks to control the same fertile and habitable worlds that humanity trying to claim for themselves.

Drivers

For this game we will be using the newest drivers that were available when the game released, which is Nvidia's Game Ready Geforce 361.91 driver and AMD's 16.1.1 Hotfix driver, both of which became available to the public in the past month.

Test Setup

We will be testing this game on our dedicated GPU test rig using the current flagship GPUs from both AMD and Nvidia. Both GPUs will be the reference design and will be ran at stock settings.

AMD R9 Fury X & Nvidia GTX 980Ti

Intel Core i7 6700K @ 4.7GHz

ASUS Maximus VIII Hero

G.Skill Ripjaws 4x4GB DDR4 3200MHz

Corsair HX1200i

Corsair H110i GT

Windows 10 x64

To represent AMD and Nvidia's Mid range GPU offerings we have decided to use the AMD R9 380 and the Nvidia GTX 960. Both of these GPUs will be the ASUS Strix models

Both of these GPUs offer very similar performance in most scenarios and come in at very similar pricepoints, so it will be very interesting to see which GPU will come out on top.
