Deus Ex Mankind Divided DX 12 Performance Review

1080p Testing

For this set of testing, we are using gameplay from Deus Ex Mankind Divided, as the game’s built-in benchmark was found to misrepresent the performance impact of the new API. It is expected that this new API will affect different areas of the game differently, but these results are consistent with testing that we have conducted on other areas of the game. 

As you can see in the graph below DirectX 12 has a negative impact on average framerate performance on all GPUs except the GTX 1060 Strix, though all averages are within 1 frame for the majority of tested GPUs. 

On Nvidia’s GTX 980Ti we found that the performance impact of DirectX 12 was hugely negative, lowering average and minimum framerates by around 10%. Looking at AMD’s RX 480 and R9 Fury X we can also see that average framerates drop slightly, but minimum framerates also increase by between 2-6 FPS.
