The DirectX 12 patch is out and the cards have been put to the test, Nvidia & AMD GPUs tested & benchmarked with surprising results. The DirectX 12 patch for Eidos Montreal’s latest feature title Deus Ex: Mankind Divided has been an eagerly awaited one and for good reason. The futuristic first person story driven RPG is one of the most visually stunning we’ve seen yet but it’s also one of the most demanding. This is one of the few games that, we’re told, that has been designed and developed with DirectX 12 in mind.

Following several other successful and not so successful DirectX 12 game launches of late, gamers looked forward to Eidos Montreal’s latest title to do Microsoft’s low level API justice and deliver on the performance and visual quality promises. And today we can report that it has indeed delivered on those promises, so long as you’re a Radeon user. As sadly, the current situation with Nvidia hardware is not satisfactory to put it lightly.

Deus Ex: Mankind Divided DX12 Benchmarked On Nvidia & AMD – Performs Poorly On GeForce

The DirectX 12 patch has been released a few hours ago and several publications have published performance data on on a collection Nvidia and AMD hardware. Guru3D‘s data shows a 5-15% improvement in performance on AMD ( RX 480, Fury X & R9 390X ). Surprisingly however, on Nvidia hardware performance actually dropped with DirectX 12 compared to DirectX 11.

The GeForce GTX 1080 saw its performance cut significantly at 1080p and slightly at 2560×1440 and 4K. Its little brother the GTX 1060 saw no performance loss or gain on average at the three aforementioned resolutions. However in our internal lab testing the GTX 1060 exhibited the same issue, losing performance at DX12 compared to DX11. The GTX 980 saw some performance loss at 1080p and 2560×1440 with no change at 4K.

DSOGaming report similar performance degradation with Nvidia GeForce graphics cards as well, recommending that Nvidia users avoid using DirectX 12 “at all costs” until the issue is resolved. The development team published a statement concerning the performance degradation that we’ve seen on Nvidia GPUs. Revealing that indeed there’s currently an issue affecting high end GeForce GPUs in particular that has been identified and is being addressed.

Known DirectX 12 issue:
– There is a known bug that causes some very high end cards to regress relative to DirectX 11. This bug is being addressed by the development team.

So for the meantime we recommend that all Nvidia users stick to DirectX 11 to avoid any performance loss.

DirectX 12 Patch Notes

As of today, users are also able to utilize the awaited DirectX 12 Graphics API. To activate this you are required to do the following:

  • Within your Steam Library, right-click on Deus Ex: Mankind Divided.
  • Select ‘properties’ from the context menu and navigate to the Beta tab.
  • From the dropdown menu, select dx12_preview then close the window.

After the game has downloaded the DirectX 12 supported build you can then toggle DirectX 12 from either the launcher window or from the Display options within the game.
Note that DirectX 12 requires a restart of the game if (de-)activated from within a running Deus Ex: Mankind Divided game session.

o WARNING: Using the DirectX 12 API can offer better performance on some systems, however, it will not be beneficial on all.
o Multi-GPU is not yet supported in this patch.
o If you encounter problems with DirectX 12, we recommend turning it off again. There are no visual or gameplay differences between the two DirectX versions.
o As always, make sure that your drivers are up to date:

Known DirectX 12 issue:
– There is a known bug that causes some very high end cards to regress relative to DirectX 11. This bug is being addressed by the development team.

While we expect this patch to be an improvement for everyone, if you do have trouble with this patch and prefer to stay on older versions, we have made a Beta available on Steam, v1.0_build524.6, v1.0_build524.7, v1.1_build524.10, v1.2_build524.15 and v1.3_build524.17 that can be used to switch back to previous versions.
