Deus Ex Mankind Divided DX 12 Performance Review

Conclusion

Deus Ex's DirectX 12 update can sadly be called nothing short of a disappointment, with the new API delivering less performance on Nvidia GPUs and lower average framerates on AMD hardware. Yes, AMD's minimum framerates do increase slightly, but these performance gains are often as little as one or two FPS, which is so low that they are almost meaningless.    

On Nvidia's Pascal GPUs the performance decrease is minimal, often being only 1-2 FPS lower in DirectX 12 than it was in DirectX 11, but it is still a decrease, which leaves us recommending that all Nvidia users stick to DirectX 11 in this particular title. On Nvidia's Maxwell GTX 980Ti we found huge decreases in GPU performance, which were as high as 15% in some cases, which means that users of older Nvidia hardware should definitely avoid using the DirectX 12 API in Deus EX Mankind Divided.    

Eidos Montreal had originally promised that DirectX 12 support would come to Deus Ex, but even now as it is officially added to the game the game it still feels like a beta option that could use some extra development time. There will be future updates to Deus Ex: Mankind Divided that will deliver extra DirectX 12 optimisations and eventually DirectX 12 multi-GPU support, but for now the game DirectX 12 support is disappointing. 

This mirrors the early DirectX 12 performance of Rise of the Tomb Raider, which did not offer any significant performance gains early on but over time became much more usable as the Crystal Dynamics continued to deliver more DirectX 12 oriented performance patches and fixes. 

All-in-all Deus Ex: Mankind Divided's DirectX 12 version still feels incomplete and does not offer performance gains that are consistent with other DirectX 12 titles. Right now we would only recommend that AMD GPU users play Deus Ex: Mankind Divided in DirectX 12 as Nvidia hardware only offering lost performance. Even on AMD hardware the performance benefits that we see with minimum framerate are so small that they will be unnoticeable to most players, so even now DirectX 11 is still a great option for AMD users.  

Hopefully, Eidos Montreal will continue to update their DirectX 12 implementation moving forward, as we would certainly like to see this demanding new title get a little but easier to run on PC.

lmao so nothing has changed and it's actually worse.

TBH? DX12 is turning out to be ball suckingly bad. So much PR and promises and BS.

This gen of console "ports" absolutely friggin' stink man. I just hope devs get to grips with it all soon because I am really starting to avoid games which is not like me at all.Quote

I don't understand why you keep complaining. No game has been built entirely on DX12 based engines. You aren't going to see the benefits.

In addition, you'd be better off testing with slower CPUs vs faster CPUs to see if it's actually helping. That's where benefits come from, DX12 is all about the CPU, being GPU limited in both cases doesn't showcase anything besides the fact that if they are equal performance in DX11/12 then it's actually working correctly. Any gains would be marked as very successful.Quote

I see a boost with my Sli of 980ti from dx11 to dx12. I test with ultra preset and Msaa off. At 3440x1440:

DX11:
Avg 46.3
mini 37.2
max 56.3

DX12:
avg 63.0 (+36%)
min 51.9 (+39%)
max 74.6 (+32%)Quote

That is a huge performance gain there, sadly I do not have two matching GPUs to test, otherwise I would have tested it.Quote

I have seen a guy in my Deus Ex MD bench thread get a nice performance increase with DX12 SLI 1080s.

Having said that was it really DX12 itself that gave the increase as it all that has really happen is SLI scaling has improved a bit. I have seen much better SLI scaling in DX11 with other games when the game and drivers have been good in the first place.

The other thing that is concerning is 980 Ti's and 1080s are NVidia cards, they have poor hardware DX12 support to start with so are we really just looking at an improved SLI profile.Quote
