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.

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
