CA has done the worst DX12 port in Total Warhammer

[Doom112]

One of the biggest advantages of DX12 – at least according to Microsoft – is its improved multi-threading capabilities. However, as we can clearly see in both the in-game benchmark and our Extreme scenario, the game is unable to properly take advantage of all our CPU cores (again, DX11 graph is on the left whereas DX12 graph is on the right).

This game shows that Nvidia is far better in DX11 in this game compare AMD in DX12.

CA never worked with NVIDIA on DX12 or took their input, which, one of the reasons the results are terrible on DX12. If this goes on then DX12 will have the same faith as DX10 ,therefore, developers need to take this brand sponsorship out and work with both parties.

We’re pleased to confirm that Total War: WARHAMMER will also be DX12 compatible, and our graphics team has been working in close concert with AMD’s engineers on the implementation. This will be patched in a little after the game launches, but we’re really happy with the DX12 performance we’re seeing so far, so watch this space!

Once again sorry for my bad English.

The main purpose of DX12 and its existence is to reduce CPU bottleneck not Async. Async is just a tiny feature of DX12 .


DX12 has failed to do its main feature.

 

[Doom112]

It's because NVidia doesn't support Async Compute in hardware fully on Pascal, and not at all on previous GPU's, and by the looks of it, that's what this patch has implemented.

NVidia does have 'fast context switching', what ever that is it's not a full Async Compute implementation as in the DX12 standard.

Did you look at the DX11 benchmark? Fury X with Async in DX12 is still 30% slower then GTX 980 Ti DX11.

 

[Doom112]

My 970 is also slower in Cryengine 5 running DX12 than it is DX11.

It seems to me they are just not native DX12 hardware, at least not in the same way AMD are.

Cryengine 5 DX12 is also running slower on R9 390.

I honestly don't get what some of you are on about? Look at the graphs and then you might see something that is questionable regardless of AMD or NVidia





So in DX12, the 980Ti and 1080 are roughly 34% faster than the Fury X and in DX11, the 1080 is 86% faster than the Fury X. Hell even the 970 is giving the Fury X a run for the money but some of you guys are missing this and we are getting silly comments like "Nvidia only have themselves to blame" but shouldn't people be looking at the lackluster performance of the AMD cards and questioning why the performance is so bad in the first place and even DX12 isn't helping AMD here?

It just looks like a poor implementation of DX12 all round to me but don't let common sense ruin a good thread.

That is exactly my point.

like Total Warhammer, Hitman is a AMD sponsored game, no big surprise they are performing better.

No surprise but i am really surprise that AMD with Async on DX12 still slower then Nvidia DX11 up 30%.
