    Yay context. The idea that Steam itself was rendering something or affecting Vulkan/DX12 performance was a bit :???:

    Seems a bit faster than D3D11 now. At least for my setup.

    Steam has the overlay and some in game components that could cause problems. Especially for resource management, but yeah rather basic unless capping framerate to refresh or something.

    Seems a bit disingenuous to exclude the exclusive DX12 titles when that's the only way to properly implement the models. API by all appearances works well, just Win10 adoption is a bit lackluster. Vulkan however has been rather impressive.

    Well I can relate why they are omitted.
    Quantum Break was a DX12 exclusive and then done later to support DX11, where ironically showed decent optimisation.
    In fact fair to say the DX12 experience for Nvidia was pretty bad, resolution probably down to the Nvidia engineers sorting out some of this in DX11 and their drivers.

    On the flip side, surely there are some good exclusive DX12 titles that are clearly optimised-designed well for both AMD/Nvidia, but without DX11 it is difficult to know just how well.
    I wonder where that leaves Nvidia with their DX12 Gameworks/libraries, will that end up being either an incentive or another issue in eyes of devs-studios.

    The article didn't exclude any DX12 exclusive title, they count them in like any other.

    Did Nvidia ever explain or anyone found out what they did to gain up to 20% performance in Forza 7 with DX12 and a driver patch (387.92)?
    Just curious if it was an issue Nvidia side or like both manufacturers do with DX11 overcome possible issues/inefficencies with the game code affecting them.

    The only public announcement I found associated with Forza 7 and Nvidia driver patch update was:
    Goes to show though how performance can be skewed just looking at launch, still relevant for consumers but as benchmarks something that needs to be monitored when talking about it a new game or actual benchmark.

    Why do they bother? Marketing checkbox?

    Yup, most developers just write "work in progress" under the toggle of DX12 and be done with it. Even Verminitide 2 is no exception to this. It's like this is their scapegoat, even 2.5 years after DX12 release!

    D3D12 is hard and time consuming, but it's a marketing requirement.

    That's curious. Please, do expand.

    Is this something that major dev teams agreed upon during conferences? Is it being pushed by publishers?
    Are games with a DX12 label selling better on the PC?


    They certainly seem to be confident on overtaking DX12.

    PCgameshardware.de published their results now. They say DX11 is better when GPU limited, and DX12 is better when CPU limited. They note that DX12 generally is better as soon as there are more enemies on screen.

    We just don't have enough Carmacks in this world ... too many incompetents trying to jury rig decade old codepaths into DX12/Vulkan, piss poorly.

    Actually they state fps under DX12 is generally lower than DX11, especially min fps. However DX11 seems to be limited @1080p for some reason while DX12 is not. Which is kind of a moot point when you are testing the game with high end GPUs that will operate @1440p or higher.

    The WHVT-results are a bit inconklusive, I think. While the 1080 Ti and Vega56/64 gain even in low resolutions from using DX12, the GTX 1070 appears a bit slower, also the RX 580, even though it's only a tiny bit here.

    Battlefield V Alpha: Our First Gameplay Benchmark Results

    "But finally, after two long days of benchmarking, we compiled comparisons between DirectX 11 and DirectX 12 performance, a look at the various graphics quality presets, an analysis of run-to-run variance, and benchmarks for Nvidia’s five highest-end Pascal-based GeForce cards.
    ...
    There’s a post up on EA’s Battlefield V Closed Alpha forum flat-out guiding players toward the DirectX 11 default setting. Specifically, “…we recommend using the defaulted DX11 setting as this build is a work-in-progress and using DX11 will improve performance.” To verify, we compared runs under both APIs using the Ultra quality preset on our MSI GeForce GTX 1070 Ti Gaming 8G."


    [​IMG]
    "Naturally, we expect EA DICE to continue refining Battlefield V’s technical foundation. What’s interesting, though, is that the game is based on a well-established Frostbite engine. It’s not clear what Battlefield V adds that’d negatively affect performance under DirectX 12 to such an extent."
