    Ah yes indeed. Still "sad" for people who already done the game.

    It's a pity Kepler DX12 isn't supported. I tried it anyway and it starts, but the game freezes at a black screen after loading the mission.

    DX12 made wonders already in Hitman 1 for this old Phenom II X4.


    Actually, Hitman 2 DX12 does work on Kepler now. The latest Nvidia driver mentioned a fix for Hitman 2 crashing, so I tried the game again and now it works in DX12.

    What would we be benchmarking against? Different Nvidia models?

    And future Intel models and future AMD models.

    Of course. The point was there's no comparison yet, no way to quantify the efficiency of a GPU doing VRS compared to others.

    That’s useful enough by itself, right?

    Wolfenstein Young Blood and the Modern Warfare remake will use VRS. UL is just catching up with game developers.

    It's about as useful as the PCIe 4.0 test.

    But didn't Intel already show this test in their Ice Lake Gen11 GPU presentation?

    I know where your coming from, but these tests are showing real improvements which once game engines start tapping into, will give us more eye candy. In case of PCIe 4 we have been there already with PCI, AGP x1 x2 x4 x8, PCIe 1.0 2.0 ...
    If we were to go back now to AGP x4 with our modern game engines I think you would spot the difference ;)

    For now obviously it is a feature which gives something to professionals working with huge data sets, but for gamers it's a non-important logo on a box. In the next 5 years it will be of benefit even in games.
    I personally won't upgrade my Threadripper motherboards because of PCIe 4.0 as I have enough lanes not to be bothered with it, but when I decide to do it, it will be nice to be able to visually verify that it works as intended and tests like this are one way of doing it.

    But ... PCIe 5 might come before I will do that!

    The thing is this test doesn't seem to be made to simulate realistic scenarios. It's made to show the tech's potential in an ideal scenario. We already have real in-game implementations for variable rate shading, and they don't show nearly as much of a performance upgrade as this test implies:

    Actually this test allowed me to see that my x99 - Vega combo has terrible pcie performance, even if it's running at pcie3 16x :neutral:

    Yes, only 5.2 GB/s here, a little bit better with HBCC enabled, round 7 GB/s then.

    Does anyone have any insight into why the PCIE speed test requires DX12?

    Glad it's not a bug on my setup then. Still strange...

    Stardock (the developer of the first ever DX12 game: Ashes of Singularity) has recently posted a blog post explaining why they abandoned DX12/Vulkan in their newest game: Star Control, in favor of DX11.

    It basically boils down to the extra effort it takes to develop the DX12/Vulkan path, longer loading times and VRAM crashes are common in DX12, if you don't manage everything by hand. Performance uplift is also highly dependent on the type of game, and they only achieved a 20% uplift on the DX12 path of their latest games, which they say is not worth all the hassle of QA and bug testing.

    In the end, they advice developers to pick DX12/Vulkan based on features not performance, Ray Tracing, AI, utilizing 8 CPU cores or more, Compute-Shader based physics ..etc.
