Overview

D3D9On12

D3D9On12 is a mapping layer, which maps graphics commands from D3D9 to D3D12. D3D9On12 is not an implementation of the D3D9 API, but is instead an implementation of the D3D9 usermode DDI (device driver interface). That means it is not a binary named d3d9.dll, but is named d3d9on12.dll.

When an application creates a D3D9 device, they may choose for it to be a D3D9On12 device, rather than a native D3D9 device (see Direct3DCreate9On12 and Direct3DCreate9On12Ex). When this happens, d3d9on12.dll is loaded by the D3D9 runtime and initialized. When the application calls rendering commands, D3D9 will validate those commands, and then will convert those commands to the D3D9 DDI and send it to D3D9On12, just like any D3D9 driver. D3D9On12 will take these commands and convert them into D3D12 API calls, which are further validated by the D3D12 runtime, optionally including the D3D12 debug layer, which are then converted to the D3D12 DDI and sent to the D3D12 driver.

Note that D3D9On12 is an enlightened D3D9 driver, and there are several places where it receives additional information compared to a traditional D3D9 driver, either to enable it to provide API-level information to D3D12 rather than driver-level information (as is the case for shaders), or to enable interop scenarios. When a D3D9 device is created with D3D9On12, the device will expose an IDirect3DDevice9On12 interface which enables applications to submit work to both the D3D9 API and the D3D12 API with lightweight sharing and synchronization.

For more details about D3D9On12, see:

Make sure that you visit the DirectX Landing Page for more resources for DirectX developers.

How does it work?

The primary entrypoint to D3D9On12 is a custom version of the normal D3D9 driver OpenAdapter entrypoint, named OpenAdapter_Private, where D3D9 provides additional information to the mapping layer. In response to this, like a normal driver, D3D9On12 returns an adapter object, which exposes DDIs to create a device. The device is created like normal, but in addition to the normal DDI tables, D3D9on12 also exposes a set of DDIs defined by the D3D9ON12_PRIVATE_DDI_TABLE which can be retrieved by calling GetPrivateDDITable.

The device object internally uses an instance of the D3D12TranslationLayer immediate context to record commands. Similarly, most D3D9On12 objects are backed by an implementation from the D3D12TranslationLayer library. The code in this repository is largely an adaptor from the D3D9 DDI to the D3D12TranslationLayer library, where the real heavy lifting of converting to the D3D12 domain is done.

Building

In order to build D3D9On12, the WDK (Windows Driver Kit) must be installed, in order to provide d3d10umddi.h to D3D9On12, and in order to generate the D3D12TranslationLayer_WDK project, which hosts some code required to parse DXBC shaders and containers. The D3D12TranslationLayer and its subprojects, D3D12TranslationLayer_WDK and DXBCParser, will be fetched from GitHub when building with CMake if D3D12TranslationLayer_WDK isn't already included, such as by a parent CMakeLists.txt that has already entered that project. The DxbcSigner.dll will be pulled in automatically from NuGet.

If you had a local copy of the D3D12TranslationLayer project, your top level project would look something like this:

cmake_minimum_required(VERSION 3.14)
include(FetchContent)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

project(parent)

FetchContent_Declare(
    d3d12translationlayer
    SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/D3D12TranslationLayer
)
FetchContent_MakeAvailable(d3d12translationlayer)

add_subdirectory(D3D9On12)

At the time of publishing, the D3D9On12 and D3D12TranslationLayer require insider versions of the SDK and WDK. Those can be found here.

D3D9On12 requires C++17, and only supports building with MSVC at the moment.

Usage

Note that in order to use your custom version of D3D9on12 you will also need to copy WinPixEventRuntime.dll (will automatically be placed in D3D9on12's build output) and dxbcsigner.dll along with it.

Why open source?

The D3D9On12 mapping layer is included as an operating system component of Windows 10. Over the years and Windows 10 releases, it has grown in functionality, to the point where it is a complete and relatively performant implementation of a D3D9 driver. We are choosing to release the source to this component for two primary reasons:

  1. To enable the community to contribute bugfixes and further performance improvements, which will improve the stability and performance of Windows 10. See CONTRIBUTING.
  2. To serve as an example of how to use the D3D12TranslationLayer library.

What can you do with this?

There are minor differences between binaries built out of this repository and the versions that are included in the OS. To that end, shipping applications should not attempt to override the OS version of D3D9On12 with versions that they have built. We will not guarantee that newer versions of Windows will continue to support older versions of D3D9On12, since it is an OS component which may be revised together with D3D9. However, developers are welcome to override the Windows version of D3D9On12 for local testing and experimentation.

Compatibility

When possible, we will attempt to maintain compatibility between D3D9 and D3D9On12. One should expect that the tip of D3D9On12's master branch should work nicely with the latest release of Windows 10. Support for configurations other than that are not guaranteed to work.

Data Collection

The software may collect information about you and your use of the software and send it to Microsoft. Microsoft may use this information to provide services and improve our products and services. You may turn off the telemetry as described in the repository. There are also some features in the software that may enable you and Microsoft to collect data from users of your applications. If you use these features, you must comply with applicable law, including providing appropriate notices to users of your applications together with a copy of Microsoft's privacy statement.

  • Text is not displaying in Empire Earth II

    Text is not displaying in Empire Earth II

    I'm developing an unofficial patch for Empire Earth II. I have recently received many messages from players who are unable to play the game, due that the text is not displaying in game. All these players have new laptops with Intel CPUs. Most of these players are refunding their laptops for this reason.

    After reading this page, I learnt that Intel is now using D3D9On12 in their drivers:

    We use a D3D9on12 mapping layer, which maps graphics commands from DX9 to DX12. We do extensive compatibility and performance testing, and partner closely with Microsoft* and ISV’s (Independent Software Vendors) to optimize this solution continuously. Intel has been shipping this solution since our 12th Gen Intel® Core™ processor launch in 2021, and we'll continue to invest heavily in this technology for both integrated and discrete graphics solutions.

    I managed to re-produce the issue on my computer using ForceD3D9On12 d3d9.dll. My unofficial patch already supports d3d8to9, so d3d9.dll could be placed in the game folder and was loaded successfully.

    Screenshots showing the issue:

    image

    image

    Steps to reproduce the problem:

    • Install the game.
    • Install unofficial patch.
    • * Edit file UnofficialVersionConfig.txt and add: UseWorkingDirectoryWorkaround=1.
    • Paste d3d9.dll from ForceD3D9On12 to the game folder.

    * This step is required, so the Launcher copies the game executable to to the main game folder (as EE3.exe), instead of starting the game process from a different location. This is needed because otherwise the game would load d3d9.dll from the SysWOW64 directory.

    As the patch developer, I'm usually trying to fix similar issues myself, using dozens of workarounds, assembly, etc. However this time it looks like the problem is in D3D9On12 itself, so maybe somebody could please check if this can be resolved? After all, the issue is quite serious since players who buy new laptops can't play the game.

  • Claim support for Dither

    Claim support for Dither

    Dithering only really made sense when rendering to reduced bit-depth formats (565, 5551, etc), but DX9 era hardware generally had 8 bit precision in pixel shaders anyway so it was usually a noop when outputting to an 8 bit per channel format. DXVK also chose to simply ignore dithering, so we should be fine to claim support but not actually do anything.

  • Implement new present path

    Implement new present path

    Updating 9on12 present path to more closely mirror what happens in the version of 9on12 that ships with the OS. Among other things, this should allow fullscreen apps to work with this version of 9on12.

    We will need a few new DDIs in order to implement the new Present path. Unfortunately, the existing CreateDeviceArgs doesn't have a concept of versioning. This requires the addition of a new OpenAdapter2_Private DDI so that we can use a new version of the CreateDeviceArgs struct that contains versioning info.

    We also need a new way to handle fetching the privateDDITable as we are now adding DDIs out of sync with the runtime. Old runtimes will still call GetPrivateDDITable which will copy the original 27 DDIs, but newer runtimes will be able to call GetPrivateDDITableVersioned which allows the caller to pass the expected size of the private ddi table struct. Since we don't change the order of the DDIs between versions, this is a safe way to make sure that the runtime always gets the full ddi table that it expects without overwriting regions of memory owned by the runtime.

  • Halo Custom Edition with Open Sauce crashes almost instantly

    Halo Custom Edition with Open Sauce crashes almost instantly

    I don't know if this is the right place to post this. I am using Windows 11 Home Edition 21H2 22000.1042 on my laptop. It has an iGPU with Intel Iris Xe and a dGPU with Nvidia Geforce RTX 3050 Ti. I have read that Intel Iris Xe has removed true D3D9 support in favor of this module, not sure if this is true on Nvidia's end.

    After installing the mod Open Sauce 4.0 onto a copy of Halo Custom Edition, I have found that when opening the game, it loads for a couple seconds and then silently crashes to the desktop. This occurs regardless of whether I have it set to render using the integrated graphics or the dedicated graphics. This crash does not occur if Open Sauce 4.0 is not installed. Nor does it occur if Open Sauce 4.0 is installed but I am using a graphics wrapper (either DGVoodoo2 or DXVK work). Since the crash affects both graphics cards, I'm wondering if this is the cause of the crash.

    There's a semantic difference between how DXVA and D3D12 express the filter ranges and steps for video processing filters such as Contrast, Saturation, etc that was not addressed in 9on12. When enabling Video Processing Enhancement in Video Playback Settings, some video players are affected by this bug, rendering a black screen as processing the brightness/contrast when playing video.

    Hello,

    I've tried all known Intel Iris Xe drivers and they all get the same crash. I did a memory test with the app at https://memtest.org/ and it passed. When I disable the Intel Iris Xe device from the device manager, the problem is solved. The game usually crashes between 4 and 10 minutes.

    The problem is that WPF 3D content will not work on intel graphics without D3D9 support like the iris XE. The first thread I opened was this one: https://community.intel.com/t5/Graphics/Graphics-failure-with-WPF-3D-content-and-Iris-XE/td-p/1415196 It describes the problem in detail.

    As Intel itself could not reproduce this issue I opened another one at the WPF repo: https://github.com/dotnet/wpf/issues/7076

    But now it turned out that Intel can also reproduce this issue: https://community.intel.com/t5/Graphics/3D-rendering-issue-on-12th-gen-Intel-Core-i3/m-p/1407118/highlight/true#M109118

    @IanDunn-Intel @vdwtanner can you please look into this. Looks like more people are getting this problem here.

  • Is there a reason D3DFMT_A32B32G32R32F is marked unblendable?

    Is there a reason D3DFMT_A32B32G32R32F is marked unblendable?

    ref: https://github.com/microsoft/D3D9On12/blob/5af944baee8ba540bd6bbcc07efa68066adb6cab/src/9on12Adapter.cpp#L435

    From what I can tell, R32G32B32A32_FLOAT must be blendable since D3D11.0, so I don't think there's any technical limitation demanding this: https://docs.microsoft.com/en-us/windows/win32/direct3ddxgi/format-support-for-direct3d-11-0-feature-level-hardware#dxgi_format_r32g32b32a32_floatfcs-2
