Vulkan, Direct3D 11 and Direct3D 12 renderer for Unreal Tournament

OpenXR Vulkan/OpenGL on Direct3D 12 interoperability layerThis software enables OpenXR apps developed for Vulkan/OpenGL to work with OpenXR runtimes that have support for Direct3D 12 and not Vulkan/OpenGL.DISCLAIMER: This software is distributed as-is, without any warranties or conditions of any kind. Use at your own risks.SetupDownload the latest version from the Releases page. Find the installer program under Assets, file OpenXR-Vk-D3D12.msi.For troubleshooting, the log file can be found at %LocalAppData%\XR_APILAYER_MBUCCHIA_vulkan_d3d12_interop.log.LimitationsThis has only been tested with Windows Mixed Reality.This has only been tested with NVIDIA and AMD video cards.Vulkan support has been tested with BeamNG, the X-Plane 12 Demo, the HelloXR sample app from Khronos, Unity 2021, Godot 4, Adobe Substance 3D and Enscape 3D.OpenGL support has been tested with HelloXR sample app from Khronos, Autodesk VRED 2024 and Paraview.It is compatible with OpenXR Toolkit.Known issuesApplications using legacy XR_KHR_vulkan_enable must enable Vulkan timeline semaphores at device creation time.

The necessary code to Y-flip the image is not implemented.If you are having issues, please visit the Issues page to look at existing support requests or to file a new one.OpenXR ConformanceThe API layer passed all OpenXR conformance tests (at v1.0.26.0) with Vulkan as the graphics API and with Windows Mixed Reality at the backing OpenXR runtime.How does it work?This API layer sits between any OpenXR application and the OpenXR runtime. It enhances the currently selected OpenXR runtime with the OpenXR extensions necessary for Vulkan support (XR_KHR_vulkan_enable and XR_KHR_vulkan_enable2). It uses the OpenXR runtime's Direct3D 12 support to efficiently bridge the application's Vulkan rendering to Direct3D 12. This processes does not add any overhead: the swapchains (drawing surfaces) requested by the application in Vulkan formats are imported as-is from Direct3D 12, there is no additional copy nor composition phase. Upon submission of the rendered frame, a simple fence synchronization primitive is inserted in the GPU queue shared with the OpenXR runtime, which will not block the application's rendering loop.Same principle applies to OpenGL support.

How to Fix Direct3D errors Thread starter Thread starter jbrown156 Start date Start date Oct 2, 2014 Tags Tags Direct3D Directx tutorial Many computer games, as well as some 3D modelling programs, rely on the Direct3D component of DirectX to render graphics. If your computer has a problem with a DirectX file or a graphics driver, it can cause these programs to crash or not open. Windows includes a tool for testing your DirectX installation, and you can solve most issues by turning on hardware acceleration or updating DirectX and your video driver.InstructionsChecking the DirectX Installation1 Press "Windows-R" and enter "dxdiag" to run the DirectX Diagnostic Tool.2 Open the "Display" tab to see the status of Direct3D and other graphics components in DirectX.3 Read the "Notes" box to learn about any errors with Direct3D. If DirectX is installed correctly, it will read "No problems found."4 Read the "Feature Levels" line in the Drivers section to see which versions of DirectX your video card supports. Programs that require a version other than those listed will not work on your computer.5 Check the DirectX Features section to make sure each line reads "Enabled." If any line does not, you need to enable hardware acceleration.Enabling Hardware Acceleration6 Right-click the desktop and choose "Screen Resolution."7 Click "Advanced Settings."8 Open the "Troubleshooting" tab and click "Change Settings." Enter the administrator password if prompted.9 Slide the "Hardware Acceleration" option to "Full."Updating DirectX and Video Drivers10 Run Windows Update from the Control Panel to install updates for DirectX 11, available on Windows versions dating back to Vista. On Windows 8, Windows Update is the only method to update DirectX 11. On Windows 7 or Vista, you can alternatively download the updates manually (links in Resources).11 Download and open the DirectX End-User Runtime Web Installer (link in Resources) to update DirectX 9. DirectX 9 installs and runs separately from DirectX 11, and many games require it even on systems with DirectX 11 installed.12 Install the June 2010 version of DirectX 9 (link in Resources) if the Web Installer reports you already have an up to date version but you continue to have trouble with DirectX 9 applications. This offline installer includes every update to DirectX 9 and will reinstall over your existing copy, potentially fixing its problems.13 Update your video drivers either through Windows Update or by downloading drivers from the Nvidia, ATI or Intel website, depending on your graphics hardware.

Faster cores so that people on lower specced hardware can use runahead with more frames in advance.CRT Switch Res – GroovyMAME-like features for 15KHz capable CRT monitors!Thanks to forum-user Alphanu, RetroArch now has the ability to query cores for their exact video timing data, which can be used to switch to native-resolution, 15 kHz modelines for use with standard-definition CRT TVs.This is a big step for retro purists, as RetroArch can now output “pixel-perfect” video with accurate timing to compatible displays, even quickly switching between interlaced and non-interlaced modes on the fly.This capability is currently Windows-only and requires modelines to be created in advance by CRT_EmuDriver or Custom Resolution Utility with a compatible GPU. Linux support is coming soon.In case you’d like to learn more, follow these links:ATI CRT EmuDriver15Khz CRT documentation WikiDirect3D improvements, additions, and a new Direct3D10 driverWith RetroArch 1.7.1, we really stepped our game up to finally start treating Windows as a first-class citizen platform. You have seen this in the form of dedicated Direct 3D 11/12 video drivers that had the ability to run the same shaders as Vulkan, our new slang shader spec that is made possible by the impressive Khronos/ARM-backed project SPIRV-Cross.Increased backwards compatibilityPreviously, the Direct3D 11 driver required that your graphics card driver supported at least Shader Model 5.0. We have since downgraded this requirement to Shader Model 4.0. As a result, I am now able to use the Direct3D 11 video driver on an old 2010 laptop GPU that only supports Shader Model 4.0 (it’s an ATI Mobility Radeon HD 4300). We also try to support more D3D11 feature levels instead of just defaulting to 11.0.New Direct3D 10 video driverOn some systems, though, you won’t be able to make use of the Direct3D 11 driver no matter what. One of those systems happened to be another old laptop I had lying around here. This one has a Geforce 9200M GS, and the specs state that it supports up to Direct X 10 and Shader Model 4.0. Direct3D 11 is a no go on this GPU even with the increased backwards compatibility.It’s for this purpose that me and aliaspider spent some time to finally make the Direct3D 10 driver feature-complete. Direct3D 10 should be available from Windows Vista and up, whereas Direct3D 11 is available from Windows 7 and up. The Direct 3D 10 driver should be feature complete and identical to the Direct3D 11 driver, with the sole exception of hardware rendering contexts not being available right now with Direct3D 10.Which brings us to the last Direct3D-related subject…Direct3D-powered libretro cores are now possible!This feature is easily worth its own article, but since we already covered this before and because 1.7.2 has so many huge features, we will relegate this to a side note. Nevertheless, it is none the less important.Up until now, if you wanted to use hardware-accelerated 3D rendering in a libretro core, your options were OpenGL and/or Vulkan. There is now a third option – Direct3D 11, and the first

5.x development series. The Wine C runtime is updated to support linking to MinGW-compiled binaries; it is used by default instead of the MinGW runtime when building DLLs. Graphics: Multiple display adapters and monitors are properly supported, including dynamic configuration changes. The Vulkan driver supports up to version 1.1.126 of the Vulkan spec. The WindowsCodecs library is able to convert more bitmap formats, including palette-indexed formats. Direct3D: Fullscreen Direct3D applications inhibit the screensaver. DXGI swapchain presents inform the application when the corresponding window is minimized. This typically allows applications to reduce CPU usage while minimized, and is in some cases required to allow the application window to be restored again. Switching between fullscreen and windowed modes using the standard Alt+Enter combination is implemented for DXGI applications. The following features are implemented for Direct3D 12 applications: Switching between fullscreen and windowed. Changing display modes. Scaled presents. Swap intervals. These features were previously already implemented for earlier versions of the Direct3D API. The handling of various edge cases is improved. Among others: Out of range reference values for the alpha and stencil tests. Sampling 2D resources with 3D samplers and vice versa. Drawing with mapped textures and buffers. Usage of invalid DirectDraw clipper objects. Creating Direct3D devices on invalid Windows, like the desktop window. Viewports with a minimum Z larger than or equal to the maximum Z. Resources bound through both shader-resource views and render-target or depth-stencil views at the same time. Blits between formats with and without alpha components. Since well-behaved

Important Changes from Direct3D 11 to Direct3D 12 - Win32 apps

Microsoft plans to usher in the next-generation of gaming realism with DirectX 12 and graphics tool set Direct3D 12, the company announced at GDC 2014.For consumers, this developer-focused API translates to PC, console and mobile games with richer scenes, a higher on-screen object count and full use of their modern graphics cards.DirectX 12 is intended to work across all of Microsoft's platforms including Windows 8, Xbox One and Windows Phone 8.Promising benefits like reduced GPU overhead and better render efficiency, this overhauled, closer-to-the-metal API software should lead to more balanced game performance.Best of all, this still-in-development balanced performance can be sought on existing computer hardware. The DirectX update won't require an upgrade for 80% of "gamer PCs" currently being sold, said Microsoft.DirectX 12 release dateMicrosoft's upbeat DirectX 12 compatibility claim is important because it wants users to keep buying PCs that run the Windows 8.1 operating system as well as the Xbox One.It's not like waiting around for the DirectX update isn't a viable option for most gamers who want to build a new gaming rig right now.Sign up for breaking news, reviews, opinion, top tech deals, and more.Microsoft demoed Xbox One's Forza Motorsport 5 on PC with console-level efficiency. The tech demo of this photorealistic racing game wouldn't be possible on the PC without DirectX 12.However, DirectX 12 and Direct3D 12 aren't supposed to launch until holiday 2015. A preview version is expected later this year.By the DirectX 12 release date, we should have Windows 9.
