About Direct3d 11
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
Key features of the Direct3d 11 that are enabled through these drivers include:

Direct3D 11 runtime, please install the release version of Windows 7 or Windows Server 2008 R2. Windows Vista users can follow the procedure described in KB 971644 (or KB 971512 for corporate network users). For more details, see Direct3D 11 Deployment for Game Developers.Effects 11The Effects runtime for Direct3D 11 (FX11) is available as shared source in the DirectX SDK. For more information, please refer to Effects (Direct3D 11) and Effect System Interfaces (Direct3D 11) in the Windows Graphics documentation. The Effects 11 source is now located in the samples directory(Samples\C++\Effects11).DirectX 11 Runtime SymbolsThe modern DirectX Runtime is part of the operating system (OS), and symbols for the DirectX components (Direct3D, DirectInput, DirectSound, etc.) are provided as part of the OS symbol packages. DirectX 11 Runtime symbols are included in the Windows 7 and Windows Server 2008 R2 symbols packages available on the Microsoft website. However, we recommend using the Microsoft symbols server instead for the most current and correct set of symbols when debugging DirectX applications.Note that DirectX 11 Runtime symbols for the down-level KB 971644 and KB 971512 update for Windows Vista and Windows Server 2008 are not included in the OS offline symbols package. They can be obtained from the Microsoft symbol server.The Provided D3D9D.dll for Windows XP is Versioned for Service Pack 2The D3D9D.dll that is included in the February 2010 and later DirectX SDKs is versioned for Windows XP SP2. If you use this DLL on Windows XP SP3 with an application that uses the Windows Presentation Framework (WPF), the code in the DLL will assert. This issue does not occur on Windows Vista or Windows 7. If you require only debug output, that is, you do not require symbols, you could also use the checked version of D3D9.dll, which is compatible with Windows XP
