Direct2D is a

hardware-accelerated, immediate-mode, 2-D graphics API that provides high performance and high quality rendering for 2-D geometry, bitmaps, and text. The Direct2D API is designed to inter operate well with Direct3D and GDI.


provides support for high-quality text rendering, resolution-independent outline fonts, and full Unicode text and layout support, and much, much more.

DXGI 1.1

builds on DXGI 1.0 and adds several new features including support for Direct3D 10.1 command-based remoting and support for synchronized shared surfaces.

They have also introduced XNA Math, which provides developers a cross-platform native-code method of generating SIMD instructions. One of the most important ones computes shader processing techniques that can be run on a D3D10 or D3D11 GPU. It is also available as DirectX End-User Runtimes.

Direct3D 11 is out and ready for use by your game today to exploit the latest in video hardware features as well as current generation machines. This talk brings you up to speed with the API, offers tips on how to get your renderer up and running, presents key feature overviews, and shows how to deploy your application. Attending this talk is highly recommended if you are attending other DirectX 11 presentations.

You can download Directx 11 from this official Microsoft download page. It needs Windows Genuine validation to download. You can also download a run time environment for end-users here (Web Installer)

DirectX hardware acceleration allows your application to utilize a client machine’s video card (integrated or dedicated) to render DevExpress controls. DirectX acceleration boosts applications’ performance on 4K displays, where large data applications rendered with standard GDI+ can be unresponsive.

DirectX applications require the Windows 7 Platform Update (with DirectX 11), Windows 8 or newer. However, we do not recommend Windows 7 because the CreateSwapChainForHwnd method takes a DXGI_SWAP_CHAIN_DESC1 structure that has a field for Scaling. The DXGI_SCALING_NONE Scaling is not supported on Windows 7 with the platform update. As a result, the CreateSwapChainForHwnd method returns DXGI_ERROR_INVALID_CALL when called. This causes the DirectX-rendered Data Grid to jitter when users resize the form.

Enable DirectX Hardware Acceleration

You can enable DirectX rendering in the DevExpress Project Settings window.

To enable DirectX rendering, you can also call the static WindowsFormsSettings.ForceDirectXPaint method when the application starts.

The ForceDirectXPaint method enables the DirectX hardware acceleration for the following controls:

  • Editors when used for in-place data editing in Data Grid. The Rich Edit Control is not supported.
  • Vertical Grid and Property Grid

To revert individual controls to the GDI+ engine, disable their UseDirectXPaint settings.

The following DevExpress controls’ default UseDirectXPaint value is equal to DefaultBoolean.False. For these controls, calling the static WindowsFormsSettings.ForceDirectXPaint method alone has no effect. You should call the global static method and manually set their UseDirectXPaint properties to DefaultBoolean.True to enable the DirectX acceleration.

  • CalendarControlBase descendants (for example, CalendarControl)
  • TextEdit-based editors that support Advanced Mode (see the RepositoryItemTextEdit.UseAdvancedMode property).

To use DirectX rendering in the PDF Viewer control, enable the PdfViewer.RenderPageContentWithDirectX property.

To use DirectX rendering for the DocumentViewer control, enable its UseDirectXPaint property. The WindowsFormsSettings.ForceDirectXPaint static method has no effect for this control.

Hardware Recommendations



Applications benefit from DirectX acceleration on any display, but these advantages are more evident at higher resolutions (2K, WQHD, WQXGA, 4K, etc.).

Virtual Memory

Each control painted in DirectX mode requires its own DirectX device. You can set the optimal DirectX device number through the DevExpress.Utils.DirectXPaint.DirectXProvider.DeviceLimit property. If the current device number is equal to or higher than this DeviceLimit property value, new controls that need to be shown will still be painted with DirectX acceleration. However, the application tries to release devices for currently hidden controls to keep the number of active devices below the threshold, which reduces the total virtual memory consumption.


API Limitations

DirectX hardware acceleration imposes the following restrictions on the API:

Unsupported API

Recommended Action

All API accessed through the e.Graphics property (for example, when handling custom draw events).

Utilize the GraphicsCache class API (available through the e.Cache property).

  • DirectX has no methods that accept image attributes. Instead, utilize the GraphicsCache methods that accept the ColorMatrix objects as parameters.
  • Methods that take Regions as parameters have no counterparts in GraphicsCache. Use methods that work with rectangles instead.
  • All GraphicsUnit enumeration values are treated as GraphicsUnit.Pixel.

Methods that use the Graphics class objects as parameters (for instance, the ControlPaint class methods).

No replacement, use similar methods instead.

The AppearanceObject.CalcDefaultTextSize(Graphics g) method overload

Replace with the AppearanceObject.CalcDefaultTextSize(GraphicsCache cache) overload

The following AppearanceObject.CalcTextSizeInt method overloads:

  • CalcTextSizeInt(Graphics g, StringFormat sf, string s, int width)
  • CalcTextSizeInt(Graphics g, string s, int width)

Replace with the following overloads:

  • CalcTextSizeInt(GraphicsCache cache, StringFormat sf, string s, int width)
  • CalcTextSizeInt(GraphicsCache cache, string s, int width)

The following AppearanceObject.CalcTextSize method overloads:

  • CalcTextSize(Graphics g, string s, int width)
  • CalcTextSize(Graphics g, StringFormat sf, string s, int width)
  • CalcTextSize(Graphics g, StringFormat sf, string s, int width, int height)
  • CalcTextSize(Graphics g, StringFormat sf, string s, int width, int height, out Boolean isCropped)

Replace with the following overloads:

  • CalcTextSize(GraphicsCache cache, string s, int width)
  • CalcTextSize(GraphicsCache cache, StringFormat sf, string s, int width)
  • CalcTextSize(GraphicsCache cache, StringFormat sf, string s, int width, int height)
  • CalcTextSize(GraphicsCache cache, StringFormat sf, string s, int width, int height, out Boolean isCropped)

The AppearanceObject.FontHeight property is obsolete

No replacement for this property. Revisit your code and use a different approach.

The Pen.Alignment property is ignored.

There are no DirectX-compatible counterparts for this property.

Custom fonts

Custom fonts that you use may be absent on users’ machines. For that reason, use system fonts only.

The InterpolationMode property in Graphics, GraphicsCache, and RepositoryItemPictureEdit classes supports only HighQualityBicubic and NearestNeighbor values.

CompositingMode, CompositingQuality, TextRenderingHint, SmoothingMode, and PixelOffsetMode properties in Graphics and GraphicsCache classes are ignored.

To detect all the unsupported APIs, call the static WindowsFormsSettings.ForcePaintApiDiagnostics method and set the security level as the first parameter:

  • Throw - unsupported APIs result in exceptions;
  • Trace - unsupported APIs display result in warnings, displayed in Visual Studio’s “Output” window;
  • Disable - ignores unsupported API;
  • Default - acts as “Trace” if DirectX andor Per-Monitor HiDPI support is enabled; otherwise, as “Disable”.

The ForcePaintApiDiagnostics method’s second parameter allows you to specify a custom behavior:

Other Limitations

Metafile images are rasterized in DirectX mode. As a result, such images can appear blurry if stretched or zoomed.

Test Mode

DevExpress DirectX rendering is available only for graphics cards that support Direct3D Feature Levels equal to or higher than 11. To check your GPU’s supported Feature Levels, run the “DirectX Diagnostic Tool”: press “Win+R” to launch the “Run” dialog and type in the dxdiag command. Alternatively, in Visual Studio go to “Help About Microsoft Visual Studio” and click the “DxDiag” button.

You can enable the Test Mode if your machine has Feature Levels of 10_2 or lower. This mode forces the application to use the DirectX rendering regardless of supported Feature Levels. Note that this mode is intended for debugging only.


You can also set the DirectXRenderLogMode property to RaiseDeviceCreationFailedEvent and handle the DeviceCreationFailed event to trace all cases when the application is unable to create a DirectX device.
