Many games require support for application programming interfaces APIs to function, and to provide a high-quality gaming experience. OpenGL and DirectX APIs are designed to render 2D and 3D graphics. Note The dialog box that displays, and the options for 3D settings, depends on your operating system and the graphics driver you have installed.

Open GL and DirectX settings are managed through your graphics properties. Right-click on your Desktop. Click Graphics Properties 3D. Find the Intel Graphics name that displays on your screen, and follow the instructions provided here for settings.

Click or the section descriptions to expand the content: Attribute Default value Other applicable values

Off default value - Enables vertical synchronization also known as vertical sync or VSYNC. Vertical synchronization allows a frame change to coincide with an analog monitor s vertical blanking interval. This might help reduce or eliminate tearing in the video, but can cause reduced frame rate since the frame change is delayed until the vertical blank interval.

On - Disables vertical synchronization.

A technique that can help to reduce or eliminate visual artifacts such as flickering, tearing, or shearing. This is done using three buffers to minimize the delay in redrawing the image, at the cost of higher memory usage.

Default default value - Driver selects triple buffering based on available memory.

Off - Disables triple buffering.

On - Enables triple buffering.

Flip default value - In applications that run in full screen, enables flip multi-buffering. With flip operations, the render buffer is directly connected with screen and when it is rendered it is just swapped on to the screen with no copying occurring.

Blit - Enables blit multi-buffering which copies rendered buffer on to the screen. With blit operations, several bitmap patterns are combined into one using a raster operator. Applications running windowed not full-screen can only use blit operations.

Depth Buffer Bit Depth Off On

16 Bit Depth Buffer - Forces a 16-Bit depth buffer on PixelFormats that have a depth buffer.

24 Bit Depth Buffer - Forces a 24-Bit depth buffer/8-bit stencil buffer on PixelFormats that have a depth buffer.

Force S3TC Texture Compression Off On

S3TC is a method of texture compression to reduce the texture size, for the cost of lower texture quality and higher processing power demand.

Off default value - Driver does not automatically compress all RGB and RGBA format texture images into S3 compressed format.

On - If S3TC extension is supported, the driver automatically compress all RGB and RGBA format texture images to kept them internally in S3TC format. It reduces the amount of required memory/allows to support more textures.

Force FXT1 Texture Compression Off On

FXT1 is another method of texture compression to reduce the texture size, for the cost of lower texture quality and higher processing power demand.

Off default value – Driver does not automatically compress all RGB and RGBA format texture images into FXT1 compressed format.

On - If FXT1 extension is supported, driver automatically compresses all RGB and RGBA format texture images into FXT1 compressed format.

Driver Memory Footprint Off On

Specifies a preferred bit depth for texture maps on devices that support multiple texture bit depths.

Anisotropic filtering enhances the final image quality when textures are used for surfaces that appear to be non-orthogonal to the screen, at the cost of performance.

Application Control default value - Filtering controlled by the application.

On - Enables anisotropic filtering.

Off - Disables anisotropic filtering.

You can change the value of each OpenGL attribute or restore the default values to all attributes. Select the apply button to save your changes.

Intel DVMT 2.0 Graphics Memory Footprint The driver determines the amount of pre-allocated memory needed and will make additional nonlocal video.

Attribute: Default value: Other applicable values: Driver Memory Footprint. Off: On: Determines how much memory driver uses for resources like textures or buffers.

You can use the Memory Footprint assessment to quantitatively compare a baseline operating system image against another operating system image. You can then identify the specific components that affect the memory footprint of the physical system. These components can include drivers, add-in applications, preloaded software packages, and antivirus programs.

By using the Memory Footprint assessment, you can compare the effect that different hardware configurations and associated software have on system memory. This software can include device drivers and other preloaded software options that start when the system starts. After you compare two system images in a side-by-side review, you can decide to change drivers or optimize the memory footprint of your system in other ways.

This assessment creates a snapshot of memory use during a series of assessment boots of the system and immediately after the appearance of the desktop in Windows  7 or the start screen in Windows  8 Enterprise. It does not evaluate memory use during ordinary computer operations. For more information about the results this assessment produces, see Results for the Memory Footprint Assessment.

The following graphic shows the assessment process. As the graphic illustrates, the assessment requires multiple system reboots to generate all the assessment results.

The first-run help tips in Windows 8.1 can negatively affect assessment results. To disable these, run the following command from an elevated command prompt, and reboot the computer:

reg.exe add HKLM Software Policies Microsoft Windows EdgeUI /v DisableHelpSticker /t REG_DWORD /d 1 /f

Run this assessment only while the desktop is full screen. Do not run this assessment if you have another Windows Store app opened side-by-side with the desktop.

This assessment includes system reboots as a regular part of the assessment process. To configure your computer to run assessment jobs automatically without manual reboots or system prompts, see Automate Reboots Before You Run an Assessment.

You can run this assessment on the following operating systems:

Supported architectures include x86-based, x64-based, and ARM-based systems.

There are two ways to run this assessment on Windows RT:

Microsoft defines the recommended settings so that you can compare the results across multiple computer configurations or over time on the same computer. When you review the results, the run information includes metadata that indicates whether the assessment used the recommended settings.

You can also customize the settings for an assessment, if you want to gather data that is different from the default data. For example, you might identify specific data that would help you perform a detailed analysis of a particular aspect of the computer.

The following table describes the assessment settings, recommended setting values, and alternative values for each setting.

Specifies whether the assessment uses the recommended settings. By default, this check box is selected. To change the settings for this assessment, you must first clear this check box.

Specifies options that you can select to configure the type of memory testing that the assessment performs. These options are as follows:

Full Run. This option provides more-precise results but takes longer to finish. This option uses six preparatory computer reboots followed by a seventh measuring boot to ensure the most accurate measurement of memory usage.

Quick Run. This option does not include the system preparatory steps of the full run. Therefore, it shortens the time that the job takes to run. The information that it delivers is less comprehensive but still useful.

Shows the path of the Microsoft public symbol server for Windows. The assessment uses symbols to make sure that its results show driver memory as driver allocations instead of kernel allocations. Without the use of symbols, the assessment analysis may incorrectly identify a memory allocation source. This can disguise issues and hide driver problems. For more information about the symbol server, see How to: Use a Symbols Server.

If you cannot connect to the symbol server, you can take one of the following steps to ensure assessment accuracy:

Download the symbols and copy them to the computer that you want to assess. This option requires that you provide the path to the local symbols.

Run the assessment on one computer and then load the trace on another computer that has access to symbols because it is connected to the Internet or already contains downloaded symbols. Then, run the analysis by using the analysis-only mode.

For more information about missing symbols and assessment accuracy, see Common In-Depth Analysis Issues.
