DirectX 8.1 Potential Issues in Games That Use Software Vertex Processing
The information in this article applies to:
Microsoft Windows XP Home Edition
Microsoft Windows XP Professional
SYMPTOMS
Under very rare circumstances, games that use the Software Fixed Function Transform and Lighting functionality in DirectX 8.1 may stop responding (hang) while you play a game.
CAUSE
This issue occurs when a minor problem in the Direct3D DrawIndexedPrimitive function is experienced. This problem prevents Direct3D from continuing or from displaying an error message.
RESOLUTION
The only games that are known to experience this issue were discovered during pre-release testing and already include this update with the product release. Therefore, few, if any, customers have to install this update manually. However, a fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply this fix only on computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not affected by this problem, Microsoft recommends that you wait for the next Windows XP service pack that contains this fix.
To obtain this fix, visit the "Download" section of the following Microsoft Developer Network Web site:
http://msdn.microsoft.com/downloads
File name: Dx81b winxp - qfe (q321178).exe
Display name: DX8.1b WinXP - QFE
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
MORE INFORMATION
It is unlikely that you will experience this issue because games that have been identified as potentially having this issue already include the fix.
