Symptom(s):

When the game or application reports AGP is 'off' or disabled, or Microsoft DirectX* Diagnostic tool (dxdiag.exe) shows AGP Texture Acceleration is "not available" on the display tab, check for an update.

Cause:

If the graphics driver reports all of the video memory is local, the DirectX AGP Texture Acceleration setting shows "Not Available". If some or all of the video memory reported is non-local, the AGP Texture Acceleration setting shows "Available."

Older Intel graphics drivers (production versions 13.0 or greater) report all of the video memory as non-local video memory (AGP memory). Therefore, the AGP Texture Acceleration setting shows "Available."

The latest Intel® graphics drivers (production versions 14.0 or greater) do not report non-local video memory. Instead, all of the video memory is reported as local video memory. Normally, the AGP Texture Acceleration setting shows "Not Available" on computers using the latest Intel graphics drivers because the driver is not reporting non-local video memory.

Solution:

Having the AGP Texture Acceleration setting as "Not Available" is a normal and expected behavior for the Intel graphics drivers (production versions 14.0 or greater). This setting does not need to be made available, enabled, or activated, and does not affect the performance of games or 3D applications.

When a game or application is checking for AGP or AGP Texture Acceleration, it is looking for non-local memory. Generally, local video memory is usually faster than non-local.

Intel recommends contacting the game or application vendor to get a setting or update that allows the game or application to check for local video memory first.
