Integrated Graphics Subsystem

The Microsoft Direct diagnostic tool included in most versions of Windows may be used to check the amount of video memory being used. The Display tab of the utility the “Approx. Total Memory” label will indicate the amount of video memory. The value will vary according to OS (In Windows XP, the video memory size reported by DirectX will always be 32 MB, even if the total memory installed is over 128 MB).

✎Some applications, particularly games that require advanced 3D hardware acceleration, may not install or run correectly on systems using the IGC.
