GMA500 under Windows 7 32 bits

Hello all,

 

I have a hardware based on a US15W chipset (containing a GMA500) with 1 GB of DRAM and I want to use it under Windows 7 32 bits.

Furthermore, I want to have OpenGL 2.0 support.

 

I have two solutions :

  1. Install the Intel Graphics Media Accelerator 500 Driver version 5.0.0.2030 : then, I don't have any OpenGL 2.0 support and the driver locks 150 MB of memory.

  2. Install Intel Embedded Media and Graphics Driver (EMGD) version 1.5 (XPDM mode) : then, I have OpenGL 2.0 support and the driver locks 320 MB of memory.

 

The issue is : when I install the same EMGD 1.5 driver on the same hardware, but under Windows XP SP3, then the driver doesn't lock any memory.

 

I test the OpenGL 2.0 support using the following tool : http://www.realtech-vr.com/glview

I test the memory usage of the driver using the following tools : Windows Task Manager + http://technet.microsoft.com/en-us/sysinternals/ff700229


Does anyone have a clue for this memory usage difference, or a hint to lower it ?

 

Thank you.

Best regards,

Vincent
