Solved nVidia GeForce 640GT using 25% of system ram!

Hello,

I have a 2GB GeForce 640GT video card. It has 2GB onboard and windows 8 is using an additional 2GB of ram for it. I don't do gaming or heavy rendering. Occasionally I use google earth and a few other 3d mapping apps. I don't see how any of these need 4GB of ram to do this. This 2GB of system memory is 25% of my entire system memory. This card, in an older PC used no system memory under Windows 7.

How can I reclaim this ram? If I cannot, and add more ram will it take even more of that?

nVidia says this is a windows issue and not a driver issue but I cannot find anywhere in windows to tune or change this.

Please see the attached System Information from the nVidia control panel.

Thanks!

The word from MSI (card manufacturer) and nVidia is: This is all Windows' doing. That said this is memory the card *may* use but programs may also allocate from it. I guess its good.
