Vista is using too much shared video memory

[Guest]

Hi I have a Core 2 duo,intel d946 motherboard,geforce 7600gs 256mb and 2gb
rams.Vista is telling me that I have 500mb shared video memory added to the
256mb of the geforce card,I tried to see if I can decrease this in the bios
but it was already set to its minimum of 128mb and not 500mb!! Is there any
way under vista to decrease shared video memory? its obvious that its vista
which is abusing so much rams,I need to use a maximum of rams for 3D sofware
rendering like vue6 that don't use at all the video memory but rams,thank you
for your help

And of course you have shut off the onboard graphics in the BIOS since you
have a seperate Video Card installed.....?????????????????????????/

Yes it's set to PCIE card and DVMT to 128mb not 500mb!

AFAIK Vista reserves a minimum of 512MB more memory then your graphics card
has onboard so that it always has memory available to create the output
buffers required to pass data to your card. So the memory remaining is the
amount available for non graphic applications.
