How do I unshare system memory? I dont think it was in the BIOS being that I do have onboard but I switched that off and set the shared memory to 0. Maybe windows is wrong but this is what the Vista detailed experience index had to say about it:
Display adapter type NVIDIA GeForce 8600 GT
Total available graphics memory 1535 MB
Dedicated graphics memory 256 MB
Dedicated system memory 0 MB
Shared system memory 1279 MB
Display adapter driver version 7.15.11.6369
Primary monitor resolution 1280x1024
DirectX version DirectX 9.0 or better
Notice the 1.5GB graphics memory, yet only 256 is dedicated? I wouldnt mind if it used another 256 for a total of 512MB but thats half my RAM to the video card!
