I'm using a dell studio 15 lap with i3 processor 4GB DDR3 and windows 7 64-bit. In my display adapter details, its showing Dedicated Video memory : 1024 MB System Shared Memory : 1722 MB Will it affect my system performance? Can I disable the system shared memory? My system sometimes shows some slowing, thats why i'm interested in disabling the shared memory. Is there anyway to do it?
