I noticed that even if I'm using the 9600GT video card, the 256MB shared ram for the 9400M is still in use. Is this suppose to happen? I thought the 9400M would release the 256MB of ram or at least reduce to something not 256MB. I only have 4GB and I'm constantly above 3.3GB of Wired/Active memory along with 2GB - 4GB of paging. That little 256MB would help a lot in not making me lagging under some conditions.
