Does Ram usage creep up for you?

I am not necessarily blaming Cubase for this. During a work session I may have Cubase open, go on the net etc, but I do notice that whilst I start with about 4 gig in use, by the end of the day, with everything shut down, the machine is on 6 gig.

Currenly I am doing a lot of VST stuff - loading and unloading VSTs.

Not sure why?

Windows itself might be caching modules you’ve used, this memory is released if the system gets close to paging.
