Question about Windows Explorer

Hi,In common with many folk following the FSGS experience I have 2 hardware profiles - Normal and Gaming.Ever since these were set up some two years ago I have noted a certain sluggish behaviour in Explorer operations while operating under the Gaming profile. By sluggish I mean it takes longer for folder trees and folder contents to be displayed than it does under my Normal hardware profile. The latter is always quite zippy and slick. However, under the Gaming profile and following the brief initial delay, once you have browsed a tree and folder contents associated with that tree, subsequent operations on that tree are much faster and more akin to the speed seen under my Normal profile.I mentioned this to Michael Greenblatt at the time and he was surprised at this finding, so I didn't pursue the matter. In any case, my day to day operations are conducted under the Normal profile so it wasn't a big deal. However, despite this, wondering what the cause might be has continued to nag at me.So, to my question: Can anyone tell me what determines the speed of Windows Explorer operations? Indexing Service is disabled on all drives and applies to both hardware profiles, so, in this instance, it's not that.Mike
