So why did you disable your pagefile (and superfetch for that matter) again?
I've disabled it for the same reason I'm an agnostic. Just because I don't see any evidence whatsoever, doesn't mean I can't remain open-minded. On the off-chance that some game or application might prefer to use my pagefile rather than my physical memory, I'd rather have it disabled and respond if the game is unstable or doesn't behave.
I've had little use for alt-tabbing in Skyrim - and I generally don't alt-tab in any game. I've learned that a lot of games SEEM friendly to it, but then they start to become unstable or delayed after a while. So I generally avoid it.
Should be pretty obvious
As for Superfetch, I prefer not having superfluous processes optimising load-times when the gain is trivial. I recommend Superfetch to people using their computer for work or who launch the same set of applications over and over again. But since I tend to launch only a single game at a time, I don't find much use in the initial load being optimised.
If you like your browser to start up slightly faster or whatever, I guess I can see the point.
But overall, the gain is minimal for me - personally - and since I can't be certain it doesn't interfere with my gaming, I prefer it to be disabled. It seems to provoke a lot of excessive harddisk activity at strange times. Me no likey.
That said, I mostly disable it out of habit - because I didn't always have 12 gigs of memory available. Superfetch reserves around 500 megs pr. default for its optimised loading (or it did in the beginning, at least) - and I didn't want that to interfere with anything.
I feel the same way about file-indexing, which is also disabled. It's 100% irrelevant to my needs. But it's great for work.
(I do know that I've had games like Falcon 4 refuse to launch without a pagefile). I used to disable it on XP but it seems to be a boon on Win 7, rather than a hinderance. Same with superfetch actually.
Well, Falcon 4 is ancient - and did use a shit-ton of memory during the dynamic campaign. It sounds reasonable that they wanted to ensure people had enough memory for that growth.
Still, not something I've personally experienced.
