Superfetch and gaming?

Lately I've been wondering if other people have had issues with Superfetch and gaming. Now I've always understood that Vista will use nearly all or all of your ram for superfetch and other features but that it would free up the ram when needed. But for me this doesn't seem to be the case. I've noticed when playing games I will get a slowdown/stutter and it seems to happen when I have 6000mb of cached ram and only 50mb or less of free ram.

I have turned superfetch off and played a few games for a little bit and now don't notice the slowdown. So what I'm wondering is if anybody else has needed to do this or if maybe something is wrong with my superfetch.
 
just keep superfetch off.. its useless.. its pretty much there for people that work in offices that are always loading the same programs over and over.. takes the load time out when you open the program.. so instead of waiting 15 seconds for microsoft word to open.. you wait 5 seconds..

also what is your swap file size set at? if its less then 6 gigs total then thats probably why.. since there is not enough space for vista to offload the ram cache to a physical drive.. but anything from 4-6 gigs should be enough..
 
I've had my page file set at 0, 2GB, 4GB, 8GB, and 16GB and had the issue with each setting.
 
Intresting, can't say I've had or seen that problem, and In my tinkering on my first vista build (this build infact, before windows 7 came along), I did try messing with superfetch to see if this newfangled feature form microsoft did anything. In short, yeah I noticed a couple speed ups, and I never noticed a slowdown in Crysis (which was the game I was playing at the time).

--I mean, crysis was slow, we were talking 2GB of ram and an 8800GTS, but I didnt notice a difference with it on or off.
 
You like myself have 8GB of ram (even 4GB shouldn't be an issue) so it shouldn't be a problem. The only time that I did have a problem is before I got my OC stable and my rig wasn't dumping memory properly even though I was linpack, memtest 3.8, 86+, prime small fft, and blend stable.
 
My overclock should be stable. I haven't ran memtest in a while but I have with this overclock, and I ran a 6 hour test with orthos a week ago and it was good. I'm not seeing much of a performance loss with superfetch turned off but if I do maybe I'll try turning it back on and setting the page file again.

Try prime large fft with all of your ram enabled under the custom section. Hyper Pi is another good one for testing MCH stability. Linpack does an ok job, better than prime with mch stability at least.

It seems to happily fork over RAM for me on Vista 64... I can't say I've ever had it cause trouble for me and my 4gb
