Disable Superfetch & Prefetch while gaming?

Recommended Posts

Is this a good idea? If so, can we see it implemented into Razer Game Booster? Thanks!



Disable SuperFetch and Prefetch.


Both SuperFetch and Prefetch boost Windows and application start-up times (in some cases, at least!). For games, however, I noticed that loading times and background activity actually increases when both of these Windows caching features are enabled, so I recommend turning them both off if you’re an avid gamer.


To do this, go to “Control Panel”, “System and Security”, “Administrative Tools” and “Services”. Scroll down until you see the “SuperFetch” entry, double-click on it, and choose “Disabled” from the list.








Hit “OK”, and close all of the windows. Next, open up the registry; click on the Start orb, and type in “regedit”. Hit Enter, and go to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters”. Double-click on “EnablePrefetcher”, and enter “0” (default value is “3”) to disable the Prefetcher.

Use Windows resource monitor and go to the disk tab. Sort by disk by total and tell us what exactly is taking up all your disk usage. If it's something like automatic virus scans or large file writes on to your HDD then Superfetch will not help you. Post a screenshot of that disk tab.


Can you actually see Superfetch actually taking up lots of resources like RAM or CPU? If not then forget about it.
