I play a 3-D game on my laptop that uses about 1.2 GB of RAM, typically. The laptop has 6 GB of RAM, and Task Manager shows approximately 2.5 GB of RAM in use when my game is running.

I have read this thread about why Win 7 uses the page file when there is "free" RAM, and that Windows actually mucks around with the "free" RAM to try and make my future experience better.

However, the problem I have is that sometimes it decides to write some other app out to the pagefile, which causes my game to run very slowly for 30 - 60 seconds. (Apparently my laptop's HDD doesn't write very fast). I know this is what it's doing because I tab to Resource Monitor which I already had open, and see heavy writes to C:\pagefile.sys, but it is still showing only the 2.5 GB of RAM in use.

When I am playing my game I don't want it to try and second guess what I'm about to do, I just want my game to run optimally and preferably nothing else should write to the HDD at all. (My game does do a reasonable amount of HDD reading during normal gameplay, but little to no writing).

Is it possible to instruct Windows 8 to not try to be clever and page out other apps while my game is running?

I don't think you can "pause" the pagefile, maybe turn it off completely...

But you could close as many programs as possible before running your game, that way the pagefile should be quieter while your playing... unless it's your game that's running out of real ram & getting swapped to the pagefile.

Rather than turning it off, I would choose static size and made sure that pagefile.sys isn't fragmented. Defraggler can defrag chosen files.
