JPCSP launcher and Large Pages

[montcer9012]

... for some reason launcher is still reporting insufficient privileges.

Number one, RUN THE LAUNCHER AS ADMINISTRATOR.

... After disabling that temporarily, it goes through. And it's not that I lacked RAM. I have 8GB of it.

Other solution besides the one you found will be hit the button "Show all users process"; this will allow you modify the Java priority on Windows Task Manager.
   
Also, i want ask you something because i wonder why you use Windows Page File with 8 GB RAM?; i did wonder it because using Page File will force your HDD make the work that your RAM have to do and when the HDD becomes overloaded system stability decrease a lot (theoretically). In that order MGSP must become slower even on a 7200 RPM HDD!!! However you told that game performance was better using PageFile instead your RAM hahahaha!!
