I just wanted to share this for anybody who is having problems activating
-XX:+LargePages
You've probably seen on other posts that you have to modify permissions using either gpedit or secpol to allow locking pages to memory. I did the same but for some reason launcher is still reporting insufficient privileges.
Number one, RUN THE LAUNCHER AS ADMINISTRATOR.
Simple nuff.
Number two, MAKE SURE YOU FREE YOUR MEMORY OF AS MANY UNNECESSARY APPLICATIONS/SOFTWARE AS POSSIBLE.
In my case, I got kind of excited when I managed to enable largepages successfully as there is a remarkable boost on the game I was playing(peacewalker). Then one day, it stopped working. Everytime I try to run launcher with largepages enabled, jpcsp wouldn't even launch.
I found the culprit was my antivirus(kaspersky). After disabling that temporarily, it goes through. And it's not that I lacked RAM. I have 8GB of it.
Apparently largepages needed the ram it was going to use to be contiguous. I thought only hard drive memory considered this. I was wrong. I guess some software "scatter" themselves all over RAM?
