Hi, I've been trying ways to increase PermGen for my private modpack with close to 400 mods, but the thing is that I heard too much permgen is bad and too little will cause severe fps drops after 10 minutes of playing (which is what I'm experiencing now). So is there a way to customise the permgen and permgenmax to 256 and 512 from the launcher?
This is what I typed in the Java Arguments box exactly
-XX:PermGen=256M -XX:PermGenMax=512M
No colons, case sensitive, space sensitive.
I'm not sure if this is working, but before I move on to another fix, is this the right way to edit permgen?
