; Memory Strategy setting
; This setting affects the way memory is being allocated for the Java
; virtual Machine. Balanced means that memory will be allocated in a
; blanced manner for heap, stack and objects.
; Heap only is the "old fashioned" way of binary edited il2fb.exe files
; where only the heap memory size is getting increased while all other
; memory areas remain untouched.
; Conservative is a setting right between Balanced and Heap only.

; default setting: 0 (Balanced Mode)

; Cached File Lists setting
; When this setting is enabled, IL-2 on startup does not scan the modded files
; folder anymore, but uses a filelist cache file for this folder if it exists.
; The filename for this cache file is "~wrapper.cache".
; Every time when you change something inside your modded files folder, you
; have to wipe this file for the game to recreate it with updated contents.
;

; Multiple Instances setting
; Usually you can run only one single IL-2 instance at a time.
; When you enable this setting, you can run IL-2 multiple times in parallel.

; When enabled, IL-2 selector will quit when you exit the game.
