Well Android I can't say much about but if you wanna see REAL difference ( you never mentioned Linux ? ) then try to run them on a not so up to date system ( for instance an i3 would fairly do ! ) NOW you WILL see the difference
Anyhow I would NEVER use Windows over Linux ( and in fact I only use it if there are no other options available ) or Mac
Wasn't that Alia ?
Dude reading through your message I don't see any problem other than YOU " accidentally " deleted your own files...
To put it simple YOU can help yourself by downloading a full build and if the defaultglobal is fucked then have someone give you a save state to you AFTER you start a new game and create anew save states ( can replace the saved states afterwards )
