I've played most Rockstar titles, but never multiplayer. I don't understand how a lack of security means they're only playable on uncracked consoles. That sounds backwards. I've only ever played them on uncracked consoles. (and it's not just "yet", I just don't crack any consoles I own)
The performance is good enough for any of my purposes. I don't doubt it could be better.
The security thing sounds like a real problem. I didn't know about any of that.
