thanks for quick reply. I hear what you say about them not caring about offline mode. Man I am so paranoid about it.. So I can just boot off the clean folder? then restart game with modded one offline? And they won't about registry keys (ex. openIV so forth?) hum... months building this account i might just use a friend's old account then...

I have a completely separate hard drive with OS installed to test modding in GTA V . Being a removable drive, I can just swap it out with the non modded GTA drive. So my question is how can i go GTA V offline steam. I tried the -scOfflineOnly option putting a command.txt in the folder but still without internet the social club does not allow it to start.

I get that it is possible to first boot up with an umodded GTA folder, then close game then boot game with Modded folder but that seems kind of risky in that the system can still be scanned for OpenIV, or whatever registry keys might be about. Is there a way to boot offline, without internet at all? If so how ?

Thanks
