I know i'm a bit late to this chat but I rather post on here than opening a new post but if I read correctly, I can make two seperate versions of GTAV one in steam and one out of steam for modding aka LSPDFR as a standalone. I was going to look into a crack for GTAV for my steam version so i could just make a png icon and rename the folder LSPDFR, without having to screw up the vanilla version and get banned. If i misunderstood, is there a way to make it possible to have 2 different versions of GTAV without having to rename folders when i want to switch?
