The contents of the TS3 user game folder includes certain elements that I would call "inert." There is no real harm or impact on performance for these to stack up because the game and the Launcher don't really read or try to do anything with these files while being loaded up and played, only when they are called upon for actual use. These would include Screenshots, Recorded Videos, and the Library folder that holds our lot and household bins (possibly some others).
However, once we start talking about many thousands of subfolder items each rather than dozens or hundreds, I have to agree that shifting them elsewhere out of the game folder is still a pretty good idea. Insisting that the game folder carries that many items just seems inefficient and possibly asking for trouble if something goes dreadfully wrong with the entire game folder along the way so the "just in case" organization strategy still seems like a pretty good one.
And, at the risk of going off-topic myself, I don't really care how well a different iteration of the game performs if it's one that I do not care to play for other reasons. I mean, I care from an intellectual standpoint and as an observer of how the entire franchise is evolving, but there is no practical point to comparing the two games on a thread such as this one. I don't really care how well GTA would perform on my system either since I know that I would never enjoy playing it. :|
