renaming the 3D Objects folder would only have a negative effect if you use it for any applications that store data there.
you can use any available folder, or create a new one and use it. when installing games, just choose wherever you want.
if installing through Steam, Epic, Rockstar, etc: you may need to first create base game directories on each drive/partition that you wish to use.
the best option has always been to have a separate drive or at least a separate partition used only for game installations.
this way their install directories can be salvaged even when an OS failure or corruption occurs, your game installations are always easier to find, and they do not add confusing directories/files to your OS drive.
having them on a different disk is an even better option. when Windows is accessing system files at the same time your game is accessing game files, your games drive read/write speed will not be effected because the data is on separate drives.
your audio recordings should also be stored the same way for the same reasons.
