I was actually fairly disappointed when Visual Studio (not code) went to 64-bit. Because I knew its memory usage was now going to be unconstrained. Still way better than the unapologetic gluttony of Rider but experiences showed it to be a bit leaky over time (tip: Ctrl-Alt-Shift-F12 twice does a full garbage collection https://learn.microsoft.com/en-us/visualstudio/ide/visual-st...)

Also remember that all your references (pointers) are going to double in size so right off the bat it will use more, potentially a lot more depending on how reference-heavy your data is

Why did I know that that link went to Raymond Chen before clicking it... That man is a treasure.
