The problem is, is that you can organize by project by giving each project it's own Desktop and switch between those. Yes, Sets is a different way of doing it and more options is IMO good, but why implement something else that you can already do?
Your described problem seems like normal behaviour. Drops from 90 to 80 is completely normal because the scene is always changing and rendering something different. Putting games on an SSD will help the streaming asset issue if that is what's causing it.
What Windows version are you running? They added GPU in Task Manager in 1709 iirc. Otherwise try re-installing the GPU driver. (also check if you put your display cable in your GPU and not your Mobo )
Yes, it got more to do with "status", oh you only have a Pocophone? pff, you are poor and not part of the "group". If you want to be popular at uni, you need expensive shit to show to people...
I know it's a stupid concept but it happens.
