I liked this movie a lot. Yeah, it’s kinda silly in its concept, but the execution of it was deeply satisfying.

I’ve heard that KDE has a cube effect

I use Mint for my main gaming PC, FWIW, totally rock solid

Another thing you might want to try is Mint with the Mate DE, which is based on old GNOME 2 code (and therefore can load the old add-ons like the 3D desktop cube etc)

I’d recommend CachyOS if you’re trying to squeeze the best gaming performance out of the hardware
