I googled it, and the top result wanted to download/install a PuP.
Check Steam. It lists minimum system requirements on each games store page at the bottom.
As someone who released a game on Steam, I had no idea what to put in as the minimum requirements. I basically said “screw it” and put in the specs of the PC I started developing it on because I had no way to test it on anything else.
Starfield CPU requirement is “Intel Core i7-6800K or newer”. I ran the game at nearly constant 60FPS on an (unsupported) i7-4790K.
Sometimes the requirements are bullshit.
