We all know that PCs are more powerful than consoles but the key word here is optimisation. Optimisation is the process of checking and altering a game to ensure it runs on a certain platform as expected. This costs the developers and publishers a good chunk of their budget by having to run test after test ensuring each stage of the developed game works on different hardware, and its easier to optimise for two consoles, the Xbox One and the PS4 than rather a million combinations of components. If games were only ever created and optimised for consoles, it would quite frankly save developers time and money, hopefully invested back into making the game even better.
