Not that many games are releasing simultaneously on PC and PS5. Id argue that the concept of optimisation still largely exists for the current gen consoles even if they are using mainly off the shelf parts a desktop does not exist that is largely the same; mainly due to the large pool of shared memory that the CPU/GPU use and the ability to target that specific instruction set and hardware which helps too.
