According to Sony, 100 of the most popular PS4 games run on the PS5 initially. Beyond that, testing will continue and more and more PS4 games will be made compatible with the PS5. PS4 games on the PS5 can be stored on an external hard drive so there is space on the console’s SSD for the next-gen games that require it. How do you see this development?
[UPDATE] Sony makes it clear that most of the 4000+ PS4 games will run on the PS5 unexpectedly, with potential benefits such as a higher / stable frame rate and higher resolution. Each game is tested individually to solve potential problems and hundreds of games have already been tried. Reference to the 100 most popular PS4 games was given as an example of how well the backward compatibility issue is going.
