During today’s “Road to PS5” presentation, PS5 lead system architect Mark Cerny ran through a lot of technical details regarding Sony’s upcoming hardware. Though the event seemed geared more towards developers than consumers, it did clarify some information about one of the topics gamers are passionate about: backwards compatibility.
Cerny revealed that PS4 (and PS4 Pro) backwards compatibility is a native part of the PS5 chipset, and that it isn’t a scenario like the PlayStation 3’s backwards compatibility, which essentially just included a copy of the PS2 in every console until the feature was removed in later iterations.
“Once backwards compatibility is in the console, it’s in,” Cerny says. “It’s not as if a cost-down will remove backwards compatibility like it did on PlayStation 3.”
However, that doesn’t mean that every PS4 game will automatically work perfectly out of the gate. Cerny says that running PS4 titles at boosted frequencies can cause complications in certain games. “The boost is truly massive this time around, and some game code just can’t handle it,” he says. “Testing has to be done on a title-by-title basis.”
So what PS4 games can you play on your PS5? Cerny says that “almost all” of the top 100 PS4 games (as ranked by play time) will be available at launch. Presumably, tests on individual games will continue beyond that to continue broadening the library.
All of this pertains specifically to PS4 Pro and PS4 titles; Cerny did not mention anything about whether PlayStation games from earlier generations will also work on PlayStation 5.
