Sony has just updated its verbiage on backwards compatibility for the PS5 in an update on the official PlayStation blog , stating that it now intends to support the "majority of the 4,000+ PS4 titles" with backwards compatibility on the next-gen system. Initially, lead system architect Mark Cerny stated during a presentation earlier this week that "[Sony] recently took a look at the top 100 PS4 titles as ranked by play time, and we're expecting almost all of them to be playable at launch on PS5."

The reason for the delay in support for all PS4 titles is due to the PS5's boosted frequencies which will run PS4 games at higher, more stable framerates and potentially higher resolution. Sony is testing each game on a title-by-title basis to ensure compatibility with the updated architecture and work with the original developers if any adjustments need to be made.We already got a glimpse of how the PS5's added power and SSD will improve load times last year featuring Marvel's Spider-Man, and it will be interesting to see just how much better some of the PS4's more demanding titles actually fare.This updated announcement follows the first real deep-dive look at the architecture of the PS5 where we learned about what to expect out of the upcoming system's power, graphical capability, and significantly reduced load times thanks to custom SSDs Cerny also spent a significant portion of time on the 3D audio that will be included in PS5, which will allow for developers to build "new dreams" and immerse players in more meaningful audio due in part to the PS5's custom Tempest audio engine. Cerny even alluded to custom audio designs being developed based on photos and videos of your ears in the future.There's currently no timetable as to when the remainder of the PS4 library will be playable, but Sony claims to have tested hundreds of titles, and will continue testing thousands more as we move closer to the PS5 launch date.See how the PS5's specs stack up against the Xbox Series X and read our breakdown on why teraflops aren't necessarily the best indicator of performance between the two systems.
