Sony's ambitious PS4 backwards compatibility support on the PS5 is going smoothly, SIE boss Jim Ryan says.
Microsoft is the uncontested leader in backwards compatibility, and four generations of Xbox games are playable on the Xbox Series X. But Sony also has big ambitions. Sony plans to support the "overwhelming majority of the PS4's 4,000 games library" on the next-gen PS5, but each game has to be added on a title-to-title basis. Thankfully, progress on this compatibility process is going smoothly.
In a recent interview with CNET, Sony Interactive Entertainment President and CEO Jim Ryan gave a quick update on PS5's backwards compatibility. The console was built with PS4 support in mind, and devs are currently updating their PS4 games to run on PS5.
"We said that the PS5 has been designed to play PS4 games. We're going through the process with the publishers and developers testing that rather exhaustive library of over 4,000 games. We're happy with the progress that's been made," Ryan said.
Sony previously said that PS4 games will be natively boosted on the PS5, complete with improved resolution, higher frame rates, and more.
The next-gen console's new tech is so powerful that some games can't handle this huge boost in performance, so they have to be updated and re-tooled to run on the new system.
"We're expecting backward compatible titles will run at a boosted frequency on PS5 so that they can benefit from higher or more stable frame rates and potentially higher resolutions. We're currently evaluating games on a title-by-title basis to spot any issues that need adjustment from the original software developers," Sony said in a March 2020 update.
"Running PS4 and PS4 Pro titles at boosted frequencies has also added complexity. The boost is truly massive this time around and some game code just can't handle it. Testing has to be done on a title-by-title basis," PlayStation 5 architect Mark Cerny said in the big Road to PS5 presentation.
The PlayStation 5 has two different legacy modes that enable backwards compatibility with older PS4 era games:
- Native Mode - Fully unlocks the Navi GPU at 2.23GHz for next-gen games
- PS4 Pro Legacy Mode - Downscales the GPU to 911MHz, 218GB/sec bandwidth, and 64 ROPs to emulate the PS4 Pro
- PS4 Legacy Mode - Drops the GPU to 800MHz with 176GB/sec bandwidth and 32 ROPs to emulate the base PS4
Sony's PlayStation 5 will release Holiday 2020. No pricing has been announced, and we still don't know how many PS4 games will be playable when it launches.
