Sony is trying to clear the confusion around the PlayStation 5’s backwards compatibility mode, and says the console will be able to run the “overwhelming majority” of all 4,000 PS4 titles 

On Friday, the company issued the clarification after Sony system architect Mark Cerny briefly mentioned the software testing challenges surrounding the PlayStation 5’s backwards compatibility with older PS4 games. 

In a presentation two days ago, Cerny indicated that the next-generation console wouldn’t necessarily be compatible with all PS4 titles. The problem is the increased processing power on the PS5. “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,” he said.

Cerny went on to add that Sony has been testing the 100 most popular PlayStation 4 titles on the upcoming hardware. “We’re expecting almost all of them to be playable at launch on PlayStation 5,” he said. 

However, 100 games comprises only a small slice of the PS4’s full game library. So some gamers were baffled at Cerny’s language during the presentation. 

In response, Sony is trying to reassure consumers about the PS5’s backwards compatibility feature. “With all of the amazing games in PS4’s catalog, we’ve devoted significant efforts to enable our fans to play their favorites on PS5. We believe that the overwhelming majority of the 4,000+ PS4 titles will be playable on PS5,” the company said in an updated blog post

According to Sony, the company has actually tested “hundreds” of PS4 titles on the new hardware, and is preparing to test “thousands more” as it prepares to launch the PS5 this holiday season. 

In another piece of good news, Sony says the increased computing power on the PS5 will be able to run PS4 titles at “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,” the company added.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
