You can play most PlayStation 4 games on the PlayStation 5 thanks to the Sony console's excellent backward compatibility feature. But a few publishers allow you to upgrade PS4 games to the PS5 versions for free. This lets you play with 4K dynamic resolution at 60 frames per second and delivers shorter loading times, making for a smoother gaming experience with less waiting around.
The PS5 has been going in and out of stock at retailers since it launched in 2020. The digital-only model costs $400, and the one with a disc drive is $500.
Your game upgrades won't happen automatically or through a typical game update, so it's easy to accidentally keep playing the PS4 version of a game on your new PS5. You have to go to the game page on the PlayStation Network and choose to upgrade to the PS5 version. That'll download the extra data needed for the next-gen features.
You can also upgrade to PS5 versions if you have a physical PS4 game, as long as you bought the PS5 with a disc drive. You'll always need to use the PS4 disc to play the PS5 version; upgrading doesn't get you a free digital copy of the game. You'll still download the PS5 update from the PSN, but you won't need a PS5-specific disc -- your PS4 one will become an authenticator.
If you opted for the digital-only PS5 and have a disc, you're out of luck. There are a few more limitations and caveats:
Some PS5 versions of current PS4 games aren't out yet.
Next-gen versions will be bigger files, so they'll take up more precious memory on the console's SSD.
You'll end up with a fresh list of trophies (each version's list is separate).
A few games' saves won't transfer, and some require you to upload your save manually from the PS4 version before you can access it on PS5.
Some game upgrades are available only in cross-gen bundles or special editions.
However, PlayStation boss Jim Ryan also confirmed that upgrading future first-party games will come at a price.
"Moving forward, PlayStation first-party exclusive cross-gen titles (newly releasing on PS4 & PS5)-both digital and physical*-will offer a $10 digital upgrade option from PS4 to PS5," he wrote a blog post. "This will apply to the next God of War and Gran Turismo 7, and any other exclusive cross-gen PS4 & PS5 title published by Sony Interactive Entertainment."
