Sony earlier confirmed that it will push an update for the PlayStation 5 this week, with the main change bringing the long-awaited variable update rate (VRR) to many players. After adding this feature that was available on the Xbox Series X/S since its launch, it can reduce input lag and screen tearing when the PS5 is running the game. Of course, in the hardware part, you also need to have a TV and monitor with HDMI 2.1 that is compatible with this feature. Currently “Marvel’s Spider-Man: Miles Morales”, “Ratchet & Clank Rift Apart”, “Ghost 8: Village” “(Resident Evil Village) and other works have been determined to receive relevant optimization updates, and the variable update rate will be automatically turned on after entering the game after the upgrade.
Over time, more titles will support this feature in the future. And Sony also said that you can turn on the variable update rate option for any game, but the specific effect and whether it will cause problems may depend on the software itself, display device, settings and other factors.
