Extensive testing has confirmed the existence of a persistent PS5 stutter issue when making use of the console's variable refresh rate option. The problem is only going to be apparent to players using high-end TVs that offer VRR support in the first place, but those are the most demanding gamers in Sony's audience – and they've been begging for a fix for months.
Typically, TVs and monitors run at 60Hz, so if a game runs at 60fps, you're getting exactly one new frame every time the screen refreshes – or exactly one frame for every two refreshes if the game's running at 30fps. If a game deviates from that target frame rate, it can start to look choppy and stuttery on a traditional 60Hz display. (See: most FromSoftware games.)
