I haven't personally tried it but eye tracking and foveated rendering was highly praised in all the PSVR 2 reviews. They said it does what it promises, and that you don't notice it because the quality adjusts up and down faster than your eye movements.
Though PSVR 2 is wired-only and the eye tracking is only supported on PS5, no way for unforeseen latency issues to crop up like they might here when it's a wireless USB dongle connecting to an unknown PC config
