Everyone's different, and you can get used to a lot.

So some people might not be able to tell 90fps from 120fps, but I definitely notice. But if I played something at 90 for long enough, I'd get used to it and stop noticing how much worse it was from 120 fps.

I will say they don't get near enough credit for not only adaptive triggers, but them working on damn near any game that appears on PlayStation even while on PC.

I bought a ps5 just for those triggers, and gave it away (but kept a controller) once it worked on PC.

That's the direction Playstation needs to go. If they made a new controller with Hall Effect sticks and 4 back buttons they'd absolutely clean up. They came so close with the edge, but didn't give a back button for half the face buttons. And went "replaceable" sticks that will eventually break instead of Hall Effect.
