Since Day 1 on the PS5 I've had Performance Mode set as the default. Platinumed Astro's, finished 100% Miles in 60fps, and finished Immortals: Fenyx Rising in Performance. Also played about 2/3rds of the Dirt 5 campaign in the 60 mode (the game becomes a grind, play Wreckfest instead). On the XSX side it's likewise been entirely Performance mode, and now with the FPS boost I'm revisiting things I skipped last gen like Prey (which is amazing). I'm not even going to bring up the PC where everything I run is at 120+ fps.
But earlier this month when Sony gave out the 2014 Ratchet and Clank I figured I'd load it up and finally finish/platinum it before the PS5 game comes out in June...and it felt like a slog at 30fps. After being spoiled by next-gen and almost everything (looking at you Watch_Dogs: Legion) having a 60fps option, it's just not easy going back to 30fps gaming.
