I've been trawling through my entire catalogue of games that have an unlocked framerate (which didn't perform well but should now increase to 60) so I know which ones to try when the ps5 arrives. Feel free to add to this list. There are quite a few games I didn't realise were unlocked until I went back to them! There are some obscure and older titles I found too. In no particular order:
Murdered soul suspect
Elex
Everyone's gone to the rapture
Until dawn
Arcana gothic 3
Dead island
Dead island riptide
Dying light
Rime
Wreckfest
Telltale games
Saints row 3
Prototype 1
Prototype 2
Infamous second son
Project cars 1 and 2
Borderlands 3
Shenmue 3
Kingdom hearts 3
Kingdom hearts 2.5
Medieval
Nier automata
Sekiro
Dark souls 3
Contrast
Zombie army 4
Dear esther
Dragon quest heroes 1 and 2
Dreams
Little Big planet 3

No doubt there are loads more but these are what I have that I can vouch for.
