Steam Deck: Hogwarts Legacy performance settings and benchmarks

Yes, Hogwarts Legacy runs great on your little buddy, the Steam Deck!
But of course, it's never perfect. Are you looking for some performance improvements? You can try adding the options below.
Open desktop mode (or use ssh/scp), open Dolphin/file explorer and edit the following file:

/home/deck/.local/share/Steam/steamapps/compatdata/990080/pfx/drive_c/users/steamuser/AppData/Local/Hogwarts Legacy/Saved/Config/WindowsNoEditor/Engine.ini

nano "/home/deck/.local/share/Steam/steamapps/compatdata/990080/pfx/drive_c/users/steamuser/AppData/Local/Hogwarts Legacy/Saved/Config/WindowsNoEditor/Engine.ini"

Go to the end of the file and add the following lines:

[SystemSettings]
r.TemporalAACurrentFrameWeight=0.2 
r.TemporalAASamples=4 // use 8, 16, 32
r.Tonemapper.Sharpen=0.8 // something between 0.5 and 1.0 

Save the file and try to play Hogwarts Legacy again.
On my end, this gives me a steady 60fps using the default Proton version.
