Haven't noticed any issues so far, FPS is as expected. Works with vanilla Proton and no launch options just as well, my options are largely for improving the experience on my particular setup.

overall good
sometimes crashes when loading a checkpoint

No major issues, works OOTB
There are 2 codex entries (lore collectibles) that I couldn't read. Luckily they have a QR code so I simply scanned that.
Some information about my setup: I am running Gnome 45.4, on an Nvidia laptop, with the entire xorg session being rendered using the Nvidia card. I also have my laptop hooked up to a second external monitor.
Runs perfectly out of the box with default Proton
Works straight out of the box, even on steamdeck with the default proton version (proton experimental)
Worked out of the box and ran great

audio is noticably crackly. it's more noticable with the music and dialouge. not detrimental enough to the gameplay.
Works Perfectly

Switched Proton versions
Tested Proton versions: 8.0-3, Experimental, GE-Proton8-13
Works great without any major issues on official versions of Proton. When using GE Proton, I've noticed major FPS stutter.
