Worked great until the end. Just encountered a small performance issue after hours of playing.
After playing for a few hours, the game suddenly felt sluggish with some heavy stutters when initiating the possession mechanism. Not sure what's the cause but restarting the game fixed it the 2 times it happened in my 18 hours playthrough so it was no big deal.

Game runs well. There are some sections with framedrops under 45fps cap, but I was able to play through it all on the Steam Deck!
45 FPS Limit 12 TDP
UI Font can be a little small in some menus.

Works out of the box without any issues and relatively good performance
Everything works including videos. Good performance for a UE5 game, with a RX 7900 GRE got a solid 60fps graphics maxed at 1440p. Some minimal stutter early in the game that I assume was because of shader compilation.

all is good works well

It launches and plays but after a while performance tanks with very bad frame pacing.
After frame rate drops I noticed some artifacts with blood on the ground in combat
After some time frame rate will cut in half and frametimes will spike like crazy

Does not launch
Will not launch on this system. Have tested with Cachy-os native proton, experimental, and the latest GE proton.

Runs perfectly OOB on launch. Great performance.
I didn't have to do anything special, just clicked install and launched it from there. Performs nicely, almost maxing out my 144hz monitor. Minimal shader stutter i assume, but almost unnoticable. Definitely a great experience.

Played with wired xbox controller. Game supports M+KB, just preference for this type of game. No issues at all.
GE-Proton is my default. I didn't try anything else. The game runs flawlessly and I played multiple times with no problems. Enjoy!

Game runs pretty well for the most part, some dips under 45 when you suddenly turn to a busy street but otherwise runs fine. Have not played far enough so there could be issues later down the line.
