Played the Demo version offered on the Steam store, which for some reason is causing ProtonDB as not recognizing me as owning it. I played for about 20 minutes, didn't encounter any issues. Ran smoothly at a steady 60FPS. It dipped down to around 45FPS when I was in an area with heavy rain. I also played with a PS5 controller, so I can't comment on Keyboard/Mouse controls. It did seem to utilize the controller's haptics without issue, which is cool. The Options menu also lets you select PS or XBox controller icon scheme.
