Super playable after fixing annoyances and major issues, recommend playing on a controller, runs exceptionally well and stable (8GB+ VRAM)
Potential fix for startup hangs: Edit the file ~/.local/share/Steam/steamapps/compatdata/812140/pfx/drive_c/users/steamuser/AppData/Local/Ubisoft Game Launcher/settings.yaml and set overlay.enabled to false, this also get rids of the annoying ubisoft overlays for "This hardware is not supported". Deleting the intro videos folder per other comments is a nice QOL too. Not sure how much disabling steam overlay also helped, but it's consistently booting without issues lately.
Problems with the mouse not being grabbed seems like a Wayland only thing to me (I couldn't reproduce them xorg), at least for NVIDIA. Even fullscreen or windowed mode occasionally opens with artifacts or broken parts here on Wayland. Got a dualsense and swapped to controller only ingame, perfectly playable otherwise.
Had to swap my mouse polling rate to 500 Hz instead of 1000 Hz as it sometimes got stuttery, laggy at random (alt+tab and back, loading a save). Seems to happen more on Wayland than Xorg, but I'm playing on a controler now and it's been perfect.
Two crashes so far inside cutscenes in 40h of gameplay. Not really a problem as restarting the game is fast on a SSD and loads quite close to where you were.
Runs perfect with minor changes, most notably disabling FSYNC and lowering shadows to Medium solved all performance issues
PROTON_NO_ESYNC=0 PROTON_NO_FSYNC=1 %command%
I traced down performance issues on my system in a couple dxvk/vkd3d games to fsync, I had to either launch steam with
PROTON_NO_FSYNC=1 steam-runtime/steam-nativeor on game launch optionsPROTON_NO_FSYNC=1 %command%(better first option or set on ~/.profile asexport PROTON_NO_FSYNC=1).This should make it use ESYNC, so make sure your system is properly configured https://github.com/lutris/docs/blob/master/HowToEsync.md
This might alternatively be solved with changing the kernel to some other with better fsync related patches, default kernel doesn't do it for me. Wish I had solved performance before finishing the game ! Totally playable on Linux.
