I would recommend a 45 FPS cap with 90Hz for the OLED Deck because the game wont reach 90 FPS (Maximum I've seen is ~75 FPS) despite very low CPU and GPU usage.
3 Watt TDP provides 45 FPS but frame times can be inconsistent. 4 Watt TDP provides a smooth 45 FPS but can drop occasionally in scene transitions or heavy screen effects. 5 Watt TDP provides a smooth 45 FPS with little to no frame drops in my 12 hours of play.

Since the game supports moues i turned my trackpad to mouse simulation
The changes i made to the controls were only to feel more comfortable
Spiel läuft 1a, Cloudsave ebenso. Nur Verknüpfung mit Nintendo Switch nicht direkt am Deck möglich.
Beim Verbinden des Nintendo Switch Accounts öffnet sich zwar das Login-Fenster, jedoch ohne Inhalt. Daher muss dieser Schritt auf einem anderen Gerät wie PC, erledigt werden.
Verknüpfung mit Nintendo Switch Account nicht direkt am Deck und nicht im Desktop Modus möglich. Ich musste es am PC erledigen.

All settings at their lowest. A potatoe could run the game.
No more fps drop issue since the last update. Game runs just fine. Great experience.
The game is playable, but the memory leak issue affecting fps is still rather disruptive.
The game drops fps after about an hour of play time. It is consistent enough to be disruptive. A simple restart of the game fixes this issue, but at this current point and time, it has not been addressed.
Applied Proton Experimental to the game in hopes of fixing the memory leak issue, but it did not solve the problem either way. Until the issue is resolved, just remember to refresh once the drop in fps hits.

After resume from long time suspend, audio is broken
set fullscreen on first start, the game crash even if the setting is applied but still appear disabled
Due to a memory leak the game slow down massively after ~30 min, reboot game needed in this case
Suggested even with mentioned problems
As long as you don't care about saving and rebooting the game each hour, the game is perfectly playable
Fps Cap to 40
After like an hour of gameplay, framerate drops to 14-15 until i reboot the game.
Runs fine at 40-50fps, but after a random period of time it drops suddenly to 14fps until you relaunch the game.
Sometimes you get 2min other times you get 15min, but it always happens.

Playable in short bursts, requires restarting each time it slows down. Otherwise completely functional.
Framerate limited to 30fps, Half Rate Shading enabled, Scaling set to Nearest
enabling fullscreen requires a restart, but after re-opening the game the setting is still disabled.
fps drops to 14 and controls get significantly delayed after about 30 minutes of play. Resolved through restarting the game, but issue always comes back about 30 minutes later.
The game is good but the constant slowdowns and performance issues makes anyone not amazingly patient rip their hair out in frustration.
Every time I select fullscreen the game shuts down and unticked is when starting again, rinse and repeat.
The games framerate is all over the place between 15- 50 fps, however after playing for a certain amount of times and swapping zone will it suddenly run even worse with massive input Lagg and everything running in slowmotion, saving and rebooting the game makes it run playable again.
Massive slowdowns in performance.
The game is steamdeck verified. It boots with zero configuration. It got smooth controls and works out of the box, but the game in my opinion isn't considered playable as you need to constantly reboot to have a somewhat decent performance in the game.
Weird random framedrops into the 40s. Doesn't feel smooth.
When you boot up the game for the first time, you have to activate fullscreen in settings, the first time you do this the game will close, but once you boot up again it will stay in fullscreen with no more issues.
Game seems to run at around 47-50 fps on GE-Proton7-14
Game runs as expected outside of the lock at 50 fps. Not a big deal since the game is turn-based anyways.
Works great out of the box with GE - not tried the default proton version myself. Some settings require a reboot but nothing strange.
Game initially boots in windowed mode with black bars. Enabling full screen tries to reboot but the game just crashes and you have to boot it again yourself. There is also a scaling option that when you increase or decrease does not fill the screen properly (either bleeds outside of the viewable area or the game appears smaller on screen), but a reboot fixes this issues as well.
Lower than expected FPS (under 50), some stuttering
Slowdown during some animations (character emotions?)
crash after about 5 minutes with every version of Proton I was able to launch with 7.0-1, GE7-9, 6.3-8, would not launch with 5.0-10, 6.21GE-2
Only tested in SteamOS mode, as that's my primary use case for Steam Deck. May try other Proton versions and update later, or will test again when the devs fix issues on Windows as well.
