The game plays almost perfectly on the Steam Deck! Saves go to the cloud as normal and can be continued to played on PC
I would turn down Shadow Textures to Medium. There are parts of the game that might slow down due to the environment. Nothing to do with Linux but rather the hardware itself. The game plays great and is an enjoyable experience on the Steam Deck LCD at 60Hz. I don't do much testing with Wattage, so unfortunately I cannot give much information on that, but I get about 2 hours on the Steam Deck when playing Tales of Berseria.

Locked 50 FPS, TDP 9 watt
Audio sometimes crackled after resuming from sleep (game still running). After the release of SteamOS 3.5 this never occured again.
I get about 2.5 to 3 hours of battery life using these settings. Game does run stable at 60 FPS with rarely any dips, but capping it at 50 FPS gave me roughly 20 minutes extra battery, without noticably sacrificing anything.

Lowering the TPD down to ~7 helps.
There's occasional audio crackling when waking from sleep, but it's only temporary.
The game runs at a smooth 60 and has some decent battery life without any tweaking

There is noticeable slowdown on boot, but the issue goes away after about 30 minutes. It's smooth as butter from them on

If you have some sound issues change to stereo in game settings.

6-7 watt TDP
Dialogue will not work if on "Surround" setting. Fixed by changing it to "Stereo"
Runs completely fine

In The Empyrean's Throne the game would crash after starting a battle or going further than the very beginning after quick saving and loading that save. Fixed by leaving the dungeon and entering it again. Quick saving in the dungeon again didn't cause any problems.
FPS sometimes dips below 60
Played and finished the entire game on the Steam Deck except for less than 1 hour on my PC.
Despite officially being unsupported on the Steam Deck, the games works great with default settings. Initial estimate on battery life was around 3 hours.
В официальной схеме управления почему-то не работает прокрутка страниц описаний предметов. Исправил так: Настройки управления => Изменить тип устройства: Клавиатура/мышь => Категория: Общие => Описания: следующая страница - назначил сюда L4 (Стандартно стоит клавиша "C", и после изменения визуально ничего не меняется, но начинает работать)
Ранее проходил игру на ПК, поэтому знаю, что почти прошел сюжет на Steam Deck. Не считая небольшого казуса с управлением, ничего не мешает пройти игру, несмотря на статус "неподдерживаемой" в steam.
Reduced TDP limit, but doesn't make much difference
Picture is 16:9. Keep frame rate at 60Hz 60fps. If it's lowered to 40Hz the game slows down. Some minor drops in frame rate, but very enjoyable. Played 13 hours so far on Steam Deck.
capped the framerate in the Steam Deck settings to 60 fps
Works out of the box with capped 60 fps. Despite the fact, that Steam list this game as unsupported, it works just like playing on regular PC.
Game ran at 1/2 speed, had to set the FPS to 60 in the in-game settings, as well as limiting to 60FPS from the SD quick settings.
Tales of Berseria ran very well on my Steam Deck. It kept a locked 60fps for most of my play time on it. I had no issues with it.
Switching from fullscreen -> borderless in-game breaks the game, so I edited the config file.
No issues so far despite being "unsupported" on Steam.

Despite the "Unsupported" statut from Valve, everything seems fine and runs like native. Played several hours without getting any issues. Performance are great and videos are fine.
