The handwritten notes are sometimes impossible to read on 800p, but you can easily read them when pressing A and showing them in larger and an easier font.
Using the low graphics preset with AMD FSR 3 Quality and FSR 3 Frame Generation it's actually a nice experience now. When limiting the FPS to 30 in the game settings, I get the most fluent experience at 40-55 FPS. Do not limit the display refresh rate in the steam performance settings below 60 Hz as it causes significant input lag in combination with Frame Generation. Battery will last you about 90m.

Runs reasonably well given the hardware, and with no Proton related bugs that I could see.
Used balanced XeSS at 800p, and the medium preset, with shadows set to low. Game looks quite beautiful on Deck; despite the slightly soft image. Performance hovers mostly around the 30fps mark; with some areas dipping below 25fps. Overall I still felt it fine to play regardless.
Noticed zero Proton related issues; everything felt as it should.

Fantastic game. Terribly optimized. 30 fps avg with dips into the 20s, even on low/potato and/or lowering resolution.
Class ability text is small, otherwise fine.
The game struggles to hold 30 fps. Lowering the resolution and/or graphics to low/potato keeps it closer to an average of 30, but will still dip into the 20s.
I listed as not recommended due to the performance, but the game is so good and mostly playable as is that I'd recommend it to fans of the first game or those that only have steamdeck. Hopefully future optimization patches make it a masterpiece. NOTE - users reporting inflated "stable fps" numbers are incorrect. This game has a bug where if v-sync is turned on, gamescope will report your device's refresh rate. 40/45 refresh rate is an unplayable stuttery mess. Turn off v-sync for accurate numbers.
Steamdeck performance tab settings. Uncapped frame rate, 60 hz refresh, linear upscaling. Everything else OFF.
In game settings. FULL SCREEN, 1152 x 720, motion blur ON, framerate 30 fps. Intel XeSS Upscaler @ Quality. Graphics preset: LOW. Detailed shadows OFF.
This will give you 30 fps most of the time while preserving the games visuals. Will dip in certain areas, but didn't effect my enjoyment. Putting shadows on potato mode will help further, but the game looks real weird without them.

Class ability description text is a bit small, otherwise fine.
For stable fps, you need to either run the game on potato quality for 1280x800, or lower the resolution to 1152x720 or 960x600 and use the Intel XeSS upscaler with low settings. On potato quality, shadows are turned off which completely changes the look & tone of the game.
Need to sacrifice nearly all graphical fidelity to achieve 30 fps. Still dips into the 20s fairly frequently.
Other reports stating stable 40/45 fps aren't correct. This game has a bug with gamescope, if in-game v-sync is on, gamescope will report whatever your refresh rate is as the fps. Locking the game at 30 or 60 fps and setting a 40 or 45 refresh rate in deck settings is a stuttery disaster. Disabling in-game v-sync will report proper numbers.
Leave steamdeck settings default. Frame rate uncapped, refresh rate 60, linear scaling, everything else off.
In game settings: Full screen, 1152x720, motion blur ON, VSync OFF, framerate 30 fps, Upscaler Intel XeSS, Upscaler Quality QUALITY, graphics preset LOW, detailed shadows OFF
Going to 960x600 blurs text to the point it's unreadable, but it does fill the screen.
- Alternatively you can keep the game at 1280x800 and use graphics preset POTATO. Losing the shadows is a huge hit graphically, though, and none of the other options change much performance wise. Use this if the slightly blurred text from the lower resolutions drives you insane.
Hopefully a real optimization patch can help this games performance down the line, but it's playable right now and the game is enjoyable enough to compromise graphically.

Currently the performance is too sloppy/inconsistent to play this game at a stable framerate.
Proton Experimental + Proton 7.0-6
Performance dipped hard in Yaesha down to 12fps, even when trying with and without any upscalers.

Performance is too inconsistent at this time. Upscaling being required makes the game look awful with FSR. 50-60 FPS is not hapening.
Tested both AMD FSR and Intel XeSS. Both have dips under 30 FPS in certain areas though XeSS does look better.
All low settings
Some small text is blurry due to upscaling
Upscaling artifacts
corrupted saves still hapen though rarely
Upscaling is required and on all lowest settings. Still dips under 30
crashed 3 times so far

DO NOT USE FSR - Use the Intel upscaling algo, I went from 25fps and heavy artifacting with FSR, to 50-60 FPS and considerably improved graphics with the intel upscaler. It's incredible what a difference it makes.
Only when FSR enabled. Vastly improved with intel XeSS
XeSS on performance or even balanced mode runs a lot smoother than FSR on performance mode, and it looks far better to boot.

Heavy artifacting due to the need for amd fsr ultra performance
Everything on low, 1280*800, AMD FSR Ultra Performance, still felt a bit unsmooth but playable.
Launching with the default configuration lead to an error about missing prerequisites amd the game closing afterwards. Proton Experimental fixed this.

Graphics preset: Low Framerate Cap: 30 fps Average Playtime: 2-3 hours
Some text can be small or difficult to read.
Particle Effects are frequently artifacting
Hardware throttled on Steam Deck
Tested on pre-release game version
