Patched the .exe to support 16:10 resolution as described in this thread
In game: set shadows to Low
In steam: Frame Limit: 40Hz, TDP: 8Watts, GPU Clock: 600MHz This significantly reduces the fan noise when playing while improving the battery performance. I haven't played throught every single part of the map, so during some fights/bosses you might need to crank the limits a bit higher.
Game is great on the deck, but by default it does not support 16:10 aspect ratio (black bars at the top and bottom).
To fix this, you need open the .exe in a hex editor (like bless or some of the online ones) and modify every occurence of 398EE33F to CDCCCC3F, as well as change 00001041000050410000804100000000 to 00002041000050410000804100000000, then once that's done you need to install the hud fix from this link and change the new aspect ratio values to 16:10 (default is 32:9). For more info see the reddit post I've mentioned before.

I made some changes to the battery by lowering the FPS to 30fps but decided to revert it back and decided to just have the Steam Deck plugged in all the time instead as I didn't like the drop in frames that I imposed.
Overall I am really enjoying playing this game on my Deck. My main problems with the game are that the battery life of the deck is horrible at only around 1.5 hours max so that means I constantly have my Deck plugged in. Also the graphics aren't as good as I would have liked in this game, but it is servicable and the game itself is still fun.

The game runs flawlessly (although I limited the FPS to 40 on the Deck), except for some cinematics not playing with regular Proton. Make sure to use Proton GE to be able to see them.

"Ultra Wide Screen" with 16:10 ratio --- removes black lines (works well, except menus) External (Russian) language pack --- works well
FPS drop down on default GPU settings

The GPU on this game for some reason stuck at max 1040 mhz wether dock or not, it ruin frame pacing and lower fps with/without FSR, i've tested on other games like kena: bridge of spirit GPU can reach 1600 mhz (max clock) easily. You can change to manual GPU clock and change it to 1200 mhz or 1600 mhz on docked.

I take back what i said, 7.0-6 clearly better with 12.5 low watt usage and around 63 celcius both gpu and cpu
Using proton 7.0-6 only uses 13 watt instead, 8.0-5 and other uses 23 watt.
48-54 fps on open area, but can reach 60 fps easily on more closed area. While other proton can reach 52-58 fps on open area but got 73 CPU and 83 GPU celcius, the fan louder too.

Works out of the box if you want to, but i did lot tinkering for me personally for undervolt testing
I use this game as undervolt test with many benchmarks and from full battery to under 20% for MY LCD steam deck the best setting is -40mv cpu , -40mv gpu , -30mv soc (value can different because silicon lottery)
Jaginness and bit blurriness without FSR
I use this game as undervolt test with many benchmarks and from full battery to under 20% for MY LCD steam deck the best setting is -40mv cpu , -40mv gpu , -30mv soc (value can different each deck because silicon lottery), i also use cryoutilites recommended setting with 4GB UMA VRAM dedicated shared memory instead only 1GB.
After extensive testing on first town on the game with open area and bit crowded also running circle fountain on the game i can confirm GE-Proton8-27 performs better with usage 6.1GB ram and 3.9GB vram with 52-58 FPS on 1280x720 resolution with fill screen and with FSR scale 5 because for me the game got jagginess and bit bluriness ( in general FSR reduce 2-3 fps on any games instead normal resolution but the trade off is worth it), i also test using proton 7.0-6 the game using 6.0GB ram and 3.6GB vram and only got 45-54 FPS.
I tried other undervolt value -30mv cpu, -30mv gpu, -30mv soc the game using 6.1GB ram and 4.1GB vram, even with GE-Proton8-27 the frame dropped to 45-52 my suspect is because vram usage is a bit over dedicated 4GB VRAM, in conclusion GE-Proton8-27 is better in general and using more vram than 7.0-6 means better performance but without my first undervolt value the vram usage is 4.1GB, it can still works but for some reason the FPS dropped significantly.
Graphics settings.
Resolution : 1280x720 with FILL scaling mode and FSR scale 5
Screen mode : fullscreen
Graphics presets : custom
Anti-aliasing : On
Texture filtering : 8x
Shadows : Low
Ambient occlusion : On
Reflections : Off
LOD : Medium
Performance mode : off

Set TDP to 10W
Beat the game, from 0 to ending E (including 98% sidequest completion). Game runs @50-60 FPS, with no noticeable slowdowns. Just set compatibility to force Proton 7.0-6 and use these graphic settings:
- Resolution: 800p (720p if docked)
- Screen mode: fullscreen
- Anti-aliasing: disabled
- Texture filtering: 16x
- Shadows: medium
- Ambient occlusion: enabled
- Reflections: disabled
- Details: high
- Performance mode: on
I personally added FSR at level 3 sharpness too, but the game already looks pretty and plays well with those settings.

This game is definitely playable at good settings on a Steam Deck, but you need to use an older version of Proton
Screen setted at 50Hz and TPD to 8W
Sometimes a dialogue can be a little small, but not a problem
By using Proton-7.0-6 you can get even more performance compared to stock settings; I noticed lower energy consumption and less frame spikes overall. I'm playing at medium/high settings without using performance mode and it runs on a respectable 50fps overall with stable frame times. Definitely enjoyable ad a nice experience with little thinkering overall.

Limited to 8 watts
Never reaches 60fps regardless of settings
Recent Proton update lowered performance significantly, regardless of graphics settings. Set proton version to 7.0.3 in override and performance will be closer to 60fps. Frames never reach 60fps regardless of settings, here are the graphics settings I use which gets average 58 fps with drops to the 40s in dense scenes:
Anti Aliasing off, Texture Filtering 16x (no performance impact), Shadows medium, Ambient Occlusion on, Reflections off, LOD medium, Performance mode on
Peformance also tanks when entering specific locations that cause loading, the tunnel to the beach in the shorefront and the train bridge heading to the junk heap are two, it stabilizes fast and never really happens in combat areas.
Game allows you to set to a 16:10 resolution, but has black bars.
Always slightly below 60fps -- which is not a linux specific issue.
Low shadows, low LOD, 40hz refresh rate.
Dialog font is rather small. Not as much of an issue, as every NPC is voiced in this game. But thought I'd note it here.
The game will hover in the high 40s low 50s for FPS. Turning on dynamic resolution scaling helps but isn't perfect and this introduces frame pacing issues when the resolution changes the resolution. Plus, you know, make it look like a blurry Nintendo Switch game, so I'd rather not use it. Suprisingly the game doesn't feel bad even not meeting 60fps. Not sure what tricks the dev pulled but it's playable and doesn't even seem to stutter sub 60fps even though I know Wayland/Gamescope is forcing v-sync on.
Saw a recent report about capping the frame rate slowing the game down. This is not the case.
The game in it's 1.0 version would speed up if ran higher than 60fps but that isn't even possible in the current patch so this isn't a concern on steam deck. I tested by timing a run from wall to the sea in the fishing village. 60hz/60fps all low settings and dynamic-res enabled and 40hz/40fps, the time was 14 seconds in either refresh rate. If you limit TDP to an extreme that the GPU can't render frames as fast as your refresh rate, that will slow game speed. Set 4 watts and yes 20fps is slow motion. But capping the game to 30fps in 60hz or 40fps in 40hz will not slow the game speed down.
The game is actually really well optimized as far as battery life is concerned. Even with the high setting preset it pulled about 15 watts from the battery and often less. With low shadows, low LOD, everything else default, and at 40hz/fps it was about 12 watts usually. That's 3 hours on a full charge.

NieR Replicant runs great on the Steam Deck, albiet (shockingly) worse than its sequel NieR Automata. The game constantly hits 55-60FPS.
Restrict TDP to 7 Watts.
DO NOT set a custom framerate limit. The game is HARDCODED to run at 60FPS Refresh Rate. Running at a refresh rate lower than 60FPS will cause the game's speed to slow down. This game has a good frameskip implementation and runs about 60FPS anyway.
Before using GE a key cutscene was skipped. GE fixed this.
Played through the whole game. Works great on GE and Deck allows great camera control with trackpad while being able to use analogue stick for top down sections.
Shadows on medium or high will tank the FPS significant amounts but changing to low is fine.
Newer proton version fixed up a lot of the stability problems and have been playing for 10+ hours and haven't seen any issues anymore.
Sometimes waking up during part 1 can speed up all the audio files of the game.
Big slow downs on part 1 of the game.
Have crashed before in part 1
Constantly having fps lowering as the game kept playing. Only fixes if the Steam Deck is restarted.
Sometimes the cutscenes do not want to play visuals but the audios will still work.

I wasn't able to play with stable 60FPS.
I wasn't able to get the game to a constant 60FPS, but the framerate is good enough so it's fun to play. Most graphic settings don't seem to have any effect on the framerate, the only setting that does impact the framerate seems to be the "Shadows" setting. I recommend setting it to Low or Medium. Everything else can be set to Max.
Additionally, the GPU performance level can be set to high, which yields an extra +5 FPS on average: echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level
