No issues, stable performance
When using FN/ superkey the keyboard wasn't accessible anymore.

Works without a hitch
Works perfectly out of the box without any tinkering here (I set the default proton to experimental), only issue i noticed was that the keybinding did not allow me to bind anything to the 7 key, the game would usually set the mount to that key, so I had to rebind it to 8 instead.

If you have gamemode installed you need to add the following command or the launcher will be just a black window gamemoderun %command% --disable-gpu
If you don't have gamemode installed you need to add the following command for the same reason %command% --disable-gpu

gamemoderun %command% --disable-gpu
Cryptic Launcher updates seem to break Proton compatibility, making the launcher window appear completely black, but adding --disable-gpu fixes this.

Disable on-demand patching in launcher. Restart Launcher for first time setup.
Was able to connect to servers and play without issues.
Disable on-demand patching in launcher, then restart launcher after disabling to fully patch. Use Alt-tab to force close via Steam to exit the application.

disable " on demand patching"
slow loading some time
don't forget to turn off " on demand patching " in the launcher option and don't forget to personalize the in game graphical settings

just make sure that you have enough storage for the patches (around 30GB?) check the install location in your steamdeck
a bit of learning curve in the mapping of keyboard controls to controller
Disable on-demand patching in launcher, wait an hour for patching after each update, and Alt-tab and force close via Steam and you're fine.

First off, I had to disable "On-demand patching" to get it to run relatively smoothly the first time around. Subsequent patches after weekly updates still run into a lot of pausing, but at least the first time around was smoother. Beyond that, downloads as a whole were slow. I have a gigabit connection and it took 3 hours to download the nearly 30GB of game files. My friend on Windows downloaded it all in no time, so it's clearly an incompatibility with Wine/Proton. Once ingame, it's fine, though. I was getting 375 FPS on my RX 6700 and had to manually limit the FPS before entering or else the performance alone would make it hard to Alt-tab out and use other apps. Once that was stabilized, I could properly limit the FPS ingame, but I'm leaving the environment variable anyway just in case.
The game consistently freezes on exit. No progress gets lost from it, near as I can tell, but it's still annoying to have to go over to Steam and click the Stop button to actually close the game.
There was a minor issue where my friend and I would see chat logs of the other disconnecting and reconnecting, but I'm not sure if that's an issue with Wine or if it happens across Windows clients too. There's no tangible lag when it happens, so it seems a nonissue in the end.
Without these tinkering steps and the knowledge that the launcher can potentially freeze, that alone can easily drive people away. However, once aware of all that, it can be as fun as any F2P MMO can be.
My launch arguments are because I use a dual GPU setup with a GTX 1050 as the secondary GPU for recording/streaming encoding purposes. The game detected both GPUs but defaulted to the 1050 and refused to let me change away from it for some reason, so I just made Linux hide it via the environment variable. None of my launch arguments are actually important for most people. The game can be run without issue on most setups without tinkering with them.
A lot of tinkering to get it to launch and still unable to get pass initial setup.
Could not get it to launch on Experimental. Forced 6.3-8 to get it to launch. During initial setup after launch, it's stuck patching 15 files and never gets passed it. Left it for several hours with no avail.
Other than using forced older version of proton ( proton 5.13-6 ) and putting fps at 30 so far there have been no other problems playing the game
Over all with miner tinkering to proton and frame rate game plays fine so far haven't looked into controller settings I used keyboard and mouse if there isn't a compatible controller template it would be great if one was made that works with the steam deck controls to save on needing to use the keyboard and mouse. 👍🏻

Capped at 7 watts and 40 fps
Neverwinter runs amazingly well on the Steam Deck. It allows you to scale the UI perfectly in the game's settings to make it look just right on the Deck's screen. The Steam Deck is fully capable of pushing 60 FPS on max settings. This will get you around 1.45 hours of battery life. If you cap the framerate to 40 FPS and the TDP to 7 watts, you can extend this to over 3 hours. I did test capping to 7 watts and having the full 60 FPS. This is again smooth, but lowers battery life to 2 hours. So 40 FPS is really needed if you're trying to maximize battery. The only downside with this game is that it doesn't natively support a controller on PC. So you will need to either create a steam input profile or use a community profile. Other than that it's flawless.
Funcional, estou usando o Proton GE para usar o FSR, joguei um pouco usando o Proton experimental e não tive problemas.
Funciona perfeitamente, sem problemas

With a quick change in the control scheme the experience was incredibly easy to setup and enjoyable on the Steam Deck.
Small amounts of culling getting confused when moving from different areas but was almost unnoticeable and didn't effect gameplay at all.

excellent game, running flawlessly
just run out of the box

occasional crashes to the desktop
around 20 fps loss give or take
no problems so far
go ahead runs great
Playable
All good
during character creation cutscene game dropped to login menu, went smoothly after
As if native app. I switched from 'experimental' to 'default' (7.0-1) and it seemed to go smoother. The launcher was fine. Check all boxes except 'forced verify'. (Was slow to download and install before, but launcher worked great with 7.0-1. Not sure if that is because the installer was done before i tried the 7.)
Works OOTB (Proton 7.0-1)
The biggest 'issue' getting this game to run is the jankiness (regardless of platform) of the game's launcher/installer. Setting proxy to EU for the first download, and leaving it in foreground for the entire process got me through it (after a couple of stalled attempts). I've had similar problems on windows in the past, so this seems to be a cryptic launcher issue rather than a Linux/Proton one. Once installed the game launches and works without problems.
No issues at all
This was OOTB on Proton 6.3-8 for me.
Like others here, I disabled "On Demand Patching" in the launcher options. I have apparently been lucky, in that I did not experience issues with needing to delete the gameprefs file between sessions of play. I will update my report if I experience that (or any other) issue.
Once running it works flawlessly so far. Hopefully there will be a fix for the gameprefs issue. Something to work into Lutris maybe
As with the previous report I could only launch once before getting a black screen after the launcher. To fix I had to delete the gameprefs.pref file each time I wanted to play the game, where it would then be created again. This meant I either had to manually change all my setting each time I launched the game or have a corrected copy saved and copy paste the setting across.
Game ran once and wouldn't run again until I deteted the Gameprefs.Pref file in the /live/localdata. I also turn off "on demand patching" and turn on the "Force Verify" in options in the launcher.

Individual key-presses were laggy at best, ignored a significant portion of the time.
performance would vary wildly. Graphics were clear (so, likely not a GPU issue) but keyboard and mouse input would often go undetected. It got to the point where I would try to walk in one direction and would often keep walking way past when I tried to walk a different direction or jump. In addition to key presses being late or not registering at all, mouse input on buttons would often take 2-3 clicks to register. The mouse issues started as early as the perfectworld launch screen.
Crashed once, but within first 15 min.
I haven't found any issue using proton experimental. Well done!
Disable on demand patching through the launcher options
I don't know why I see a layout of a controller but as a player which never played this game I had a hard time to figure out how to play.
For some reason the game thinks that I'm on a controller. 'e' is named 'LT' 'r' is named 'RT' the key 'f' doesn't display at all and more unclear buttons that you don't know what are they doing. You need to to turn off "on-demand/dynamic download" so you won't stuck on infinite loading screen.
Works flawlessly and runs always at 60fps even with maximum settings. Also the mouse lag issue I had a year ago is now absent.
As mentioned in previous reports, I disabled "conditional patching" in the launcher settings.
The game installed and run. Problem with mouse fixed with previous version of proton (4.2-9)
After the first patching (took a while) I had no problem. The only issue I had was with the mouse. Left and right clicks not responding. I run it with a previous version of proton (4.2-9) and this problem fixed.
Platinum. Install and Play.
If you are stuck in loading screen, disable on-demand/dynamic download in the launcher, and restart the launcher.

Make sure to use the newest version of Proton!
The game booted, installed, started, andran perfectly fine with Proton Experimental and the launch options, "RADV_PERFTEST=aco PROTON_NO_ESYNC=1". I was following an older guide, and looking at other posts here, on playing the game in Proton, they said to use Proton-4.2-9, but that was causing those mouse lag issues people here were reporting a year ago. I spent many hours slamming my head into my table trying to change my mouse polling rate on my install of MX Linux(I don't think it's possible), I then decided to try the newest version of Proton to see what would happen, and it worked! The mouse lag was gone, and the game runs just as well as it did before I switched to Linux!

The game launcher starts, the game downloads. Then I can start the game, but it hangs at the loading screen.
Might not be a Linux / Proton problem. Either way, nothing I did solved the issue => unplayable (for me)
Used the following launch commands: PROTON_NO_ESYNC=1 RADV_PERFTEST=aco prime-run %command% (the prime-run command is because I don't use my nvidia GPU for regular graphics on my laptop and it's needed to turn it on, will most likely not be necessary in other setups)
