It works very well, but it needs some adjustments for the FMVs to play without audio issues.

Audio issues in the FMVs
The game runs and works well with this version of GE-Proton and the following launch parameters. It was not necessary to convert the videos for the cutscenes to play correctly.

In order to play this game on the Steam Deck you must transcode the video files the game uses from ASF Video in an .WMV container to .MP4 in a .WMV container and you must use the GE-Proton variant. Official proton will not work properly and won't play cutscene files.

Играл с TDP 9W, все стабильно и время игры достаточно продолжительное
Установил русификатор по единственному руководству в Steam и все отлично. Игра идёт стабильно, никаких багов и проблем. Даже не поймал проблему с кат-сценами

A Proton update partially fixed the issue with FMV cutscenes being borked. They were flipped, had audio issues, and awful performance and now they just sound and perform awful. I've seen reports that some people still have flipped FMVs, but that hasn't been my experience. These are for if your FMV's are not flipped.
I uploaded the fixed FMV files on nexus here: https://www.nexusmods.com/devilmaycryhdcollection/mods/242
Other people here have uploaded the prompt I used to re-encode the FMV's.
only in FMV's
FMV's stuttering and low quality

So far I have only tried getting the cutscenes/videos working properly. I will update my review after I complete all three of the games.
Using the fixes mentioned here previously did not fix all the issues, unfortunately. While the game no longer had flipped or missing videos, their quality was still a mess.
Then I tried GE-Proton (version 9-25 to be exact) and, luckily, it fixed the audio issues. The problem now was that the flipped videos were also fixed from the Proton side and I had the videos flipped again (from Nexus Mods).
To fix this, I edited the provided shell script to remove the part that flips the video (delete -vf vflip
). I have uploaded the non-flipped encoded videos to a cloud storage. So, if you don't want to go through the encoding process yourself you can download them here:

All you need to do is extract the archive and put the "data" folder into the game's directory.
Without any tinkering, the audio of most pre-rendered videos crackled almost all the time.
On some older Proton versions, the pre-rendered videos are flipped upside-down.

DMC1 plays great docked or handheld with fix mod and Proton 8.0-5. Will update when I test others.
As noted in other reports, cutscenes are either upside down or skipped on the Deck without mods. Need to download the fix mod, and ensure you're running the game on Proton 8.0-5 to fix this.
Will update when I test 3 (2 is bad so I'm not gonna bother replaying it). 1 works great in handheld or docked after fixes have been applied.

Used this mod to run a script in each game's video folder: https://www.nexusmods.com/devilmaycryhdcollection/mods/51
Without the mod, cutscenes were slowed down and had terrible cracking.
When switching games, it would exit fullscreen. Although it would revert after about two seconds.

Cutscenes had poor audio and some slowdown/timing issues, so I used the link provided by others for cutscenes that are reencoded for linux and steam deck users https://www.nexusmods.com/devilmaycryhdcollection/mods/51 this is a simple drag and drop solution
I am nearly through the first DMC game and I can report that there are no issues in it. I have not encountered any crashes or errors in it.

only in fmv cutsceens
fmv cutscenes are slightly degraded
had to restart steam deck after playing game docked with XBOX Series X controller to be able to play the game on steam deck in handheld mode
Steam Cloud saving feature does not work from Steam Deck to my PC

None
No audio issues, no graphical issues, no saving issues, nothing the game works completely fine oddly enough especially with the issues other people have been having with it for awhile all inputs work just fine the text is easily readable in game and the game plays and runs perfectly.

FMVs had audio issues. Using the mod at https://www.nexusmods.com/devilmaycryhdcollection/mods/51 fixed the audio but mirrored the image. Switching Proton version to the regular 8.0-5 fixed that part.

FMVs flipped, audio degradation
Tried this on the original Steam Deck a long time ago and wasn't satisified with the FMVs not functioning. Now the game looks and runs fantastic on an OLED deck, but as other reviews stated, the Nexus mod is definitive for fixing the audio. As of writing this, the videos will remain flipped unless you enable Proton 8.0-5 for compatibility. Once you replace the videos and enable Proton, it's gold.
Despite the reports about the cutscenes being fixed with a recent update, I was still getting upside down videos and green screens/no cutscenes/skips after 2 seconds on other versions of proton. Said fix is kind of a pain to get in the first place because it's distributed as 1GB+ shader cache update and there's no easy way to trigger a cache update for a single game, so you either wait for Steam to feel like downloading it or you enable and disable the cache in Steam settings under desktop mode which forces a global cache redownload on ALL your installed games.
Ultimately what fixed the cutscenes for good for me was downloading the reencoded videos from here : https://www.nexusmods.com/devilmaycryhdcollection/mods/51
As a bonus, they also have higher quality audio compared to Steam's "fixed" files. I can confirm that with this and default Proton cutscenes play normally in DMC1 and 3. Do note that if you install these files before the shader cache update they may get overwritten by Steam's later and you may have to re-apply them.
As for saving, I can confirm cloud saving is not enabled for this game but personally did not experience any issues or data loss when testing a couple levels in both DMC1 and 3, I was able to save and resume my game normally even after exiting the game or restarting the Deck. It is worth noting than this is on a fresh install, I did not have any saved games from previous installs.

This game is nearly perfect but I can't recommend it until the save bug gets patched. You have to sit through the whole game in one session
Seems like the cutscenes audio starts to crackle at least in DMC 3
Saving works perfectly on windows however if you try to save on the steam deck it just doesn't work
Overall, would love to recommend this but without saving its not worth it. You might want to try playing through an emulator instead
Game has cutscenes bug on steam deck they are fixed thier for it once done fine ver of game

Cloud saves aren't supported
At this point in time these games work perfect out the box on the steam deck. I also went out of my way to install ddmk and that works too if you change the launch options and download downgraded executables.

The Game used to be broken and had cutscene issues, crasing and upside down etc etc, but it just seems to work now.
Nothing to add, just installed using the default proton selected by valve and all three games worked perfectly fine, playable from start to finish for better or worse(DMC2)

FMVs use a low quality audio codec
Not sure if working as intended, but although the game allows you to manually save your progress, it will only save it to your current mission. When you load, you will start from the mission beginning (and not from where you had advanced if you did, for example), with all red/blue gems that you had found (if any), with the yellow gems spent (if any) and no monsters dead (if you killed any).
(Please note that this is for DMC1 only, as it's the first game of this collection and the one that I tried first)
The game's FMVs are no longer flipped vertically and can now be watched without having to enable any Proton (be it GE, Experimental or 8.0.3+). In fact, doing so will cause a green screen when an FMV is supposed to be played and after a few seconds it will be skipped. Click on "delete proton files" if this happened to you and just play the game normally with no tinkering. DO NOT use the ffmpeg mod/workaround.
The game's Anisotropic Filtering is limited to 4x. This means that any walls and ground will look blurry when viewed at an angle. You can go (in desktop mode) to the directory where dmc1.exe is and create a text file (rename it to dxvk.conf), include a line in it called "d3d11.samplerAnisotropy = 16" (without the quotes) and the textures will look a lot sharper, as it will force AF 16x with no performance loss.
I'm so far at Mission 6 and the game hasn't crashed once. I saw a comment stating that it starts crashing on Mission 14, but it could be outdated.

Cutscenes had to be (converted to fix shortening and mirroring)[https://steamlists.com/devil-may-cry-hd-collection-how-to-fix-fmv-cutscenes-on-your-steam-deck-linux/]
I had a great experience (docked) with DMC3 after patching the cutscenes (https://steamlists.com/devil-may-cry-hd-collection-how-to-fix-fmv-cutscenes-on-your-steam-deck-linux/). Supposedly, the latest update has this patch built-in, so it should become playable/verified soon.

Cutscenes sounds a little distortion
After today's update, cutscenes works like charm!

While you can play the game(s) perfectly fine, the green screen on the shortened FMVs (at least with DMC1) make it confusing and annoying.
Changed the resolution to 720p
Green screen during FMVs, FMVs only last for a quick second

Use official proton 8.0-2, cutscenes got green screen
I tried use official proton 8.0-2, the text problem fixed, but cutscene still got green output. An I've also tried GE-proton 8-6, the cutscenes plays but only play about 3-5 seconds...

Game runs perfectly fine, and it seems that Valve has included cutscenes in the shader cache so there is no mirroring anymore.

Latest version does not require the video transcode and binary patch. Game runs great out of the box.
You might want to set resolution to 720p thouhg (default sets 1080p).
cutscenes seem to play mirrored...
expect mirrored cutscenes, i did not encounter any problems

Aside from pre-rendered cutscenes won't play correctly, all gameplay can be considered as no issue
Some (not all) in-game diaglogs are missing / crackling / low in voice volume
All pre-rendered cutscene were up-side-down (mirrored??). But skipped itself after 1-2 sec of playing
Tried all DMC 1-3. Report based upon first mission completion, reached the very first intermission save point.
Cutscene videos don't play. You may not notice this because the game will run normally but they will actually be skipped.

las cinematicas se cortan o aparecen inversas en dmc 1
el juego funciona fluido pero en las cinematicas se cortan o aparecen al reves
- 60 FPS (don't play DMC with less then 60fps imho)
- 60 Hz
- Half rate shading
- TDP 10 Watt (you probably could go lower)
- FSR 4
- Inital cut scence are buggy (mirrowd, auto skip)
- later on it seams to be fine (played only 2h)
- I only tested DMC3
You can watch the first cut scens in youtube.
Half Rate Shading Thermal Power (TDP) Limit: 9 Watts Scaling Filter: FSR Sharpness 5
Do no lower the refresh rate, the games were designed with 60 FPS in mind.
Given that one of DMC's biggest boons is it's presentation of it's story, it's hard to recommend when half of the cutscenes just won't play.
XBox controller would violently rumble for a long time for seemingly no reason
Cutscenes and most video files that need to play simply won't. Any time a black screen is shown, typically pressing start once or a couple of times is enough to skip the cutscene and get back to play or the menus
The popular mod, DDMK doesn't seem compatible with trying this on Linux at all. That alone is enough to recommend staying away entirely, unfortunately. Not being able to change resolutions, visuals, and many other things sucks
While FMVs do not show, you can hear their audio but they are extremely distorted. In-game audio also has some minor crackling.
FMVs do not show.
A lot of framepacing issues. Otherwise framerate is solid 60fps.
This report was made with very limited play time on Steam Deck, playing only Devil May Cry and Devil May Cry 3.
The games get to the 'loading data' screen shortly before their crash.
