I can't compare against Windows but it seems equivalent - I get 60 fps everywhere except cities where it lost 5-15 fps.
LD_BIND_NOW=1 gamemoderun %command%
I had one or two instances of it locking up at the Vocation Guild in Vernworth - worked around by using gamescope for a while.
I tried the suggestions on Arch's Wiki page for "Gaming", the difference maker for performance as far as I can tell was making sure the kernel had Multi-Gen Least Recently Used enabled. With that off I had large swings from 60 to ~20 fps, now it's mostly locked 60 fps with the same settings in game.
Temporarily tried using schedtool -F
but that made performance highly variable again, and made things unstable.

Slightly grainy textures
Game hard-locked up setting vocation guild points.
It works and works almost as good as it does in Windows. There was some minor graininess that I couldn't get rid of it by changing any video setting. Game locked up on me while in the innkeeper menu.

Occasional missing textures and crashing without Proton-GE

Gamescope "should" prevent the crash of the session when the game freezes. Theoretically.

Cursor problems with alt+tab/Gnome overview/Plasma overview. The best option is to switch to another desktop.
Changing the graphics settings had minimal impact.
The game freezes and the session crashes. Various variations from Gnome/Plasma + Xorg/Wayland did not solve the problem.
Input lag was present in some locations. There was no stuttering in the Gnome session. However, after I started using gamescope, I had no crashes, but the fps became even lower.

gamemoderun %command%
Performance varies between as expected, to significantly degraded. A good run has ~45-50FPS (pretty stable) in Vernworth, a bad run drops to 25 FPS in areas. No in-game graphical settings have an impact on this, it seems to be determined by something outside Proton and stays the same until closing and restarting the game where it has a chance for a good run again.
If there was a way to have consistently "good" runs it would be great. I tried a number of environmental variables, DEs, even launching in Gamescope into its own VT with no appreciable impact. There seems to be some interaction with the overall system that it/Proton isn't able to compensate for and only sometimes do things align for the game to run as expected.

The performance is basically identical to Windows. Great game, just needs some optimising from Capcom.
The game would crash randomly if I used an external soundcard. Switching to the internal fixed all my problems. Also, make sure your audio profile is "Analog Stereo Output", as I experienced crackling when it was set to "Analog Stereo Duplex".

WINEDLLOVERRIDES="dinput8.dll=n,b" LD_PRELOAD=/usr/lib/libgamemode.so gamemoderun mangohud vk_amdvlk %command%
In towns the FPS drops heavily. The only way to make it playable (60+ fps) is to enable FSR Balanced mode.
I tried a lot of ways to get the game running stable on Mesa drivers, with no success.
The game othewise works great, mods included.

Runs better than Windows
For me personally I havent run into any issues as of yet. Have close to 6 hours of play ever since switching to Fedora 41, if anything pops up I will change these notes

Graphic Glitches
I installed ProtonGE 9.25 and deactivated DLSS. I also lowered the graphics a tiny bit. After this, the crashes were pretty rare and I could play like 2 hrs without a problem.

I've tried switching between xorg/wayland, gamescope, different launch options
Insane flickering
Can't change settings, the game flickers and does not allow to change any settings in the menu, also clicking on settings button provokes audio glithed clicking sound.
The game was fine when I've played it like 6 months ago, but now it is a unplayable total mess. Gamescope removes flickering partially, but settings menu is still unreachable.

VKD3D_CONFIG=disable_uav_compression %COMMAND%
Does not start in fullscreen but will change to full after startup logos.
Performance drops in the towns or anywhere with lots of npc's.
With launch options crashing becomes less frequent.
Currently using proton experimental bleeding edge. Launch options seem to help vram spiking and crashing.

launches in not full fullscreen, then turns into full when it gets into the main menu
sometimes reading the controller inputs just stops and switching to a different tab/workspace and then switching back to the game fixes it
stuttering when uncapped. rock solid when locked to 60 fps
crashes whole system/hyprland session sometimes, not sure about the frequency yet

game launches in almost full window on Hyprland and then goes into full window after initial RE Engine and other logos play out

Game was running fine (120 ultra with fsr quality onh 1080p) except the full on system crashes every few minutes.

Using ProtonGE fixed it.

It is playable. Does not perform well, crashes frequently, but playable. Given my specs are below minimum im surprised it works at all.

Deleted nvngx_dlss.dll and sl.dlss_g.dll to stop stretching textures, seems to work? Also unequipping any capes seemed to help, as those cause a lot of texture stretching.
Game has a tendency to fill VRAM very fast, resulting in crashing on Wayland. Happens hourly, although lately it seems to have gotten better with my launch options.

30 FPS isn't great, but it is absolutely playable and enjoyable (though I haven't had the fortune of playing games at 60+ FPS all my life)
Many artifacts (missing and/or stretched textures) unless FPS is limited to 30
must limit FPS to 30
Frequent app halts unless limited to 30 FPS

It's great, but some graphical settings are greyed out and stuck, eg DLSS on auto and can't change to whatever AMD made.

In order to play it on Bazzite without any problem or crash... follow my tips below
-Download the latest version of AMDVLK(https://github.com/GPUOpen-Drivers/AMDVLK), it can be ***.deb or ***.rpm...
-Then just extract it into a folder that you have right to write and read, you're gonna need the amd_icd64.json and amdvlk64.so files.
-Indicate the path of the amd_icd64.json file in steam option with the command 'VK_ICD_FILENAMES=/etc/vulkan/icd.d/amd_icd64.json %command%'
-Finaly...edit the amd_icd64.json file, replace the values of the 2 places with 'library path' , set the path you put the 'amdvlk64.so' file.

MESA RADV crashes, AMDVLK does not.
If you want to play this without crashing on Linux, use AMDVLK. You can install AMDVLK on top of RADV, and set RADV back to the system default afterward, then launch the game with the attached command. That will load the game using AMDVLK and the crashes are 100% gone. Have tested over ~100 hours of playing. No other "fixes" work to stop menu and random crashing.

MANGOHUD=1 %command%
It started in windows-mode but I was able to change that in the options to borderless-fullscreen with no troubles. DLSS is active and the overall settings are high. After creating the shaders, which took some minutes, I could enjoy the game without issues.

Starts out of the box, can't play for extended duration.
After about 1h of gameplay.
Game works out of the box without issues. Very first session ran for 8h with no problem. Next day after 1h game crashed and forced me into my login screen, continued this behaviour ever since.

Frequently crashes the display manager, graphic resets each time launching the game
Some times it works, some times it does not. Some times the game plays fine, but quitting the game, or launching the options crashes it for no reason.

Minor issue - Starts windowed but then automatically changes to fullscreen on the title screen (Same on Windows)
Significant drops in FPS when in City which is an inherent problem to the game and not proton related.
Possibly not proton related, frequent crashes when loading from save file which sometimes crashes the display manager. Seems to have been significantly reduced since last updates.
The most annoying was a permanent drastic drop in framerate that happens randomly when enterring a menu resulting in sub 20 FPS to single digits making it unplayable until a game restart. This happened frequently making it close to unplayable.
THE FIX: As noted the most annoying bug was a drastic drop in framerate when enterring a menu which made the game close to unplayable. Testing with numerous proton and GE versions made no difference. When tested on a Win10 PC with the latest AMD drivers this issue was non existent which seemed to indicate something may have been remedied on a driver update. I then tried HWE , HWE edge kernel and Obaif PPA drivers on Ubuntu 24.04 (Kernel 6.8) which made no difference. Finally, I ugraded to Ubuntu 24.10 with kernel 6.11 and this issue has now dissappeared. Dragon's Dogma 2 is now running "perfectly"...well probably the same as Windows which "good enough".

VKD3D_DISABLE_EXTENSIONS=VK_NV_low_latency2 PROTON_HIDE_NVIDIA_GPU=1 %command%
Some story cutscenes run at half speed while the audio plays at full speed when playing higher than 1080p
If you have an NVidia GPU and experience freezes, try PROTON_HIDE_NVIDIA_GPU=1 and if you have graphical issues, disable DLSS in the settings

Unplayable on most proton versions, crashing after intros. "Works" on 8.0-5 but it's glitching like crazy.
Many glitches and artifacting after few minutes of gameplay
Disclaimer: DON'T change proton versions too often in one day. You will get locked from playing the game for 24 hours by Denuvo...

Slowdown during initial load predicted menu crash issues for that play session; unavoidable except with relaunching, which would have required the menu, or killing the process, which would be marginally better than crashing all of KDE, but menu opens when you lose focus on the application.
Only happens once in a while, and autosaves are pretty frequent. Noticed no fans in my computer are spinning up, so it may be attempting to use a device that doesn't exist to render menus? A guess.
Got a travel together quest from a main quest NPC, wanted to go very far. I escorted her through a nightmare ruin and nearly 2 hours of gameplay, she fell in a lake with no outside interference at the finish line and the quest failed. Love this game.

Ocassional freezes when opening menus.
The game is very playable, but sometimes it freezes after you open some menu. You can recover from this if you have a "show desktop" keyboard combination and then close the game and restart Steam. You can prevent some freezes if you close all other apps. Also i have noticed that the game runs smoothly if you use the variable framerate.

VKD3D_DISABLE_EXTENSIONS=VK_NV_low_latency2 WINEDLLOVERRIDES="version,dxgi=n,b" gamemoderun %command% --dlss-nvapi=mock
DLSS causes models or textures to cover the whole screen.
Looks worse than Dragon's Dogma 1 on minimal settings and still runs like dogshit.
Maximum 1h playing and then it crashes.
Always starts windowed. Resolution setting was wonky in the beginning. Highlighted UI options would sometimes not be in the position they should be in.
I'm sad.

CachyOS, Arch btw, worked with simple launch options and there own version of proton. Works like a dream with most games. No need to keep swapping proton versions with every game. Very close to the dream of, "it just works".

Outside of occasional hard crashes, gameplay is smooth and has no noticable visual or performance issues.
Moderate chance (~20%) of crashing my PC when opening the pause menu during gameplay.

With DLSS activated, the game will show stretched textures after about 10mins of playtime. Without DLSS the game runs really well.

You can activate Raytracing with:

Proton 9 variants all seem to open it and crash when you go beyond the main manu, 8.05 runs but has major artifacting/loading issues.
missing legs etc stretched in odd angles, sometimes blocking view entirely
Game locked up after about 10 minutes, when running toward the rock that falls in the intro
game starts in small window but if you change the resolution and set windowed fullscreen it will correct it, it always launches the small window and then jumps to a full window after loading once youve set a higher resolution

Trying different Proton versions
Frequent graphical issues, such as arms being missing, stretched textures covering the screen, etc.
Game would not start when set to borderless fullscreen on second boot
Trying different Proton versions causes game activations, which Denuvo anti-cheat locks you out of playing the game for 24 hours. Unacceptable.

gamemoderun VKD3D_DISABLE_EXTENSIONS=VK_NV_low_latency2 %command%
some times the textures stretch it happens after playing for 30 minutes or so
when i first started the game i got an error staying "!status && vkLatencySleepNV" to fix this add VKD3D_DISABLE_EXTENSIONS=VK_NV_low_latency2 to your launch options
leme know if you find a way to fix the bug, cause i love this game

Game starts in a window with 1280x720, but I could change in Game Options to 1920x1080 Full-screen.
Sometimes the frame rate go down to 35-40fps, but it's not often.
I also played with Ubuntu 24.04, but got a few unexpected crashes in the first few hours. I don't know why that happened. With Fedora, the game runs stable for several hours.

gamemoderun %command%
X11
Playing in wayland causes crashes and instability. Also problems with stuttering. Swtich to X11
Steam native and not steam-runtime
For me, this game crashes 100% of the time before getting to the main menu when running steam-runtime in X11 or wayland. If I use the native Arch steam package, it works flawlessly. If you are running Arch or an Arch-based distro try running steam and not steam runtime.
