If you have problems with game crashes (especially FF X-2), then just use GE-Proton9-25 to launch. Passed FF X-2 from the beginning to 100% on this version of Proton without a single bug or crash. On the usual Proton 9.04 FF X-2 often crashes. Just use GE-Proton9-25 and everything will work perfectly

Aside from the awful launcher, the game runs nicely. The performance is very nice and the battery lasts 6+ hours.
TDP at 10W
Launcher only works with touch screen, an hassle if you have the Steam Deck on the dock
When waking up from the sleep, the in-game controls would ocasionally not work. Steam deck responded fine but the character did not move.
Toggled the "Disable Frame Limit" to fix a major slowdown in the X-2 experience screen
"Disable frame limit" for X-2 and you'll have a great time. Save before putting the console to sleep, just in case.
Everything works out of the box. Tested everything in the launcher

Using the left control stick freezes the game at times. Hard crash, had to force quit.
This game is a buggy mess. I only made changes to the layout to add F keys to the back buttons of my deck.
That said, continual freezing...the game even autosaved a frozen crash state. Using the left control stick to move caused a hard lock frozen game several times. My recommendation is to disable it, and use the D pad for movement.
The game does work well at times. I made it through Kilika Temple...only to freeze up when the game tried autosaving during the scene change. But the game is not at all stable, and it's a toss up as to whether it will continue or hard crash.
This game as of the latest update from Steam is not what I would call playable. Very hit or miss.
Froze on save screen at save point near dark knight dressphere.

Launcher opens successfuly, Game itself fails to load.

Tried multiple options mentioned on ProtonDb, with/without proton tricks, with and without the launch options mentioned. also tried multiple versions of Proton, (Experimental, 8.0-5 and 6.3-8)
I can reliably make it into the launcher, however the game simply refuses to launch past that.
I tried the suggestion to try and run the game directly from the .exe using Wine Terminal, and I get the following error:
glx: failed to create dri3 screen failed to load driver: nouveau glx: failed to create dri3 screen failed to load driver: nouveau 0024:err:d3d:wined3d_caps_gl_ctx_create Failed to find a suitable pixel format. 0024:err:d3d:wined3d_adapter_gl_init Failed to get a GL context for adapter 03F3D4B8. 0024:fixme:file:errno_to_status Converting errno 12 to STATUS_UNSUCCESSFUL 0024:fixme:file:errno_to_status Converting errno 12 to STATUS_UNSUCCESSFUL
As it stands doesnt look like this is playable at the moment, might have to spin up a Windows 10 VM as a backup.

It works out of the box on old nvidia drivers with old versions of proton (7 os less). Finished the game (FFX, I did not play FFX2).
Lulu's overdrive doesn't work, can't "rotate" the left stick and the arrow keys don't do anything to fill the bar either. Other than that every control works as expected on both inputs.
Play it, awesome story, among the top 5 games in the series for sure.

TDP Limit:10, GPU Clock: 1200
Disabling frame limit, lowering TDP, and GPU fixed the EXP screen slowdown and delay for me in FFX.

Alterar o Framerate no menu causa crashes constante. deixei tudo no max garante estabilidade.

Can't launch through steam. Can launch the EXE directly with system's wine in terminal.

As the title shows. I can open the game exe (FFX.exe) but can't launch FFX&X2Launcher.exe or use the launch button in steam. When launching through I get a font error (System.ArgumentException: The requested FontFamily could not be found [GDI+ status: FontFamilyNotFound]) I am assuming this is the same error steam is giving but I can't see it to make sure.

UnX 0.9.1.9 + Reshade 6.2.0
TDP 10
Game occasionally crashed on launch due to UnX/Reshade not responding.
UnX can be unstable on Steam Deck and older versions have been recommended. Copying the latest Reshade (as d3d11.dll) and the latest UnX to the game folder, then editing dxgi.ini to point to d3d11.dll for Reshade and adding the launch option worked better for me, though.
Forced proton experimental, launch menu is touch based only. Graphics set to high and no crashes. No slowdown at exp screen either.

If you want to play with controller only the default launch window has no controller support but you can use a controller steam config to get around this

I'm playing the X-2 (X HD I played it on my desktop) After finishing a battle you get an experience screen and sometimes takes 10-15 seconds to being able to advance. Game slows down a lot.
Not much to report, I'm playing the X-2 version on the SD and runs pretty much flawlessly out of the box with the exception of the experience screen that loads back into the game very slowly.

Proton Experimental seems to solve common user issues with instability. Haven't had a single crash or problem with gameplay and cutscenes throughout playing on the Deck. I just use the touchscreen for the game launcher. You will have to change the resolution here as it's set to the smallest by default and will crash. I can't attest to X-2's experience as I haven't played it yet. One small issue is that you can't access the in-game system menu with the bonus features using a controller (Need the Esc key.) This is also a problem playing on PC anyhow. You can probably fix this by remapping buttons but I didn't find it was something I needed while playing. Overall a good experience I'd say.

The save and extra menu were white, but it didn't impact anything else.
Only played X so far, but not X-2. I doubt, that there would be any problems though.
Game runs great, no issues

Looks like problems with FF-X2 crashes has fixed. See https://github.com/doitsujin/dxvk/issues/2012 and https://github.com/ValveSoftware/Proton/issues/555 topics for details. There is hack added to wine now https://github.com/ValveSoftware/wine/commit/26425af97506e119f76d636ecc95d647e91afa83 My recommendations: use Proton Experimental or wait while version 8.0-5 will be released. I have not tested FF-X yet, but for FF-X2 no more crashes when battle starts or even in dialogs or changing areas. Played more than 6 hours now without single crash. Since I'm palying on weak laptop video settings is minimal 1280x720 resolution, full screen on, textures high, shadows low, ati-aliasisg (post filter) SMAA low, color correction on, the rest settings set to off or x1.
First startup with settings set to high on default proton game crashed at intro. Switching to Proton GE 8.25 fixed this.

Crashy game and it starts in Japanese. Set Proton to 7.0.6 and change language in the initial launcher in the settings, first window.
Intro crashed with high settings. Start with low and then pass to high
10 W TDP
Game started in Japanese. You need to set it to the language you want into the main menu.
Crashes on intro with high settings (this with dafault proton maybe 7.0.6 fixes this). With UnX mod (compatibility version) it crashes quite much. It's normal for the first few boots to crash but after it should stabilize but I couldn't really get past the cutscene when Yuna almost falls the stairs in Besaid Temple. Set Proton on 7.0.6 and you should be good. Also if you use UnX mod use the following launch: WINEDLLOVERRIDES="dinput8=n, b" %command%
Frustrating experience for me but don't give up and try what I wrote here.

The game is too crash-happy. The timing is inconsistent and ranges between 10-60 minute intervals.
Installed UnX and made changes such as game language, game speed, etc.
Changed the back grip buttons to bind a couple of the built-in game boosters to the appropriate Function keys on the keyboard.
TDP limit to 9w and GPU clock locked at 1000.
Had to install the modified and controller friendly Launcher+. This fixed a couple of key issues I had with the default launcher.
The game uses windowed borderless, although this can be changed via UnX, which I did.
Crashes frequently regardless of Proton version.
Default launcher sometimes launches X-2 when I select X, which leads to a white screen followed by crash. It is inconsistent when it happens, somewhat rare even, but requires a full restart of the process to correct.
I am unsure if the issue is UnX or the game itself. However, UnX has some mandatory QoL improvements that make playing the game without it not even worth considering.

Glitches in the save/load screen.
FFX-2: The game crashes randomly. The game autosaves when loading a different field section (edge of map, when the fade out / fade in occurs), so this is primarily a problem in large contiguous dungeons that have no savepoints and no such border that could be abused for autosaving. Haven't yet found a Proton version that would keep the game stable.
Have not tried FFX yet.

X-2 specifically would previously would crash ridiculously often on any Proton version. Proton Experimental updated on Nov. 8th to fix this issue, no longer needs any special adjustment to run as long as Experimental is forced.

Lulus Overdrive does not work
Had to manually move saves into folder
Had to add the launcher itself as a game, and launch through that.

Untitled" Project X
Wayland causes massive stuttering. X11 works fine though.
Wayland stutters uncontrollably so use x11. I haven't had any issues in X as for X-2 I haven't had any crashes but I'm not to far into the game so take that with a grain of salt. Unless you use a PS controller I don't feel project x is all that needed.

Only one crash after switching to older Proton
On default version of Proton suggested the game crashes as soon as you finish the intro fight or the fight just afterwards.
Switching to older Proton version made the game way more stable, but did crash every so often (after more than an hr of play).
Only tested X-2 on Steam Deck

Only worked after downgrading proton to an older version, been stable after playing for an hour or so, if not it crashes at the starting fight or just after.
Only tested on X-2.

FFX runs perfectly on steam deck with default settings. FFX-2 can't get through first mission. Crashes when battles start.
FFX X-2 only
I put in over 100 hours on FFX using all default settings without any stability issues. Only issue was Lulu's overdrive which was a minor inconvience at most. FFX-2 on the other hand was completely unplayable. Changing proton versions helped a bit but not enouph to make it playable.
Initial launch was in Japanese and I had to experiment in the launch window to set it to English

Lulu's overdrive on keyboard does not work at all. (worked fine on Windows) At some point it became unable to startup, but it was fine after restarting the pc somehow. Does not survive the pc going in sleep mode.

I see about a drop of about 3~5 frames over windows native
FFX-2 is unstable. Cant get past the intro Both FFX&FFX2 crash on launch while docked

FFX-2 needs finagling to get to start. If you manage it, it will crash often (as it does via proton on computer).
FFX-2 crashes often, if you can get it to start at all.

For Playstation button prompts: https://github.com/Kaldaien/UnX/releases/tag/unx_010
Had a user on GE's discord help me figure this out. In order to get Playstation button prompts you will need to use an old version of SpecialK here: https://github.com/Kaldaien/UnX/releases/tag/unx_010 Extract all contents (4 files and 1 folder) into the main install directory with the FFX.exe and FFX-2.exe. Open the UnX.ini and change: Inject=true Also you can change the desired button prompts. For instance, I am using: GamepadIcons=PlayStation-Glossy.dds. Also if english is desired change: Voice=en SoundEffects=en Video=en Lastly open dxgi.ini and change: [NVIDIA.API] Disable=true
03rd May 2023. Game was able to install, launch and start with no issue. Not much tinkering done, all as default! Except FPS at 30, the game is locked at 30 anyways. FMVs plays fine, audio is all good! Launch window you will need to use the touch screen to navigate, these are the changes I made under Settings: Resolution: 1280 x 800, Screen Mode: Full Screen Mode, Video Quality Setting: High. Buttons also reflect as per Steam Deck which is nice especially when doing Auron's Overdrive, etc.
Contrary to all the positive reviews here,not even ffx was running. The initial menu was loading fine, but crashed afterwards
Tried installing MVC2015
Not sure, what changed - but for me absolutely unplayable. Pitty as it seemed to be doing well before.
Always had to alt+tab twice in order switch out of the game
Had one or two freezes on screen transitions but they appear to be flukes
I had a consistent freeze when the game should show one of the last cutscenes in the game and I had to boot into Windows to progress past that point
