Sometimes the audio will stop playing
Runs perfectly without needing to tweak anything

Works OOTB
Occasional crackling, only seems to happen when certain other applications are streaming audio

Stuttering when playing online
Works great as long as you don't need to play online mulitplayer

error dx11 feature level 10.0 is required to run the engine
The game won't work because there is no directx11, i found out the new protons 9 use directx 12 as default on newers Vulkan, i changed the game to proton 5-13.6 and works normally because the old proton have directx 11 as default. Hope it helps
Works fine out of the box.

I developed a bash script which automates the deployment of Ultrawide fix to combat black bars on the steam deck.
You can find it here.
If you are not familir with Linux there is a step-by-step Steam Guide. Fix requires an older 8.05 proton.
Overall, even without full screen, game is a perfect out of the box experience for SD.
Perfomance is great, game is designed to play with the standart gamepad layout.
Font is on a smaller side, but I personally have not experienced issues reading it.

Very Bad stuttering in multiplayer menu and in game. constient frame time spikes
Seems like every time it uses networking their is a spike in frame times. allways has frame time spikes when you press enter to get into first menu. mutiplayer menu in unseable because of the frame time spikes

Outiside of that 1 bug works great
Sometimes instead of "Press F1 to continue" i get "Press to continue" pressing F1 continues a game

Just don't forget the controller
I played using keyboard, nearly impossible. Everything else was perfect, out of the box.

Multiplayer stutters like crazy. Singleplayer is buttery smooth.
The game works great. At least, singleplayer. Multiplayer was quite a mess for me(extreme lag constantly)

gamemoderun %command%
Multiplayer is so slow and stuttering that is completly unplayable
- Campaign mode - i can play perfectly without any issues.

As long as you don't mind occasional stuttering on multiplayer.
protontricks helps with the stuttering issue but it isn't perfect. But it's much more playable than it is without
Runs out of the box

Can't run with Mangohud 0.7.2. v0.6.5 is ok though.

Played through campaign. Did not try multiplayer.

Superior performance to Windows
Ran perfectly out of the box

Some small text in menus and gameplay but still legible
Ran with CryoUtilities tool active (recommended settings). Defaulted to medium settings in-game, changed AA to FXAA High.
Game sometimes unfocused, during cutscenes or startup stopping cutscene and disabling sound(just click on with mouse to fix)

Mostly Low, slight resolution downscaling, capped refresh to 50Hz.
Menu text can be a little small, if you use resolution scaling some stuff in the HUD can get difficult to see.

Jeu très agréable, aucun bug, aucune lenteur, le jeu tourne en ultras sans problème !
Le multijoueur fonctionne cependant, il possède très peu de joueurs.

Le multijoueur fonctionne cependant, il y a très peu de joueurs, en moyenne un à deux salons sont ouvert maximum !
J'ai joué à ace combat 7 plus de 70h sur Linux, le jeu tourne en ultras depuis le début et je n'ai jamais rencontré aucun souci. Le jeu est super, foncez y jouer !

Runs as it probably would on Windows out of the box.
Minor screen tearing in certain menus and when in Replay mode(upper rectangluar area - probably a special rendering area for the game)

gamemoderun %command%
Some unimportant stuff (preview the plane and some others) in the menu were not bound to any key. (might also be because of my keyboard but I'm not using windows so I can't try)
No issues whatsoever.
How to get it running:
- Install
- Launch
- Profit

Steam says the game is running, but no window appears

I can start the game, the shaders compile, but then nothing happens. I tried using Proton Experimental and Proton GE and neither fixed the issue. Validating the game files, updating my pc, and reinstalling the game did not fix the issue either.
After PC hibernate, wake back up then sound boken like white noise

pequeños lags
Playable on Intel Arc A770
Rare artifacts
Rare slowdowns
Minor artifacts causing slowdowns during the missions but game is playable
Runs fairly well, Just minor bugs for me.
Some slight crackling, I did notice the final cutscene's audio was out of sync.
FPS in menu can drop below where it normally is after playing a mission. Missions after run at the correct FPS.
Runs pretty well, Worked fine with my PS3 DS3 controller.
