Great
no notes. works like it should. no tinkering like its meant to be
Works great out of the box

It had a steady 60fps when first installed but after restarting the system I experienced drops to around 50-55fps

Game freezes when countering a throw
While playing through the tutorial, the game asks you to counter a throw. The moment I counter the throw and get a burst of blue effects, the game freezes. Music continues but the rest of the game is frozen, with a still screen of the moment. This happened no matter what Proton version I tried, and also happened trying all of the launch options people list here.

Apart from the "white fog" bug, this works better than on windows for me
Sometimes a white "fog" covers most of the stage. This happens very infrequently and rebooting the game fixes the problem.
LD_PRELOAD="" gamemoderun %command%
Sometimes some textures got bugged and show as a big and luminous whit stain
gamemoderun LD_PRELOAD="" mangohud %command%
For fixing dropping frames during online play sysctl kernel.split_lock_mitigate=0

Without Proton-GE I got some awful white blotches where particles should've been on stage. Do yourself a favor and use Proton-GE.
Works flawlessly through steam

It works fine with default proton configuration
gamemoderun mangohud %command%
When playing a online match the game fps would drop to 40 when everywhere else it was fine. Had to run sudo sysctl kernel.split_lock_mitigate=0 and it fixed the problem. Doing it the terminal only changes it for that session so you'll have to search up for your specific distro on how to change it permanently. You could also try what I did below.
sudo vim into ~/etc/sysctl.d/50-split-lock.conf
add a line kernal.split_lock_mitigate=0 save and quit
In the terminal use this command sysctl -p ~/etc/sysctl.d/50-split-lock.conf
Reboot
Bazzite makes running this game easy.
Runs perfectly out of the box. As good as Windows on gameplay; No stuttering, input lag or anything.
Nothing works. I tried every Proton version, every command but this game won't start at all.

Textures on certain stages will occasionally fail to load correctly. While you can still play the game in this state, the incorrect textures results in colorful and extremely distracting opaque objects. Forcing the game to pre-compile (called "shader warming" in SF6) textures isn't guaranteed to help.
Occasional texture issues aside, this game generally runs well, even in online modes.
As the other reports have mentioned, you may experience poor performance online if your system has the split_lock_mitigate
setting enabled.
Game mode can automatically toggle the setting when you're playing. Make sure that your user is in the gamemode
group or the performance fixes related to split lock won't be applied.

Logging in the first time for online play is annoying. When the on-screen keyboard pops up, all the input fields are outside the viewable part of scrollable panes.

There's no real touch screen support, it's just a mouse. Touching the screen while in play sometimes switches the game to displaying keyboard controls. Pressing A, B, X or Y reverts it.
World tour fights run at around half the normal speed until activating the option to limit these to 30 fps in the settings.
Runs fine with all graphical settings at max, except the option to limit world tour fights to 30fps needs to be activated for these to run at normal speed.
gamemoderun %command%

Runs the same as windows, no issues locally or playing online.
300+ hours on this title, 1/3 on Linux. No issues

Sometimes particles are blown out bright white making it unplayable
Ignoring the graphical glitch everything works perfectly
Online battle run at half speed, regardless of connection

Texture issues
- Extreme issues where textures break and either permanetly stay like that or rapidly flutter
- Minor issues where textures briefly stretch and snap back
Occurs most often in World Tour mode, which would also cause the game to freeze, and improves once subsurface scattering is disabled and the internal rendering is changed from 5 to 4. Even with these changes the problem still occurs semi-frequently in Fight Hub, and World Tour is effectively unplayable.
Freezes and crashes
Graphical glitches are often accompanied by the game freezing/crashing soon after.
I've been able to play ranked quite happily, and if that's all you care about you can definitely play it, but not being able to play World Tour and get outfits is a bummer.

The game is fully playable with no decernable input lag nor crashes, the only exception being a slowdown issue from having multiple monitors
LD_PRELOAD="" gamemoderun MANGOHUD_CONFIG=gpu_name mangohud %command%
An intermitent and seemingly random "stutter" effect occurs, but it is not related to any hardward slowdown or overload. After attempting many fixes (including reinstalling/downgrading nvidia drivers, installing the flatpak version of steam, changing proton versions, and tweaking nvidia driver settings), it seems to be an issue related to the X11 display server. If you are using multiple monitors with different framerates, this hard to describe framedrop-esque effect occurs. The framerate/responsetime/GPU activity doesn't actually change, but visually, the slowdown occurs. If I unplug all but the main monitor, the issue disappears.

Couldnt get past the versus screen
Tried with different proton versions, always got engine crashes on the versus screen or when loading the multiplayer hub

on higher graphics settings I will often see player models tear in extreme ways, obscuring all other elements on screen
the more content I load the more likely a crash is to occur.
Tinkering has changed nothing in my experience.

sed -i s/"ShaderWarmed=TRUE"/"ShaderWarmed=FALSE"/g /home/$(whoami)/.local/share/Steam/steamapps/common/Street\ Fighter\ 6/config.ini && gamemoderun %command%
Force shaders to be warmed at every startup via launch options sed command.
Without gamemoderun, the framerate may be choppy in battle.
Crossplay does not work. Matchmaking will never pair you with some console player and if you try to play with a friend on console in a custom room, the game will be in slow motion. Tried many Proton versions, many configs, docked with cable internet and wifi. PC vs PC works flawless though.

mangohud gamemoderun %command%
Rarely, there is a shader issue which turns dust and smoke into really colorful clouds. Happens only on some stages, usually goes away quickly.
Very rarely, the game hangs your entire computer. Happens once every 3-4 month, not more often.
You definetely need to make sure that either you or your gamemode disables the split lock mitigation - see other comments or game issue in Proton repository. Otherwise, it's perfectly playable. Mods also work.

the fps drop ploblem
I was able to solve the fps drop problem with the following. Thanks for the info.
sudo sysctl kernel.split_lock_mitigate=0
No problems with World Tour and Fighting Grounds. I haven't tried Battle Hub.

Playing Fighting Ground works fine, but only after tweaks. For me Battle Hub is broken.
After a recent update the game runs at a low fps due to splitlock protection. It can be disabled by running
$ sudo sysctl kernel.split_lock_mitigate=0
(I followed these instructions.)
After which, the performance is good.
Sometimes things like smoke and paint effects don't render correctly
Game seems to always soft lock in Battle Hub, when interacting with just about anything. Not nice since I would like to play sets longer than ranked ones. (I haven't tried the single player mode to see whether it has the same issue.)

× I used the experimental version of proton. The frame rate dropped.
Since updating to version 1.0620.000, the frame rate has consistently dropped to around 15fps, including in the menus. The game is virtually unplayable. I had been able to play for over 500 hours up until the day before the update.

gamemoderun %command%
Normal fights OK. Open world gets slow depending on the part of the map.
In case of reinstall it stops working
Once purchased backup your game and prefix related folders as it stops working if you have to reinstall this game through steam client. It simply crashes on new installation. I looked for a solution with the community without success. I tried to change to GE version of proton and the standard versions offered by steam gui. No progress.
There's a dialog box with a link to a page with the following message: "your game purchase cannot be re-validated successfully, please wait 24 hours and try again."
It does not seem to be so simple as via cli you can see the messages related to part of installation program not being loaded related to contract form.

Screen Flickering on fullscreen

Disregard my previous post. I can't alter or delete it. Setting all graphical settings on the highest options will cause slowdown. These settings work best for me:
- Resolution: 1280x720
Basic Graphical settings:
- Fighting Ground Background Object Density: Crowded
- Internal resolution: 5
- Display mode: Borderless Windowed
- Maximum Frame Rate: 60
- Ambient Occlusion: on
- Screen Space Reflections: off
- Motion Blur: on
- Vsync: on
- NPC's: crowded
- Subsurface scattering: on
- Antialiasing: on
- Depth of Field Effect: on
- Limit World Tour Battles to 30fps: on (mandatory on SD)
Detailed Graphics Settings:
- Lighting Quality: high
- Texture quality: highest
- Mesh Quality: normal
- Shadow Quality: normal
- Shader Quality: high
- Effects Quality: high
- Sampling Quality: standard
- Bloom: off
Now hit the streets!

Works out of the box without tinkering. It defaults in-game on the lowest graphical settings. Simply go the the Settings - Graphics - put everything on High/Highest with resolution on the highest. The game will run fine with these settings and it makes quite a difference. Also, enable the option in the Graphics-menu to lock World Tour at 30 FPS. It's perfectly playable. Haven't testen online battles.
