Would not go infront of task bar

MANGOHUD_CONFIG=fps_limit=6-,no_display
OotB game flickers and crashes. This suggests a graphics issue. A quick and dirty fix was to use Wintricks on $STEAM_DIR/steamapps/compatdata/32510/pfx to install al dxd11 or dxd9 libraries. I don't know which ones are necessary, maybe you just need any, maybe you need a specific version. Game runs fine after this tinker.
Excuse the launch option typo, it should be 60 no 6-

Terrific game on Steam Deck! Absolutely flawless experience using the GOG Version of the game!
Set TDP Watts to 7
I played Lego Star Wars - The Complete Saga to completion just before I played this, and if that was a 8/10 experience on Steam Deck, then Lego Star Wars III - The Clone Wars is a 10/10.
I own this game on GOG (Good Old Games) and so I installed it via Heroic Launcher in Desktop Mode. As soon as the game installed, I didn't tinker with anything, I simply went back to Gaming mode and launched Lego Star Wars III like I would any other game.
The game booted up immediately and recognized my Steam Deck controller without me having to tinker! (Something I had to do on The Complete Saga) - so straight away, we're off to a good start!
Then the performance was fantastic. Whilst The Complete Saga struggled occasionally with the occasional stutter during the beginning of a cutscene, Lego Star Wars III had none of that!
I had a LOCKED 60fps experience from start to finish. I changed my TDP to 7 watts to help get some more battery life and the fps stayed at a solid 60fps for the entire game.
Happy to say I beat the game on my Steam Deck with zero issues/bugs/crashes. Performance was fantastic at a locked 60fps, the game displayed in native 16:10 which is always nice, and battery life was excellent!
Fantastic game for the Steam Deck!

Black screen or flashing lights in new system
Fedora 40 with nvidia. Used to work on PopOS. Latest Experimental has flashing lights, crashes ofter 5s, and other versions of Proton have a black screen.
I could try using kernel 6.8 as I happen to have it installed in grub2.

Graphics broken on home screen soon after crashs.
Every texture shown is a flashing rainbow of color

Enable Fsync / Esync
Had to install d3d9_41
Just remember to install d3d9_41 or later through winetricks. Otherwise game will not launch and crash.
Had crashes on Windows 10, but on Linux this one just runs perfectly out of the box.

tdp set to 7 watts

install d3dx9_41
Background elements would not load

Generally work. They are sometimes linear artefact like in old tv, but game works pretty good

214510 d3dx9_41
it is necessary to install protontricks and the dll d3dx9_41 is already in it. without installation, the game starts with the keys and crashes. If you install dx3 in the common space, then it must be done once and all the old LEGO games (most likely and not only) will work
Works perfectly fine
Graphics broken on home screen with fastly blinking colors and soon after crashs.
The games graphs breaks on startup with blinking lights and crashes soon after.
It very broken.
It would boot the title screen but wouldn't load any actual levels until I turned off enhanced graphics. There was no problems after that.
GPU 200Mhz, TDP Limit 3W, Refresh Rate 40Hz
Some glitchy artifacting on and around fire effects
Works just like Windows without any modifications needed.
Last time I checked, Windows also has these issues.
Game starts, but i cannot move -no controller support whatsoever. Tried Xbox360, Logitech 310, and Dualshock 4
Enjoyable experience
Platinum. Install and Play.
No Proton command was needed, everything worked perfectly in the first 30 minutes. Xbox 360 Controller working perfectly.
FPS drops during the elevator drives.
I experienced 1 crash during my 15+ hours playthrough

Main menu lags when selecting making navagation almost impossiable
This problem was solved by disabling the steam overlay
Buttery smooth perfection out of the box
Finished the whole thing on 100 % (about 35 hours) without anything I'd consider a major issue. Had it crash for about 9-10 times though.
Some cutscenes would lag heavily and/or mess up completely (e. g. black screen or weird aspect ratio).
Some menus took a few times to recognize button input from my XBox One S gamepad. No impact on actual gameplay.
The game would crash a few times for unknown reasons when I played it for several hours on edge, then ran fine again for a few more hours.
Works like a charm
Worked with my Xbox controller too, just plugged in and it was ready to go!
Ran perfectly out of the box on native 4K @60 FPS; both XBox One S and Nintendo Switch Pro Controller fully supported.
I tried vanilla WINE 5.19 before with the retail version of this game, which always crashed after about 30 secs in-game. The Steam version however works perfectly fine for me with default Proton (3.16 I assume).
It crashed on me 45 minutes into my first game play. I changed Proton to a version 5, and played 4 more levels without issues.
Crash to desktop after 1-2 seconds at the main menu splash screen.
Ran out of the box with Xbox 360 controller support.
The game runs flawlessly
This games is whitelisted for Proton 3.16. In order to use the latest DXVK improvements manually select the most recent Proton version

This game is working perfectly out of the box!

The game works fine on Proton out of the box. I installed manually D9VK and it worked as well without any major issue, only some rendering issues in cut scenes.

Won't start, tweaks have no effect. Using Steam Testing recommended Proton version.

Game crashes to desktop after the two static splash screens, presumably as it tries to play the first video. Haven't had any success in disabling them. Tweaks have no effect.

Runs flawlessly - controller support worked fine for me if it was plugged in when launching the game

Runs perfectly - no issues
