the game works flawlessly with the 60 FPS mod albeit with some physics issues, search PC Gaming Wiki for the details.

Game work fine with proton 8.0.4 and cutscenes work fine no bug at all. 30fps every that 2nd world not have bugs used to be report think should he move to playable now not alot of bugs anymore at all.
Yes it work fine every bug on world happens early game does not look it happens anymore and game run good 30fps. Don't go over it.

Able to play through entire game, only occasional crashes, setting up Winetricks was the most difficult part.
Wine-GE-Proton 7.27, Winecfg set Win 7, created 32bit wineprefix
Select controller config window, touchscreen yes to use controller instead of keys
Once during playthrough texture was missing but did not cause crash, texture loaded after reboot.
Occasional crashes, especially when replaying a level multiple times due to character death, crashes on next section load after deck goes into sleep/screen timeout.
Amazon game installed through Heroic. Downloaded missing sounds and patch from GamePressure, Winetricks was the most difficult part to set up, used other reports on here and WineHQ for specific dlls required. Had difficullty with 60fps patch, so I set Heroic and deck to cap FPS at 30. Only really encountered occasional crashes while playing on Sith Master and dying multiple times in the same battle, typically >5 times. Restarting deck would give me some more tries to finish battle and move on.

Worked fine once everything was set up, but setting the game up and figuring out which DLL overrides I needed was a pain in the ass.
Used winetricks to install d3dx9-43.dll, binkw32.dll and DirectX 9 abd set DLL overrides.
I also renamed SWFU.exe to SWFUold.exe and SWFU Launcher.exe to SWFU LauncherOLD.exe, and downloaded a 60fps patch from https://www.gamepressure.com/download.asp?ID=69368 that I put in the game files and named SWFU Launcher.exe, in order to bypass the launcher at startup.
If you don't know about winetrick and DLL overrides (I didn't), learn how to use them. Once I got everything figured out it was pretty straightforward. The hard part was finding out what I needed to do to get the game running.

If you buy from other source lime Amazon, this is the way I was able to make videos work. It also shows the stars in the loading screen.
I had to install Directx 9_43 and maybe bik dll too
On desktop mode, I was not able to make Lutris run my ps4 controller.
No issues in game mode
I got the game from Amazon Prime, I had to use Heroic Launcher to install but videos were blank with audio only. Lutris was the only way I was able to make them work.

Needed sound files from the pc gaming wiki.
5 watts. 500 gpu.
A lake in the junkyard level looks really bad.

This game plays perfectly on Steam Deck right from the start, with default Steam settings (no Proton was selected)
Valve lists this game as unsupported for Steam Deck, but I think the Playable rating would be more accurate.
Once you start up the game, you'll be greeted by a launcher window. The only settings you need to change are the input device (from Keyboard to Xbox 360 controller), and the resolution (from 800x600 to 1280x800, the Deck's native resolution). High Detail can stay enabled.
After that, the game performs flawlessly. The game is programmed run at 30FPS and maintains that frame rate perfectly, and the default controls work without a hitch.
For those that want to, you can go into Steam Input to set the left trackpad to Joystick (not "As Joystick ", just "Joystick "). This way you can control the Force Grip through the left and right trackpads, since the right trackpad already emulates the right joystick by default. I would recommend playing around with the trackpad sensitivity settings to your liking, or I've also submitted a community layout with my personal Steam Deck setup for others to try.

Enabled controller support in the config file not via the launcher.
Videos were playing with a black screen, only sound was playing.
Played the GOG version with 40 FPS patch applied. Video playback wasn't working properly, GE-Proton didn't help. In the end, I deleted the "FMV" folder containing the .bik video files and watched the prerendered cutscenes on Youtube. Btw deleting the videos cut the game's size by ~1/3 and skips the startup sequence. As I already played the game on PS3 back in the day, I knew the story and skipping/watching the videos on Youtube wasn't a big issue for me.
Gameplay worked great without any issues! Played through the main game and the DLCs without any issues related to gameplay. (The DLCs cutscenes are all realtime, so the prerendered cutscene issue didn't apply to the DLC)
In rare cases the game sound randomly stops working. After a game restart the sound is back.
Overall the game is working out of the box (you'll need to select the correct game resolution and the xbox 360 controller the first time on the game launcher).
You need to use a text editor to change a text file and you need to rename two files. If you want 60fps mode you need to download a patch. Instructions below.
Config.xml needs a small text correction
Go to desktop mode, go to https://www.gamepressure.com/download.asp?ID=69368 and download the 60fps exe.
This download is called swtfufpsfix17022015.zip and you only need to extract the .exe file thats inside this zip in the 60fps subfolder.
In steam os desktop mode in Discover app (the blue shopping bag icon), in the search bar beside the home icon on the top left hand side type "text editor" and install a text editor.
Open dolphin (the folder explorer that steam os uses), click the burger style (3 horizontal lines) button on the top right hand side to access dolphin options and make sure Show hidden files is ticked.
Under "Devices" on the left hand side of dolphin file explorer (you may need to scroll down), select home, which will allow you (by clicking the "deck" folder) to navigate to /home/deck/.steam/steam/steamapps/compatdata/32430/pfx/drive_c/users/steamuser/AppData/Local/Aspyr/Star Wars The Force Unleashed and open config.xml with the text editor.
Set video width to 1280 and height to 800 by replacing the numbers listed in the respective tags. Change IsKBAndMouse to FALSE (just delete true and type FALSE). Now close the file and save.
Scroll down to removable devices in Dolphin on the left hand side and choose "primary" then navigate to steamapps, common, star wars the force unleashed. Put the 60fps exe here. There is a file in the folder called SWTFU Launcher.exe. rename it to SWTFU LauncherOLD.exe
Then rename the exe from the 60fps folder as SWTFU Launcher.exe
It should work in desktop mode and also gaming mode now.
If you don't have the 60fps exe download, just rename the file that already exists in the same folder called SWTFU.exe and call it SWTFU Launcher.exe
This will work with controller and will launch properly but it will be in 30fps.
