i highly recomment playing the game Using The Force Engine source port for the best experience
i made the config
simply download The Force Engine, extract the folder contents, move everything to the "DosBox" folder within Dark Forces game files, then rename "dosbox.exe" to something else, and rename the The Force Engine executable (TheForceEngine.exe), to "dosbox.exe"
now when running the game through steam, The Force Engine version will be played instead, the only downside is that cloud saves wont work, and The Force Engine saves are stored within the compatibility files, in a folder named "TheForceEngine" in Documents

Game was stuttering with about 20 FPS.
I followed the guide found below and it is great. I downloaded the windows version and just copied it at the appropriate folder and renamed it. It runs wonderfully.

Other configuration that suited me is disabling the haptics of the left stock and the right trackpad.
Game was running at about 20 FPS prior to installing the force engine.
Runs without any Proton version changes needed. Custom controls are needed if expecting to play it with Controller/Steam Deck Controller - joystick isn't recognized for proper aiming. I recommend using Purple Tentacle's DF layout then customizing further from there as desired.

Created a layout specifically for The Force Engine
I decided to compile TheForceEngine and have Steam run that instead of using DOSBox. In DOSBox, either with Luxtorpeda or with Proton, there are weird framerate issues when shooting enemies. It made the game difficult to play.
Make sure to use Proton 7.0-2, other versions don't seem to load it.
