Runs perfectly OOTB.
Game runs with zero issues OOTB.
Just like with the base game, this one works flawlessly.
And, just like with the base game, I would still recommend playing this one with the source port dhewm3.
Works like native version without any problem.
If you want a widescreen resolution, you have to edit DoomConfig.cfg as in Windows version.

Working perfectly out of the box.

played the first few levels, interacted with terminals, fired several weapons, used the cheat console

Game runs fine. Widescreen/High resoultion requires tweaking some files, but this is the same for Windows. Steam Overlay not showing the cursor while plaing this game.

everything works, but if you want a modern resolution, you have to edit steamapps/common/Doom 3/d3xp/DoomConfig.cfg

Edit: steamapps/common/Doom 3/d3xp/DoomConfig.cfg to a set custom resolution.
