Sometimes, the loading screen from initial launch may take a little longer than anticipated. Otherwise, the game works well though.
Use Luxtorpeda so you can launch this game using the native Linux build of the source engine. Requires Source SDK 2013 Singleplayer and Steam Linux Runtime to be installed through steam, though.
Runs just fine on default Proton
In rare cases, fullscreen might revert or not work. If that happens, just switch from window to fullscreen in the game options (or vice versa). Solves the issue.
Tried last 5 Proton versions, could not get it to work
With Proton Experimental and Proton 8/7, it has some sort of VRAM leakage, and fills up 24GB of my GPU VRAM
Played through the whole game with no issues. Once I changed the control layout it played almost exactly like regular Half Life 2
Remapped the controls to match as close to the Half Life 2 control layout as possible.
Limited FPS to 40
Menu text is pretty small and can be hard to read.
Installed and ran perfectly.
Enjoyable little mod. Short but sweet.
Short HL2 mod, runs perfectly out of the box
HL2 Downfall is a short fan-made mod; it runs quite well on Proton
Download and Play
There was no need to make any additional configuration, just downloaded and played!
Use d9vk for better performance.
