Runs the game with lowest resolution images, lighting is ignored, particle effects are ignored (use this if you are having lag on CHAD, Dr. Fetus, or levels where you die from moving platforms)
Runs the game at the lowest detail, parallax is taken out, particle effects are ignored, animals are missing, set pieces are gone, lighting is ignored, images are lowest possible resolution (made for integrated graphics though not officially supported)
Draws FPS, frame timing and CPU/GPU load over Vulkan and OpenGL games. MangoHud runs the game, so %command% is what it runs.

How to apply a launch option on Steam
Open Steam and go to your Library.
Right-click the game and choose Properties.
On the General tab, find the Launch Options field.
Type or paste the option (e.g. -windowed) into the field. To use several at once, separate them with spaces (e.g. -windowed -novid).
Close Properties. Steam saves automatically, and the option applies next time you launch the game.
To remove one, reopen the same field and delete the text. Options are game-specific; an option that helps one game may do nothing (or misbehave) in another.
Worth knowing: a launch option can break a game's rendering, reset local settings, or trip anti-cheat in multiplayer. Read the description first, add one at a time, and treat anything rated above Safe as a deliberate experiment.
