5 launch options documented for id Tech, and the 29 games in the catalogue built on it.

Documented for id Tech

An engine flag is read by the engine, so it usually carries across the games built on it. Not always: engine versions differ, and a developer can change what their build accepts. Each game's own page lists anything documented for that game specifically.

How to apply a launch option on Steam

  1. Open Steam and go to your Library.
  2. Right-click the game and choose Properties.
  3. On the General tab, find the Launch Options field.
  4. Type or paste the option (e.g. -windowed) into the field. To use several at once, separate them with spaces (e.g. -windowed -novid).
  5. 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.
