Mod note: Some lag induction techniques listed in this doc are no longer allowed. The only bindings allowed are those available in-game. Changing mouse dpi or editing Windows's key delay is outside the scope of the game and therefore, not allowed.

Holding PrintScreen, binding a key to screenshot_normal using the in-game console, and hitting Alt+G are the only allowed methods of lag.
