Glossary:Mouse locking

From PCGamingWiki, the wiki about fixing PC games
Certain games do not lock the mouse inside the actual window, this can result in some rather annoying behaviour on multiple screens or while playing in windowed mode.

Mouse locking refers to constraining the mouse cursor within the window of a game. This is to prevent accidental clicks while the cursor is outside of the game window, causing it to lose focus or possibly even worse. Most games automatically lock the cursor, but for some titles this must be forced through a third-party alternative.


Special K[edit]

Easy to configure in-game GUI. Allows for restricting the mouse cursor in both exclusive fullscreen as well as windowed modes.
Requires games to use an API Special K supports, making it incompatible with some games.
See Special K > Mouse locking for instructions.
