Slowdown utility

From Wikipedia, the free encyclopedia

A slowdown utility is software designed to make a faster computer run slower. Typically this is used for running old games. In the 1980s, utilities such as SLOW and SLOWDOWN were used for this purpose. Mo'Slo is a modern slowdown utility that uses command line switches to select a slowdown factor. An example of a (non-free) Windows-based slowdown utility is CPU Killer. Emulation is an alternative to using slowdown utilities; for example, Dosbox can be adjusted to run at various speeds.

[edit] Methodologies

Many slowdown utilities work by eating up CPU cycles. Bremze (Latvian for 'brake') slows down PC performance by controlling the speed of execution of programs.
