One of the primary causes of perceived "lag" is the game’s internal framerate limiter, which often conflicts with modern high-refresh-rate monitors.
Prototype 2 was developed during an era when dual-core and quad-core processors were standard. Modern CPUs with 8, 12, or more cores confuse the game's scheduling logic. This confusion results in erratic framerates. Restricting the game to use fewer CPU threads immediately stabilizes performance.
