Dynamic Priority
Background applications:
Cacheman will dynamically lower the priority of background applications that use a lot of processing power. The application that is active will run faster this way. You can exempt a specific application from this feature by configuring a Sticky Priority.
Fullscreen applications:
Cacheman will change the process priority of applications that run in fullscreen mode (covering the whole monitor area).
High priority will help reduce lag caused by background processes when playing a 3D computer game. Low priority makes sense on a server computer, where background tasks are more important.
Sticky Priority always takes precedence over Dynamic Priority.
