    • Accelerator: AlienAdrenaline’s Accelerator is an instant performance booster. It ends process trees for Windows-based applications and services that are unnecessary, giving your system a boost in speed. It won’t permanently alter your system’s configuration, or uninstall any software or programs. It merely sheds some weight temporarily and then returns to its original state once you’re done gaming.
    • Performance Monitoring: AlienAdrenaline’s Performance Monitoring tool provides a graphical representation of hard drive, system memory, network, processor and graphics card usage, so you can track system performance and identify problems while playing a game or running resource-intensive applications. Monitor your performance in real-time or record and review them later.

    Access your system’s power-management controls so you can decide when you need maximum performance or when to scale back for more everyday programs.

    • Quick settings: Get easy access to preset power options like high performance, balanced or power saving modes. Quick settings is an easy interface to fine-tune those settings.
    • Advanced settings: AlienFusion’s advanced settings mode gives you control over how you want individual components in your system to behave while running on specific power modes — like adjusting the behavior of your wireless adapter or graphics processor.
