[2020] Riot's Anti-Cheat software Vanguard is causing frame drops in all my games, including Valorant making them unplayable with the software installed.

Hi! Sorry to hear this, can you submit a support ticket so we can get more information?

Vanguard has always been running while the game has been closed but we thought it would be better to give you a tray icon so you can see that it's running and exit it/uninstall if you like.

Vanguard has a component that runs from system startup to ensure that when the game (and the rest of the anti-cheat) starts the system is in a known protected state. This makes it harder for cheats to be loaded into the system in a way that we couldn't detect.
