Riot Games introducing Vanguard On-Demand, allowing anti-cheat to run only when League of Legends or VALORANT are active instead of constantly in background

Riot Games has introduced Vanguard On-Demand, allowing League of Legends and VALORANT players to run Vanguard only while playing supported games.

Riot Games has revealed one of the largest updates to its Vanguard anti-cheat system since it launched. Vanguard On-Demand will let players run the anti-cheat service only while League of Legends or VALORANT are in use, removing the requirement for it to be running constantly in the background.

The On-Demand functionality should address one of the largest issues players have had with Vanguard since launch. The kernel-level driver began launching automatically with Windows and sat in the system tray whenever Riot games weren’t being used.

With Vanguard On-Demand, the behavior will change. Instead of always running in the background, the driver will automatically launch when users begin a supported Riot game, and shut down after players exit. For users who don’t want to switch to On-Demand mode, Vanguard will continue to run as normal, as the update is entirely optional.

Not every player will immediately be able to take advantage of Vanguard On-Demand, however. Riot also introduced a new security verification tool called Vanguard Pre-Check that determines if a user’s PC meets certain hardware and OS requirements before they can enable On-Demand mode.

Players will need to be using Windows 11 version 25H2 or later and have UEFI Secure Boot, TPM 2.0, Virtualization-Based Security (VBS), Hypervisor-Protected Code Integrity (HVCI) and IOMMU enabled.

Riot claims that roughly 35 percent of players should meet that criteria out-of-the-box due to modern hardware and Windows’ default settings. Some users may need to manually enable certain features within their motherboard’s BIOS menu.

To make that process easier, Riot is introducing a new version of VGTray, its background utility that sits inside the system tray. If players attempt to enable On

Demand mode without meeting the necessary requirements, VGTray will list what features are missing, provide information on where players can change those settings, and link them to official support documentation.
