Numerous Valorant players were reporting that their mouse and keyboard stopped working and that they weren't able to fix the problem even after resetting the system. Others were reporting that some other programs and features were disabled, like fan control, system monitors, and even some BIOS settings, etc. The worst part is that this was all done silently, without notifying players.


Riot’s anti-cheat is causing more and more concern. The company developed their own state of the art program to fight hackers but it’s currently giving everyone a harder time and not just cheaters. Some users were initially shocked to find out that the program has the highest level of access in their system. Riot were quick to assure players that it’s absolutely safe claiming the only purpose of Vanguard was to prevent hackers. In the meantime, others reported lowered frames per second while the anti-cheat is active. The lower frame rates were affecting games and applications different than Valorant. As a result, Riot introduced an update to Vanguard, which allowed players to stop it or uninstall it much easier. If you’ve uninstalled Vanguard the only way to play the upcoming shooter was to install it all over again and give your PC another restart.The overwhelmingly negative reaction prompted a quick response from developers in Riot, and they quickly rolled out a hotfix which should fix the problem, and allow previously blocked drivers to work. Good news is that they are planning non-blocking solutions for security issues in the future, which should minimize the potential for the unpleasant surprises like this one. The latest hotfix should be available when you start Valorant next time, but you would need to reboot the system after that.

We're working on ways to make the experience better. Our current notification pop-ups aren't as good as they could be and we're looking for ways to give you more control over how Vanguard works. We're happy to do anything we can to make this smoother for everyone as long as it doesn't give an opening for cheaters.

In an hour we're shipping a hotfix for Vanguard to +up its compatibility with cheat-vulnerable drivers. Most of the previously blocked drivers should now work. Some egregious ones will cause the game not to start but now very few will be blocked outright. Thanks for the feedback. — VALORANT (@PlayVALORANT) May 7, 2020

There an exception for "Interception" mouse/keyboard driver, which is still not supported, but now instead of Vanguard blocking it, you will not be able to launch the game. One thing to note is that the "Interception" mouse/keyboard driver is still not supported but instead of blocking it we will not let the game launch if it is loaded. Sorry to the people out there who found themselves mouseless for a moment there!
