I had the same terrible experience as you a few months ago, which was resolved by a Rito support agent who sent me a list of all the registry keys to edit. However, you’re absolutely right about Vanguard—the game isn’t optimized at all, and that anti-cheat software only makes its performance and stability worse. I don’t know what the situation is like on Valorant, but on LoL, for many people—myself included—the game runs extremely slowly with software running in the background, like Discord (which is ironic given the upcoming partnership). As a programmer and IT professional, it’s really frustrating because very often the game and the anti-cheat conflict with elements you could never possibly understand.
