Riot's Vanguard is the only one that needs to start with boot, and always run in the background. Others can initialize and close when the game is done, IIRC. Which is why they can work with proton/wine.

Supposedly it falls back to usermode anticheat on linux. That's what I heard but there wasn't a source, so could be BS.

That's where I'm at with the game.

Like yeah it looks fun, I'm not willingly installing malware. Especially after the apex legends debacle.

Thankfully on linux we have tools to heavily limit it's access such as firejail. It doesn't just get unrestricted root access

Their explanation for it makes sense though. They were running into the problem that a player could cheat and progress their games faster, etc. Since HD2 is essentially a MASSIVE, single DnD campaign that every player is a part of, those cheaters would break the campaign progress and ruin it for every single other player.

They also include shortcuts to install and uninstall only the anticheat. So you can remove it immediately once you finish playing.
