you can’t install valorant from steam, so valve isn’t involved in tencent’s anti cheat rootkit.

i’d love to know if marvel rivals needs one though, if you have a source

Nope.. maybe. Valve now requires anti cheat to be present on the store page. Highlighted in yellow along with EULAs and 3rd party login.

Apex Legends did not have kernel level anti cheat even though recently they block linux/steamdeck users. Marvel Rivals[1] does not. A store page of game with kernel level anti cheat would be Delta Force[2].

Then again, I'm not sure how true this is since I'm pretty sure its the devs responsibility. GTA5 apparently added anti cheat[3] but their store page didn't indicate any.
