I’d be somewhat ok with Kernel anticheat if they would work, but the simple truth is that they do nothing of value. COD has Kernel anticheat with Riccochet and is flooded with cheaters. Valorant has only slightly less cause riot updates Vanguard more often.
But guess what, it usually takes 1-2 days for new cheats to reach the relevant forums, maybe a few days more until they are more widely aviable. At most cheaters have to spend another 5€ every 6 months, but that’s it. They don’t care, the amount of money spent on accounts every other month is already way higher.
The only two things anticheat like vanguard protects you from is script kiddies that google “valorant cheat .exe” and Linux only players. And the former could just as well be filtered out without Kernel level.
