Is Vanguard Destroying PCs?

Riot Games' anti-cheat system Vanguard sparked controversy after a post appeared to suggest it was destroying PCs. In reality, Riot forced players to enable IOMMU (MMU), a CPU feature that restricts PCIe device memory access, effectively rendering $6,000 DMA cheat hardware useless without physically damaging anything. The post also covers the broader debate around kernel-level anti-cheat: while invasive, kernel-mode anti-cheat is necessary because user-mode solutions can be bypassed by malicious kernel drivers acting as rootkits. The key takeaway is that any software run with admin privileges poses similar risks to kernel-level anti-cheat, and trust in the publisher is the real deciding factor.
