Riot Games has stepped in to shut down growing rumors that its Vanguard anti-cheat software is permanently disabling players' computers. The developer behind League of Legends and Valorant released a clear statement on Twitter saying it "would not and cannot" brick PCs or otherwise damage hardware. The response comes after a May 19 Vanguard update sparked widespread claims online that the software was rendering systems unusable, especially those using DMA hardware for cheating.
Vanguard is designed as one of the most aggressive anti-cheat systems in the industry. It operates at the kernel level to detect and block increasingly advanced cheats, including hardware-based tools that bypass traditional software protections. On May 19 the update began blocking DMA devices that use SATA or NVMe firmware. Shortly after, players started sharing stories of instability warnings related to IOMMU, a security feature that manages input-output memory access. Humorous memes quickly followed, including images of a supposed "red screen of death" and jokes about expensive paperweights.
Riot itself added fuel to the conversation two days later when it posted a photo of confiscated cheating hardware with the caption "congrats to owners of a brand new $6k paperweight." Many interpreted the post as confirmation that Vanguard was permanently disabling devices. Others reported that even after uninstalling the anti-cheat, their DMA firmware still would not function normally. The situation escalated fast across social media, with some users claiming their entire PCs had been bricked.
In response, Riot posted a direct clarification. "Vanguard does not damage hardware or disable your devices," the studio wrote. The paperweight comment was specifically aimed at cheating hardware that no longer works inside Valorant. The latest update simply enforces standard security protections such as IOMMU on accounts detected using DMA-based cheats. These protections block unauthorized memory access but do not permanently alter or disable any PC components. Riot emphasized that any instability or warnings users see are the expected result of those security features being activated, not deliberate damage from Vanguard.
"We would not, and cannot, impact your PC's functionality in any other fashion," the post continued. Riot added that players can disable IOMMU to restore normal function for DMA devices outside of Riot games. However, IOMMU must remain enabled to launch Valorant. Normal, non-cheating players will never encounter these hardware-related issues because the update only activates on accounts using DMA cheats.
A follow-up FAQ-style post reinforced the message: "no hardware is being damaged and no other functionalities are impacted." The company noted that similar rumors circulated in 2024, when some users also claimed Vanguard updates were causing PCs to fail. At that time Riot stated it could not verify those reports.
The incident has reignited broader conversations about kernel-level anti-cheat systems. DMA hardware has become a serious concern for developers because it allows cheats to read and write directly to system memory, making it extremely difficult for standard anti-cheat tools to detect. Riot maintains that Vanguard remains one of the most effective solutions available, and many players support the company's hardline stance against cheaters. At the same time, critics raise valid questions about privacy, system access, and the potential for unintended consequences when anti-cheat software operates at such a deep level.
Despite the periodic controversy, Valorant continues to thrive. Since its 2020 launch the tactical shooter has maintained strong concurrent player numbers worldwide. It receives regular seasonal updates, new agents, map changes, and ongoing anti-cheat improvements. The game also enjoys a healthy esports scene with major tournaments and dedicated fans.
For most players the latest update will have no noticeable effect. Vanguard's changes are targeted specifically at those using DMA hardware to gain unfair advantages in Valorant. The studio's quick and transparent response appears to have calmed the immediate panic, though the discussion about the balance between effective anti-cheat measures and user trust is likely to continue.
Riot has a history of taking cheating seriously. The company has invested heavily in Vanguard because it believes fair play is essential to the long-term health of its competitive games. While the aggressive nature of kernel-level protection will always draw some criticism, the overwhelming majority of the player base appreciates a cheat-free environment. The latest clarification reinforces that Riot's goal is protection, not punishment of innocent hardware.
As the conversation settles, the focus returns to the games themselves. League of Legends and Valorant remain two of the most played titles in the world, and Vanguard is a key part of keeping those experiences competitive and enjoyable. Players who were concerned about the rumors can rest easier knowing that Riot has drawn a firm line: Vanguard stops cheats, but it does not break PCs. The only people who need to worry, are the cheaters. And we really do not care for them at all. Stay tuned to Gamefragger.com for more video game news, reviews and updates!
