Riot says Vanguard is not bricking Valorant PCs after anti cheat post causes confusion

Riot Games has clarified that Vanguard is not bricking players’ PCs after a post about Valorant’s anti cheat update caused a major backlash in the community. The confusion started after Riot said “Congrats to the owners of a brand new $6k paperweight” while showing DMA firmware cards, which many players understood as a claim that Vanguard could make whole PCs unusable.

The real situation is more specific. Riot says Vanguard can now stop DMA cheat devices from working when IOMMU protections are enabled. These DMA devices are pieces of hardware used by some cheaters to bypass kernel level anti cheat systems. According to Riot, Vanguard does not damage hardware, disable normal devices, or break a player’s PC. It only blocks the cheating hardware from working with Riot games under those security conditions.

Riot’s anti cheat update targets DMA cheating hardware, not normal gaming PCs

DMA cheat devices are a serious problem for competitive shooters because they can read or manipulate system memory in ways that are harder for normal anti cheat tools to catch. Valorant is built around strict competitive integrity, so Riot has always taken a more aggressive approach with Vanguard than many other PC games.

The latest update hooks into the PC’s Input Output Memory Management Unit, or IOMMU. This security feature helps control how connected devices access system memory. With Vanguard’s new protection, DMA firmware cards used for cheating cannot function while IOMMU protections are active. If someone disables those protections, the device may work again, but Valorant and other Riot games require the protections to stay enabled.

The misunderstanding grew because Riot’s original post sounded broader than it was. The phrase about a “$6k paperweight” led some people to think entire gaming PCs were being destroyed or permanently disabled. Riot later explained that the photo showed cheat hardware devices sold specifically for DMA based cheating, not ordinary PC parts.

The debate has not fully ended. Some players believe Riot’s approach is justified because the hardware is being used to break Valorant’s rules and damage fair play. Others argue that anti cheat software should not affect the usability of hardware outside a running game, even if that hardware is suspicious or commonly used for cheating.

There are also concerns about false positives, which matter in any anti cheat system. Riot says the feature applies to systems attempting to use DMA cheat devices and that normal players are not affected. Still, Vanguard has always been a sensitive topic because it runs at a deep system level, and any new protection will naturally raise questions about privacy, control, and hardware access.

The main takeaway is that Vanguard is not making regular PCs unusable. Riot’s new protection is aimed at DMA based cheat hardware and depends on IOMMU security. The original post created unnecessary confusion, but Riot’s follow up makes clear that normal Valorant players should not see their hardware damaged or disabled by the update.
