Come February 19, Epic Games says Fortnite will require additional hardware features to help prevent cheating in tournaments. Two of these you probably already know about, these being Secure Boot and TPM, but the third you might not be so familiar with.
This latter feature is IOMMU, which is part of a motherboard and helps ensure there are no untrusted devices attached to your system. Most modern motherboards have it—Epic says "If your PC is Windows 11-compatible (~95% of Fortnite players on PC), you likely already meet these requirements", including IOMMU—but you might need to enable them in your BIOS.
