COD MW4 联机需更新 BIOS

You might need to update your BIOS for COD MW4 online play

Call of Duty: Modern Warfare 4 launches on PC this Friday, and Activision requires TPM 2.0 and Secure Boot for all online modes including multiplayer and DMZ. Intel PTT versions 302.1.2.X or 303.1.2.X and AMD fTPM 3.X.0.X are incompatible and need a BIOS update, which can be checked via tpm.msc. Two PC Gamer colleagues on an Intel Core i5 12400KF and an AMD Ryzen 5 5800X hit the issue because their BIOS versions were years old.
