absolutely forgot.
Firmware attestation has collapsed millions of players out of call of duty due to the players motherbaords and uefi/bios has fallen by the way side and are no longer being kept up to date.
therefore call of duty has marked the firmware with the attestation, essentially rubbishing millions and millions of PCs unable to play call of duty properly.
Unbelievable really as this is incompatable with all of the anti-cheat programs the call of duty franchise is using to keep the game fair. well as fair as can be inspite of the massive differences in hardware capability.
SO yeah much grumbles around this issue as a matter of fact.
