Stuttering when pressing 3 (gadget one like defibs and others)

Yes, I posted this in another thread.

It's an EA anticheat bug that causes an insane DPC latency spike.

The reason for this is that EA anticheat looks for every button you press. When you press Alt, the anticheat is bypassed, which means every other input goes in one string to the CPU.

EA anticheat somehow doesn't see the Alt key as a threat (maybe because the Alt key is used for Windows shortcuts). It's still not 100%, but it's way better than it was when not using it.
