# CODM bullet registration drops over time on AMD CPUs (TAC time-drift fix)

While playing CODM through GameLoop / TAC, shots that visibly hit the target stop registering as kills after 10–20 minutes. The bug is intermittent and gets dramatically worse on AMD Ryzen CPUs:


  First few matches: shots register normally.
  After 10–20 minutes of gameplay: 30–60% of shots fail to register damage even at point-blank range.
  The user's ping looks fine; FPS looks fine; the shots simply don't connect.
  Restarting the emulator restores normal registration for another 10–20 minutes, then the cycle repeats.


Root cause confirmed by community: modern AMD CPUs experience clock time-drift when the Windows hypervisor / TAC's internal time reference fall out of sync. CODM's anti-cheat shot validation then rejects shots whose timestamps don't fit the server's expected window.
