Packet burst can appear with stutters or rubber-banding, but a network spike and a local frame hitch need different fixes. Test whether the warning follows every match and whether your ping or packet-loss display also changes.
Work through these checks
Check service and scope
Check Activision online services and your platform network status. Try another match and ask whether squadmates see the same issue. If it starts after a service problem, wait for an official update instead of changing router settings.
Stabilize the connection
Pause downloads and streams, then restart your router and system. If possible, test one match on Ethernet rather than Wi-Fi. Compare your in-game ping and packet-loss values before and after; this helps separate connection trouble from a rendering hitch.
Check for PC stutter
On PC, let shaders finish loading, close heavy background apps, and test a lower texture or streaming setting. If the image freezes while ping stays steady, investigate frame-time and storage behavior rather than forwarding ports.
Escalate with evidence
If every match is affected, run the platform’s connection test and note your region, time, connection type, ping, and packet-loss readings for Activision support. Avoid random registry tools or third-party “ping boosters.”
Common questions
Is packet burst always my internet?
No. Similar stutters can come from the client or service; compare ping and frame behavior.
Should I open ports first?
No. Start with service status, a wired test, and your platform’s network diagnostic.
