Lag spikes on series x

Funny how I haven't had this issue on my xbox one x ever but when I go on my xbox series S then it just starts having the lag spike issues with my captures.

I get this across any multiplayer game i play, fifa, Warzone and cold war My internet is fine 221mbps download 20 upload 29 latency no packet loss... doesnt make sense

The issues are with the game its self. I’ve also experienced this on Cold War, but it’s nothing to do with Xbox. The game isn’t fully optimized hence the lag spikes and bullets not registering. Happens to me too. It could also be your internet. if your internet isn’t the best you could also lag due to bad internet connection. Try other PvP games like MW and see if you get these issues in there. If you don’t then it’s a optimisation with CW.

Only solution is to use Ethernet with WiFi totally disconnected for no lag it seems

Hello NickD54, I hope everything is going well!

Thank you for reaching Microsoft Xbox Forum support.

I believe your console might need either a network reset or just a system refresh. I would like you to go through the following steps to clear the Mac address and then perform a quick power cycle on your console:

Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear it and the console should restart. It would definitely help if you could restart the internet router while the console is restarting.

After going through the troubleshooting steps mentioned, I invite you to perform a quick power cycle by turning off the console and then unplugging all the cables. After 2 to 3 minutes, re-plug them back again, then restart your console.

Another thing you should check is your NAT type. I would like you to check your NAT type if open because that could sometimes interfere. to check for the NAT type you can follow the steps below:

Settings > Network Settings > NAT type => It should be open.

If the NAT type is not open, you will need to open some ports with your internet provider. These ports must be open for Xbox Live to work: Port 88 (UDP) Port 3074 (UDP and TCP) Port 53 (UDP and TCP) Port 80 (TCP) Port 500 (UDP) Port 3544 (UDP) Port 4500 (UDP).

In case the issue still persists after the previous steps have been performed here is the official link to all the network troubleshooting steps that can help sort this out for you.

In case the issue still persists, the next step would be to perform a reset on the console. To do so you will need to follow the steps below to perform a reset on the Xbox :

Settings > System > Console Info > Reset This Xbox > Reset and Keep my Games and Apps.

Note =>The "Reset and Keep my Games and Apps" option will not cause losing your games, but please be aware that you need to be completely aware of the email address as well as the password of your account before going for it because it will require you to sign in to the account.

I wish you a lovely day, and I hope this helps you out! All the best!

Kind Regards

Stay safe, and happy gaming!
