Xbox Series X controller huge input lag (0.5-1.0 SECONDS!)

im not sure if it's an issue with my controller aging or my new Motherboard's Integrated Bluetooth (MSI MPG x570 Gaming Edge Wifi) that has been causing issues with the response with bluetooth. It takes forever for the controller to connect to my PC, but
when it does connect it either works fine for 5 minutes then has extreme input lag, or it cancels the pairing and I have to reconnect, thus looping to the input lag issue.

now the response issue I'm referring to is that the controller has massive lag in responding to my input or missing my input entirely. an example is me playing Battlefield V and my right stick response is either nothing or a delayed response (0.5 - 2 seconds)
then the camera will pan almost 180 degrees. same thing happens to the ABXY buttons, left stick, and triggers.

I need help in figuring out if I need to buy a new controller or if I should ditch the controller completely.

Thanks.

Even i have bluetooth issue with the same Mobo. Signal is veryy weak.

Since you've already gone through the troubleshooting steps and the controller is only 2 days old you have two option. You can either check with the retailer for a possible exchange/refund, or get in touch with the customer support for further assistance. If you happened to purchase the game from the Microsoft store then you will need to get in touch with the online team and they'll take in charge.

If you happened to go with the online team option you can access Contact us | Xbox Support, follow the instructions after clicking on the green button "Contact us" and choose to get help either from an online chat agent or request a callback. Make sure the region on the support website is set to your correct region in order not to find issues with the steps.

On Xbox Series X when some games like Doom Eternal, Crash Bandicoot 4, Psychonauts 2, Tales of Arise and Visage are launched (only Xbox Series X enhanced games and not all of them) any Xbox Series X controller incur in an input issue, with battery and with USB cable without battery: if any key or trigger is pressed rapidly it doesn't work, a sort of input lag. The issue persist in any dashboard menu, then if I turn off and turn on the controller again the problem disappear until I return to the game in background that caused the issue. Any Xbox One X controller works perfectly instead. Both Xbox Series X and Xbox Series X controller are update with the latest update. I noticed that when the issue start the usual buzzing noise of the controller change sound, a lower sound. If I plug any headphone with or without microphone in the Xbox Series X controller the commands are more responsive but the problem remains. I reported more and more times this problem to Microsoft since 3 months but still there isn't an update that resolve this issue with my great disappointment. I think this issue started since about 4 months after a system update, and I think the problem is the same of yours. Can you confirm this?

Not yet, still looking for a solution.

Totally agree with you, I wasn’t expecting this. They fixed the issue a little bit with the last controller firmware update, it improved around a 30-40% in my opinion. For some reason the controller works better with them default profile, I created a controller profile with no vibration ( I thought no vibration would help) but that didn’t helped the cause. Still looking forward for a solution.
