Series X, native Mouse and Keyboard some sort of jittery/stuttering

Some games on the Xbox One or Series X|S do support keyboard and mouse. So if you use a keyboard and mouse just by plugging them into the usb ports on the Xbox console, then no it is not a bannable offense. It can be though if you use an unofficial adapter to play on games that do not support keyboard and mouse.

I dunno I didn't write that post I may have accidental clicked on AI generation by accident

BUT keyboard and mouse isn't .possible on cloud either install it on yoir pc.or run it natively installed on console

Cloud games are still series x version not pc

Xbox allows keyboard and mouse, but it's the developer that builds it into their game. You can change pointer speed in settings, Devices & Connections, Mouse.

I get that but I mean natively, the Series X absolutely has mouse acceleration built in as I have used PCs in the past. In Warzone for example, if you reduce acceleration to 0, it still remains. Messed around with Pointer Speed but that does not affect acceleration.

If the game had native keyboard and mouse support you may be able to use your PCs keyboard and mouse. You can use the keyboard for the actual xbox homescreen though.

Would rather all games support keyboard and mouse natively.
