Topic: Xbox Series X Mouse and Keyboard Latency vs PC (XBOX next console fix?)

Hello,
I'm wondering if anyone has tested the latency difference using keyboard and mouse on XSX or PS5 vs a PC. Playing Warzone with keyboard and mouse feels so much better on my PC with a GTX 1070 than it does on my XSX despite the XSX running at 120hz and the PC around 90.

Is there an inherent reason for this?
Could a software patch fix it on XSX
Would the next Xbox be able to fix this issue?

PC specs are an i5 8400 and GTX 1070 vs my XSX hooked up to a 240hz 4K OLED using peripherals through KVM on the monitor (MSI 321URX).

A couple of years ago I tried Metro Exodus on my Series X with mouse and keyboard but the latency was noticeable and distracting compared to playing it on PC. Tech may have advanced, might be worth a look.
