I've got an XR500 and have used it to try and get lower ping on COD/ Warzone for a few months. For some reason, I'm still getting 'rubber-banding' and the occasional packet loss, as well feeling like my hit detrection is off. I've run numerous connection benchmark tests on my LAN and Wi-Fi 70down and 20up and get A+ for everything bar under load where my upload ping goes way over 200ms. I've got my QOS currently at 70/70 and I've scoured these forums to find a solution and tried virtually every possible solution. Just for reference, my setup is from the ONT to EE router, which then is wired into the XR500 that I've connected to both via wi-fi and LAN with no major difference between them. I've used a few traffic prioritization rules, which I'll post below, as well as other screenshots too. Any help is appreciated.
EDIT: The PS5 and my laptop are the only active connections to the XR500, my laptop when I'm playing only had the Duma os running.
