Like many others, i have struggled quite a bit with the connection in Modern Warfare. Poor HitReg, feeling like my character was always 1 second in front of and behind what i was seeing on screen, regularly connecting to high ping servers (60-100ms) when the closest servers to me in SoCal usually net me 12-19ms. After some reading in here last night, i made a few changes that ended up drastically improving my experience with this game, virtually eliminating all of the above mentioned issues. I played with these new settings for over 2 hours and the results remained consistent. 90% of that gameplay was spent in League play where i really notice my connection. What i did? Disabled QoS features. I run my Geo-Filtering at [2000km, Strict Mode, Ping Assist @35]
Previously, i had the bufferbloat disabled, but was running Bandwidth Allocation settings (Giving my Xbox 60% Down/Up) and Traffic Prioritization w/ DumaOS Classified Games. Attached is a picture of the ports i have forwarded.
Modem: Motorola MB8600
Router: Netduma R1
ISP: Cox Fiber 1000 down/35 up
Console: Xbox OneX w/ a wired connection
Monitor: BenQ XL2411 24” <1ms
I don’t know if this will be a fix for all of you, but I hope it helps. Please feel free to ask any specific questions you might have and i will do my best to answer them. I’m still fairly new to a lot of these settings and what they actually do.
