I had a very similar experience except it was on ps5 and then Pc for the MW3 beta using geo-filter with <39 Ms pings
both I felt a second behind and was very frustrated, so I decided to test out mw2 and Cold War. Both had the same results. I tried to disable QOS and PDI on the router but nothing changed, so I disabled geo-filter and the experienced changed for me instantly…..
something about the Geo-filter is causing latency!!
