I've tried something today different on PS5 after reading another post I firstly (1)disabled Network Priorties in netduma r2 (2) then change MTU to 1472 PS5 (3) Then circled UK map 0 ping assist and strict mode...... And I was amazed how MW2 played for the first time in along time I was getting the upper hand in most games, hit marker were bang on and plenty of killstreaks up....Still had the odd game where my shots weren't registering at there best but I found myself staying in games to the end without shouting at the TV to much and leaving games. 😘
