i'm not an expert in networking in general 
, what i'm trying to do is improving gaming connection with configuration i notice when i started igmpproxy the game animation
felt slightly smoother i don't know why but it does , i believe it's a matter of configuration and there is more thing can be done other then bufferbloat and qos in general and lowering ping
any help would appreciated.
i able to get A+ on bufferbloat with sqm 80% of my actual speed and with nft-qos 80% of sqm speed
that also what i found
