The player with the ADF-10 is clearly really good, the fact that he use the gun, suggests that is using the upgrades to the damage of the gun, giving him the upper hand in close range, if you notice when you psm, the missiles take a weird angle when fired, so that because you don't hit him, but I actually don't know how to "help" you, I mean, I play MP like I play the campagn, maybe use a more manuvarable aircraft in may experience the X-02S is the best, (the railgun is fun to use), if not I suggests you the Su-37, the skill base in this game is large sometimes you win sometimes you lose in my experience, last thing can I ask you which upgrades you are using on the Su 57? Maybe try upgrades the missile homing level 2 and there is also one of the light blue upgrades that improve standard missiles in general.
