It doesnt work, sbmm was removed because if this, you would be quick enough to moan that you are connecting to people from other continents quick enough because sbmm doesnt factor in where you are to the other players on a peer to peer server. Then it becomes a laggy mess The only thing to do is get better, i know it sounds like a bad reaponse but it is the healthiest way. Get better at positioning, understand the guns and abilities you use to utilise them most efficiently, practice more advanced movement. It is going to be tough but sbmm creates more issues than it solves. Plus stasis will get nerfed soon enough so we have that to look forward to.
