Mouse Laggy Movements,

And before you start complaining about ''oh there's already a fix for this'' No,i already tried that and it has nothing to do with my sensitivity.this happened when i was in the middle of a match,my mouse started lagging. When ever i move it,its sketchy looking i guess not smooth and up to date,it has nothing to do with my computer. it has everything to do with crossfire being a ****ty made game,excuse my language but it's true. no other games do i have this problem with,but crossfire. and yet i spend money on crossfire,for what? in game items,and to pay for there server fees/support fees yet they don't fix stupid bugs like this,nor pay for a higher anti hacking system,they're tons better than ''xtrap'' and it's just ridiculous on the amount of hackers,to the extent of aim botting/speed hacking etc etc. just,what the hell can i do that will actually fix my laggy mouse issues with crossfire,it is not my mouse because i have tried using two others,this has happened before (but in a worse case) and it fixed on the new patch (last patch)...Thank you one thousand times if you actually know what you're doing/saying to help me fix this problem.
