Well for me 10Hz tickrate is kind of good in Battlefield 3 since DICE don't wanna to overload the CPU bandwidth and they rise it up to 30Hz in the new netcode fix of BF4 yet that will push your CPU further
I may sometime find some netcode issue in BF3 (TV missle / tank hit but 0 damage ) I think rising ot 15 / 30 will be awesome but as the Green guy said it's kind of tricky to do
