Quite frankly.
Since 17.1 the game has become next to unplayable. A good way to prove that they are memory leaks is just to exit to menu after loading a map and try to get back in a different game. you'll fill 16Gb of ram almost instantly since your game don't unload the previous map data from the ram in between or something.
Beside, Every times I go in a POI and start engaging Zombs in CQC ... the screen just freezes randomly and the zomb's hit reg fails and all.
Its horrendous.
