BUG SOLVED
THANKS TO SysOpPsyche
Solving process:
If you're having this bug, that means you're using a high performance mouse, which has at least a 500Hz polling rate (in my case was 1000, which is worse). Enter your mouse software, and look for the options to change the polling rate. In case is a razer, it will be "Tweak performance->polling rate" and lower it to 125 Hz.
You just turned your turbopro1337gamingmouse into a crappy one. BUT IT WORKS.
Again, I can stretch enough how grateful I am, and the rest of the people with the problem will be, now that we can actually play and enjoy the game. I can't help having a bit of a sour impression for the fact that it wasn't reverie studios the ones who gave a **** about it, but I'm very happy that it was solved in the end.
Thanks again, see you on the battlefield
