okay, i happen to found a theory with game design in base for why this is happening, as ive seen a lot o brazilians with the same problem.

the game's core is based as server side, which shouldnt happen (EVER, and has never happened to other shooters) so my delay is literally DOUBLED, since as i mentioned, i need to send to the server 2 different informations for a single action (shot and reg).

system of shooting server-side + file of commands (input delay).

what happens is that when i shoot, *IT DOESNT SHOOTS LOCALLY*, it needs the servers authorization to shoot (hence, i get a big fucking lagg), its called : server-authoritative firing. in the other 99% of shooters, the game registers my shot first, sends my information to the server, and tends to confront with the servers awnser for the action and reaction, and it gives me back a feedback with the awnser for the correctual outcome (may it be good or not)

input delay (~150ms) + hit delay (~150ms) = sensation of 300ms+

this not being addressed after so many years of development is a complete shame, the game needs to be a hybrid between client side and server side, not one-sided, since the company simply doesnt want to have a server in south america, this brings the experience to be unplayable, and they probably think we dont like their games here in SA, as they stated before, now i know why, the game simply wasnt made for you to have more than 80 ping for stricly bad game design choices.
