Plutonium

I've read that the fix to this is lowering the polling rate to 125. But is there any other fix available that doesn't require me to do this?

I wanted to ask wether or not you can get T6 to somehow count your BO2 playtime on steam, since afterall i am able to shift+tab and see that steam IS infact recording my current playtime, but it never actually adds that playtime to "BO2 Multiplayer". I would appreciate any help regarding this.

when it comes to sensitivity i just typed /sensitivity 1.7, and the "double switch" command switches your weapon twice, the command is /bind mouse5 "weapnext; wait2; weapnext" that allows me to switch my gun twice, which i can use for faster reloads, its not that noticable on MW2 and BO2 but im used to it from cod4 so i put it on every older cod game

I just got on BO2 for the first time, so i tried to change my fov to 90, i typed "cg_fov 90" into the console and it changed my FOV for a single life, after i died it returned back to 65, the sensitivity command doesnt work 1 bit, and neither does the command for double switch, can anybody help me with this? how can i get the console commands to work properly?
