Re: Mouse sensitivity fluctuating

what does that do?

try setting polling rate down to 125hz on keyboard and mouse.. if that helps you can go steps above

well i tried one match and the issue is gone! how and why?

Go in windows mouse settings and check if "Enable pointer precision"is unchecked.. Also try another mouse pad

"enhanced pointer precision" has always been off, i double checked. and i tried different mouse pad and with non. not positive effect.

It might be some sort of input lag.. Some that i've read causing this could be :
v-sync enabled, high polling rate (causing load on cpu), try in nvidia control panel or amd graphics app and set maximum prerendered frames lower

You can also try plugging the mouse into a seperate usb port

There are three layers or more to configuring:
Apex
Custom Mouse application
Windows mouse settings

If they are not set properly could be causing some issue softwarewise

Try monitoring cpu usage and find if there is a correlation between high cpu load and mouse changing its sensitivity

i checked everything you mentioned. put my nvidia option you said to 1.
it seems fluid now, but i noticed when i got into firefight a few times it did kind of slow down as if a tiny mouse turned my DPI down to 500 and then back to 2k+ etc.

this did start happening after the update, i feel like this is apex network related, i don't have this issue with other games.

Most gaming mouses these days have DPI buttons.. I have a steelseries mouse it's located right behind the scroll button where i accidently pressed it in game by scrolling inventory.. I would suggest if u have that type of button to remap it using the custom software
