Mouse sensitivity

what parameters effect mouse sensitivity in overwatch? (other then DPI and in-game sens),because I have recently formatted my pc,and after setting my mouse DPI to 900 (which is the DPI that I had before formatting the pc) and making sure that my in game sensitivity is 6 (which is what I had),my mouse sensitivity still feels weird and diffrent.
I have a feeling that it has to do with some other setting in my mouse driver software but I’m not sure.(because after playing with those other setting in the software I have only really felt a diffrence in my mouse speed while I’m using a normal windows app,and not in the overwatch client.
I have a Maurus GX gaming mouse,and I’m using the software the was provided in the box with the mouse.
this is how the software looks like:
