My mouse "microstutters" @75fps while moving and aiming. HELP pls

Hi. I have a new GT72S with 980M and noticed microstuttering in games (Crysis 3, Battlefront), while they are on 75fps.

When I walk and move my mouse slightly, I feel stuttering, the camera "jumps" a very tiny bit.
I am almost sure that its my Logitech Performance MX mouse.
When I play with xbox controller its fine and very smooth, so my Notebook has enough power to handle the games.

I have newest Bios and EC firmware.
Tried different Nvidia drivers..

I am going crazy, need ur help.
You can see here, what I mean (by another user):
Look at bottom right corner to see this stuttering.

My mouse has 125hz polling rate; i play @75hz, so it should be enough.
Does anybody know this problem?

 

Are you using Logitech's drivers with your mouse? If so, have you uninstalled them and tried playing games without the software? If it then works fine, see if you can install any older or newer software and see if that helps.

 

I have no software. Its s plug-and-play USB mouse and it worked out of the box
Where can I find drivers for Win10? Couldnt find it on official logitech site.

Chose Windows 10 and the 64-bit full installer from the drop down menus.

 

Hi, i tried it, but problem remains.
I tested 3 diff. mouses (1x cable, 2x wireless)...
I think, that they are too slow with 125mhz and that I need a faster gamingmouse.

Can anybody test it? If u have a standard mouse with 125mhz polling rate and u move circles in an ego-shooter and walk the same time, is it silky-smooth oder you see microstutters, if u look very closely?

its funny, because I never noticed it, because I never was playing at 60fps. Now, that I start, I see this "lag"

 

Isn't your screens refresh rate 75hz? Sounds like it's more to do with vsync/gysnc engaging/disengaging once you hit your screen's limit.
