Mouse Movement Problem - Logitech G300s

[Malcolm-X]

Hello friends.

I use logitech g300s mouse with 600 dpi and 1.85 sensitivity in game, raw input on, no mouse acceleration in game, in mouse driver, and in windows settings. 500 rps (report per second) in the mouse driver application (tried 1000 as well). Also a very nice fiber mousepad.

It works alright when im on the desktop, or in any other game I play.

But when I launch CS Go, my mouse moves like acceleration open to the max level and it is not continuous movement, feeling like old, ball-bottomed mouses.

When I change video options, it gets even worse. I have NVidia Gforce GTX 960m on my Lenovo Y50-70 Touch laptop with 16gb memory.

I checked in game video settings, control settings etc but couldnt fix it anyway.

Any idea?
