Weird Mouse Delay/Floatiness

[zenniscalling]

I had a Logitech G502 for a couple of months now, after I spent some cash on a new setup, (Samsung curved monitor 4ms, RX 560) I have noticed that after I play a couple matches of LoL, OW, or even Fortnite, my mouse starts to feel weird and floaty, or in better words, weirdly smooth. I bought a Logitech G703 today and still get the same issue using it wireless or wired. It would be greatly appreciated!

Both mice use exactly the same sensor, PWM3366, so should feel exactly the same.

The PWM3360 it's based on has considerable smoothing above 2000dpi so should feel floaty there. However the PWM3366 is the same sensor with firmware customized for Logitech who supposedly specified no smoothing. The PWM3389 is the same sensor customized for Razer, who ordered even more smoothing.

Smoothing interpolates raw data from the mouse and uses an algorithm to estimate probable locations for new data in between, simulating data that does not exist in order to increase perceived dpi and smooth the cursor movement on the screen. In practice it just feels weird and floaty as you describe.
