I have a 360 Hz monitor and my average framerate bounces around that amount (I keep it uncapped.) What polling rate should I have my mouse at? I use a DeathAdder V3 Wired that goes up to 8000 hz.
Can add extra info as needed.
I'd suggest watching this video and coming to your own conclusion (Pretty much higher polling rate -> Lower Battery life, also polling rate is like refresh rate: there's diminishing returns with higher values)
