I own three Avago 3090 mice:
- Roccat Savu (4000 DPI firmware)
- Kana V2 (4000 DPI firmware)
- G400 (3500 DPI firmware)
I use 800 DPI / 1000hz on all three mice with no software installed. The Savu and Kana v2 both feel very similar, and also worse compared to the G400 with same settings.
The cursor feels like it's connected directly to my hand on the 3500 DPI G400, while it's a smoothing/lag fest with the other two mice.
The 3500 DPI 3.5g Abyssus feels much closer to the 3500 DPI G400 than the Savu or Kana v2 as well.
The 4000 DPI Avago 3090 firmware is VASTLY inferior to the 3500 DPI one and completely unusable to me.
