DenF923The deathadder has a perfect 1:1 response to user input.
This mouse has hardware acceleration in the vein of 20g, which throws off the actual input. A deathadder is better than this mouse since it has a flawless sensor, while this mouse uses a A3090 sensor, which again; has hardware acceleration, and is therefore not flawless.
Fact sheet for anyone interested in the A3090 sensor in this mouse:

Also this sensor has hardware angle snapping which is absolute mouse cancer, but that is disabled in zowie EC eVo brand mice, I don't know if it's disabled in this particular mouse since it IS an OEM.
Toxic_NinjaIf you're referring to the second paragraph of that data sheet about the 20g of acceleration that says, "The sensor is capable of sensing high speed mouse motion - up to 60 inches per second and acceleration up to 20g – for increased user precision and smoothness."
The 20g isn't hardware acceleration built into the sensor. It would mean it detects acceleration up to 20g's. Which would it probably does have a 1:1 response to user input. And why would a gaming mouse have hardware angle snapping enabled by default. I doubt it has that enabled.
