3090 architecture roots from the original 2020 IC design exclusive to Logitech. Logitech had a lens developed and optimized for the 400-800 resolution count sensor developed under Agilent Technologies. That same setup has carried all the way down from MX500 to G400S.
When the IC went public under A3060 (late 04), Agilent provided their own specified and supported lens. The rest is history.
While manufacturers have the option to essentially use custom solutions, have fun trying to get the sensor manufacturer to support your product. Logitech is likely an exception for above reasoning. That and it's not like they would provide you a custom sensor design unless you happen to be a top client.
Yes, the official lens has a higher typical lift off per specific surface and LED, but imaging accuracy is at its very best. It's not like you can't experiment with other material and colors.. I personally had a red led model doing under 2.4mm on a pink/red mouse pad. 3.5mm on black QCK.
I am now on 600cpi and it does feel better, but I don't know if it's a "native" setting. Why doesn't razer just tell us all so we can stop guessing?
So what you're saying sky is that the 4g sensor doesn't have interpolation? So would the 4g be better than the 3/3.5g?
I'm saying it points to a single resolution variable (6400), but I nor anyone else here can confirm this... Unless a Razer project manager or R&D member would like to explain.
Just use what feels good.Edited by Skylit - 6/4/13 at 2:51pm
