Isn't USB 2.0 limited to 1000 hz polling?

Nope; 2.0 supports microframe polling as per Hi-Speed USB standard. But as of now this is exclusively for 3.0 controllers in Windows 8/10 because SweetLow figured something out in the drivers that come with that.

WMO can into 4000Hz!

does the 'perfect control' increase from 1.5m/s?

no, stays the same from 250+

actually i got it to 8000 too.

By the way, guys. Don't forget than 500Hz is the best of the best in terms of stability. So before making 2000 (or even 1000Hz) a standard we need to get rid of all this tracking issues, they're causing.

Well, that depends on a few factors, factors which most people usually just ignore.

2000 are so great with a crt but asus gladius have a shit sensor
with shit button latency

Was just about to ask if they've tried this very mouse =)

Can you elaborate on the issues you mentioned? I couldn't find button latency measurements for it and ppl say contradictory things about tracking on multicolored surfaces.

no answers for my questions there

Cool. Though it's only a difference of 0.5 ms. And microstutters occur regardless of polling rate. Looks like a 3rd factor could be the culprit. Refresh rate improvements would be much more remarkable.

1000 Hz monitors pls

>1000 Hz monitors pls
Yeah. It's better than all this blur reductions and j-syncs.
But wait.. more Hz not always better: http://www.tftcentral.co.uk/reviews/acer_predator_z35.htm
It can into 200Hz but there are no advantage between 120 and 200 on this monitor because of poor response time.
So we need 1000Hz with extra fast response time.

someone successful change logitech mouse for 2000 or more ?

Nah, those are apparently internally set to 1ms integers.

CPU usage of 1000hz is pretty high even on a top end i7 @ 4.4ghz, I can't imagine 2000hz being a good thing (although the high CPU usage is no issue with old games like Quake I'll give you that).

Quake is cpu heavy game tho

Is it? 1000Hz doesn't even register in usage on my CPU and it's pretty old.

Well if I look at process explorer/process hacker and move my mouse all over the place I can see the "interrupts" CPU usage rising quite a bit. In a recent, demanding game you can get some fps drops when turning that you don't get at 125hz.

It raises cause you highlight a fuckton of icons and windows moving it all around

lol there's barely any CPU usage difference

Actually you may be right. I remember playing around with the windows timer resolution and the difference between 1ms and 0.5ms was not even 1%.
