Mouse 125Hz vs 500Hz vs 1000Hz visible when strobed or GSYNC

is usb limited to 1000hz? If not, I'd imagine that some company had already came out with 2000hz mice already

USB is not limited to 1000hz, if you're using short packets (e.g. 64 byte USB packets). You can push several tens of thousands of those per second (if you do a USB flush right after every packet) through a USB 2.0 port (you don't need USB 3.0).

The problem is the timing jitter gets so bad that timing of arrival of packets is sometimes +/- several hundred microseconds. Thanks to USB buffering and polling logic. But there are ways around this. 1000Hz is currently the practical "stable" medium. But a direct connection to a motherboard USB 2.0 or USB 3.0 port, 0combined with the right drivers (USB autoflush on PC end) and mouse end (USB autoflush on mouse end), you can get the timing jitter down to about 0.1-0.2ms, which is stable enough for a 2000Hz mouse. You want the USB "ping" to be stable, if we're going to enter the 2000Hz frontier. The barriers to 2000Hz operation is lifting, and from the visibility of 500Hz vs 1000Hz, it soon will be worthwhile to see 1000Hz vs 2000Hz before the end of this decade.

If I am only using USB 2.0 port for my mouse, should I use 500hz or 1000hz polling rate?

1000Hz is no problem even for a 5-year-old computer. It's those 10-year-old computers you gotta watch out for.
The "Cant do 1000Hz" is a silly old assumption.

The photographs are taken of my Razer DeathAdder attached to a USB 2.0 port. I should test USB 3.0 if things are even better. It may not be a perfect mouse for some competitive gamers, but for a casual gamer very picky on stutter-freeness and blurfree-ness, it is a pretty high end mouse. There may actually be more reliable 1000Hz mouse out there -- but the point of this thread was to show that 500Hz and 1000Hz actually have human-visible microstutter differences. Some people don't believe this. I say, here's photographic proof.

Thanks. I'd been using my Zowie FK at 500hz, but I will try it at 1000hz instead

There are reasons why 500Hz is better (old systems, sensor behaviour) for competitive, but not if you are using LightBoost on new systems. Once you do blur reduction, 1000Hz helps during strobing.

Hmm, well I don't use ULMB in my games much, but I have it on ULMB 120hz mode for the desktop all the time.

It's harder to see 1000Hz benefits without ULMB or other strobe tech. Do the window small-text dragging test in the first post, and see if you can see a readability difference during fast drags.

I didn't think you could hold 1000hz, even through fast USB 3.0 port...

Polling rate is independent from data transfer speed. 1000Hz in USB 2 works just the same as in USB 3. Polling rate is how many times per second you read something from USB, not how much data you read.

Haha, yeah I can definitely see it. I didn't even think I would be able to see 125hz, but it stutters like crazy

Yep. The stutters you are seeing is lower frequency than 125Hz. The harmonic frequency difference between 120Hz refresh rate and 125Hz mouse pollrate, is only 5 Hertz. It's like playing a 120Hz sound and a 125Hz sound -- you hear a 5Hz beat frequency. The mouse microstutters is the visual beat-frequency effect betwen display Hz and mouse Hz (assuming framerate in sync with refreshrate), as seen photographically.

I see. So it doesn't really matter if you're using 2.0 or 3.0?

Only reason I ask, is I have some 3.0 ports, but I use windows 7. And whilst there are drivers that support it, I heard windows 7 doesn't support usb 3.0 properly or something, so I avoid using them.
