I have the new Razer 8000 Hz prototype gaming mouse on my desk.

Problem: High-Hz poll performance interference between 1000 Hz keyboard + 1000 Hz mouse

While I'm pretty convinced that 8k hz mouse polling is going to be not only noticeable but also impactful , I'm starting to wonder how much keyboard polling will affect this. High keyboard polling has known to destabilize the mouse polling and vice versa.

Image
For example this is a 1khz mouse polling on an optimized setup with a 125hz keyboard. As you can see the variance is quite little, barely 1hz.

Image
This is the same mouse but the keyboard is wooting one set to 1k hz. All of a sudden the variance is 20hz. Looks like windows can't even fully handle 1k hz keyboard and mouse at the same time.

With keyboards now supporting 4k hz polling like the Corsair K100, I'm curious how will this affect the stability of 8k hz mouse polling. Seeing that a 1k hz keyboard is enough to destabilize a mouse set to just 1k hz, a 4k hz keyboard would probably trash the stability of a 8k hz mouse.
Solution: Serparate USB controllers and PCI bus lanes per 1 high-pollrate device

Small update, using the asmedia port for keyboard (the lowest one, right next to the usb-c port) while using top port for mouse seems to minimize if not remove the impact of high keyboard polling on the mouse polls.

Image

Blue is the mouse and red is the keyboard. This combo provided the best polling, pic of polling attached below.

Yeah, that was what I thought. Glad my recommendation helped!

With ultrahigh poll rates, you really need to isolate to one USB chip (and/or separate bus lanes) per high-pollrate device.

PCI-Express USB cards are also another solution that can help this. Plug the keyboard into the motherboard USB, and plug the mouse into the PCI-Express USB. Or do do USB port roulette until you find jackpot.

This would probably become a staple recommendation of the new 2020s-era "Blur Busters Mouse Guide II"

Until the motherboard manufacturers "keeps up with the Joneses" and have a dedicated-USB-chip keyboard port, and a dedicated-USB-chip mouse port for the 2020-2030s esports era of 4000 Hz keyboard + 8000 Hz mouse + >360 Hz monitors + RTX 3080+ framerates.

This Grand gaming computer upgrade supercycle is going to be very interesting. I rarely see so many concurrent upgrades happen. Those now seem to happen only once every 5-10 years, rather than every 2-3 years in the 1990s-2000s. We are seeing a major Vicious Cycle Effect tick-tock (multiple concurrent frequency upgrades).

Or do do USB port roulette until you find jackpot. Keep the adjacent ports empty (port above/below a plugged-in high-Hz USB device) because they often share the same USB controller.
This could explain why using Gigabyte's DAC-UP 2 USB 2.0 to plug the mouse on my motherboard felt more consistent than USB 3.0 and 3.1 Gen 2 ports, it was using an isolated power source to minimize noise and it was using it's own usb controller, it was technically aimed for noise free DAC connections as an alternative to optical.

I should try to MouseTest this port just to be 100% sure.

It would be awesome if there was a mouse tester web page like the test ufo pages. If that is possible to do in a web browser.
You could have a whole suite of tests people can do to quickly get their pc tweaked for peak performance.

Yes, I have a TestUFO mouse tester coming. Basically an online verison of MouseTester.exe

(HTML5 is now complete enough to do 1000Hz+rawinput)

I can't wait to try it! When are you planning to release it?

so this applies to 1khz 1khz setting now too I assume?

Nominally at the end of the month, but Blur Busters is famous for working on Valve Time for some projects -- but it'll be definitely available this year.

It'll use the same graphing engine I wrote for www.testufo.com/animation-time-graph with color coded visualizations depending on how far the poll deviates from baseline. One browser click away from a fancier MouseTester that's run online.

Chrome and Microsoft Edge (Chromium powered), running in full screen mode, are generally the best for latency.

However, nearly all TestUFO tests are latency-independent, focussing on motion testing.

resident 70/78 custom vers user. wait so you mean if I live next to Canada servers (assuming) then it's more accurate?
