If you have a good cirriculum-vitae of past experiences doing this stuff, you can contact Razer_TheFriend on Twitter. He's sending 'em out to select researchers and game developers, in exchange for good hard data. It's a big goal of getting industry ready.
Good suggestion, however...
I'm doing it in HTML5 using PointerEvents + PointerLock. Thanks to the way Chrome does Stadia, HTML5 in some brands of browsers can now do data as accurately as MouseTester now (1000Hz+rawinput). Far easier and fancier graphs than MouseTester. Mind you, there's bugs being able to run 8000Hz, but it's perfectly fine at 1000Hz. Eventually I'll coordinate Razer+Chrome team to fix the 8000Hz Chromium bugs, as I've long trailblazed the W3C stuff to make their browsers more and more TestUFO compatible; sending lots of BugZillas and CRbugs, that fixed issues.
BTW, this is a good time for me to go on a (temporary) topic sidetrack to explain why I am doing it in sometimes-imprecise HTML5 and not precision C++. (That said, browsers are getting amazing in some departments thanks to other influences such as Google improving compatibility with 1000Hz gaming mice in Chrome due to Stadia).
You have to realize how Blur Busters work. I'm the one who invented high-Hz-compatible "one click show-and-tell motion demos". I'm doing the same for mouse tests. My goals are different. I'll sacrifice a little bit of C++ precision to have one click convenience to massmarket. 1000-times more popular is more valuable to Blur Busters Prime Directive.
Blur Busters is a hobby-turned-startup with two lines of businesses
Blur Busters is a two-lines-of-business hobby-turned-startup. Blur Busters Media goals (advanced-mainstream microphone dropping factory) is different from the Blur Busters Laboratory (working with manufacturers). I newbie-ify my language in the Blur Busters Media department. I still write too advanced, but it's branching out over the years. Everyone tends to respect that, and sometimes it means I write Popular Science Articles instead of Harvard University Thesis. Other researchers can cherrypick my Hertz Einstein ideas and write their own Thesises or Papers like more than 20+ different groups of researchers wrote peer reviewed papers crediting me or my business (most recently, Samsung researchers in September, about a new motion blur measurement standard).
Buddy, TestUFO has almost a hundred million lifetime visits worldwide from 2012-2020, being the world's most popular one-click motion demo to silence a lot of myths (descendants of "Humans Can't See 30fps Versus 60fps"). I'm going to bring that to mouse testing. And y'know, in my bandwidth traffic, Asia region has an unusual workday traffic pattern on TestUFO. China/Taiwan/HongKong/Korea/Japan has a strong cyclic traffic indicative of many hundreds/thousands companies using my TestUFO as part of their work, a cyclic pattern found nowhere else (no other country). It's so strong that when worldwide bandwidth is averaged, the weekday workday cyclics contributed by Asia still shows up clearly in the worldwide bandwidth average.
Blur Busters is happy working in this manner; we don't give fish; we teach people to fish. That's why Blur Busters does not mass-test monitors (except Special Editions), but dozens of others use Blur Busters inventions to mass-test monitors. I don't compete against the people who use my inventions. I've taught a lot of people to fish. I dislike it when people criticize how Blur Busters functions (sorry) when people demand I mass-test monitors or do something else more researcher/scientist-appropriate. Yes, I long wish to be a YouTuber, but being a deafie -- born deaf but with a brain able to emulate a motion test (like a motion-photogenic logic in my brain, mentally looking at the rainbow artifacts, plasma contouring artifacts, GtG artifacts, persistence artifacts, optical illusions, etc) before writing the motion test -- I find it much easier to blog and show-n-tell via other means. Instead, I rather incubate the path, and any demands & disrespect will just be unceremoniously deleted. If you want to create a C++ MouseTester, be my guest. That is not the Blur Busters mission directive to give away fish. Whether it's ApertureGrille or RTINGS or TFTCentral or LinusTechTips or multiple monitor manufacturers, they're deriving a lot of their tests based off what Blur Busters freely inspired them.
Even many startups have been inspired by Blur Busters (Even practical nausea-free VR arrived a few years earlier than expected thanks to TestUFO, from a paid contract between myself and the Oculus Kickstarter completed long before the Facebook days). Zero Oculus or Facebook stock/options ever. Don't mind. If that means I leave lots of money on the table, nearly everybody respects that, and most businesses approaching me at the beginning knows to respect that too. Ever my lawyer remarked that it's pretty clear that it's something commendable and respectworthy, even though it is metaphorically tantamount to a cultural difference between businesses in different countries. (Yeah, I've already had to defend my way of business function. Fortunately, it's nothing involving any big companies -- they are so experienced and know people like me and work with many people like me already, and they love working with me). Whether it's about a mouse, or a 240Hz strobe backlight, or a quadruple-digit refresh rate prototype, or troubleshooting why their shutter glasses doesn't work well on a specific display, or creating a custom TestUFO for their in-house use, or teaching a class at a manufacturer across the Pacific or Atlantic, or other meritworthy contribution to the refresh rate race to retina refresh rates.
P.S. Somebody else? Sure. Please write a C++ opensource version of MouseTester and put it on github. Perhaps I'll contribute GitHub / BugZilla Issue reports, and maybe a couple of source code commits.
P.P.S. My Special Edition article (at least Part #1) is focussed on mainstream photographic-proof microphone dropping to stop the 8000Hz-laughing audience before next steps -- before more scientific results in Part #2 onwards. The Blur Busters Way is our forumula. Thus, there is little MouseTester-style results in Part #1; just to temper expectations.
