Re: Why the heck I can't tell a difference between ULMB2 on vs off at 540Hz ???

Im sorry its still looks the same LOL

I am so confused, when I turn on ULMB2, I can adjust pulse width and what not, and if I adjust it, the brightness goes down, so obviously its doing something but idk its just not working :(((

You can always do a handwave pursuit camera for demonstration.

I gotta try dyac+ next time inshallah

You need to test really fast motionspeeds, more than 2x, preferably3x-6x faster in pps than (1/MPRT) in number to easily tell the difference.

- Try 2000-3000 pixels/sec for 540Hz.
- That way you have 4 to 6 pixelstep per frame (stationary gaze) or 4 to 6 pixels of motionblur per frame (tracking gaze)
- And you will be able to see pulsewidth changes.

For 2ms MPRT, you need 1000+ pixels/sec to see differences
For 1ms MPRT, you need 2000+ pixels/sec to see differences
For 0.5ms MPRT, you need 4000+ pixels/sec to see differences
MPRT is frametime on unstrobed (assuming GtG=0)
MPRT is pulsewidth on strobed

Also, your mouse now becomes a severe weak link at these stratospheres ("I can't tell" = sometimes mouse's fault).

Please fix your in-game mouselooks to be TestUFO-smooth:

1. Please fix your mouse microstutters.
2. Upgrade your mouse to a good sensor that does a good job of >1000Hz >1000dpi.
3. Try ~2000Hz + ~3200dpi
(2000Hz gets 90% of benefits of 8000Hz while spending 75% less CPU in mouse event code. Not all games work well at 8000Hz)
4. You can balance in-game sensitivity downwards using sensitivity calculators like www.mouse-sensitivity.com to preserve muscle memory at 2000Hz + 3200dpi.
5. Please use clean mouse pad and clean mouse feet
6. Turn off "Enhance Pointer Precision" in Control Panel, that distorts cursor speeds everytime you switch pollrate / switch DPI

As long as you're not using old engines like CS:GO or World of Warcraft, many paid esports players are now transitioning to >1000dpi nowadays, leaving behind legacy 400dpi or 800dpi (except for tricks like snap-to-horizontal from low dpi granularity... but today's kids are gaining new superpowers from more reliable high-DPI which you now need to compete with).

You gain the superpower of slow mouselooks becoming TestUFO-smooth. Great for aiming moving objects like flying airplanes, vehicles, or objects that move approximately as fast as TestUFO motions (Etc).

The issue at 2000-3000 pixels/sec it kind of becomes so fast I start to kind of get dizzy and its hard to read that fast, is that normal, are you guys able to read the text on that UFO test using that speed?

This is definitely something I will be trying next, as I was testing using 1000Hz polling rate as I was waiting for my hyperpoling razer dongle to arrive and it finally did. Just waiting for my mousepad and will give it another shot, otherwise, its either something faulty with monitor or strobing at those Hz is kind of pointless since its already pretty clear OR I gotta try dyac+

At 1080p, it's too fast.

But at 4K, it's much slower (half the speed for same screen size, due to twice dpi).

That's why higher resolutions amplify MPRT visibility / refresh rate differences. (1440p, and 4K)
