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).
