neat, 100ms is blatantly obvious, I can't imagine anyone not discerning that one.
I can get down to 24ms but no less... the weird thing is that 24ms is still completely obvious to me (clearly shorter but obvious in comparison to no delay), with a single test I can see which variable has the delay every time, but 1ms less and I can't... which makes me suspect it's being quantised due to any of the various things in between sleep and the output, display, driver, X, terminal emulator, CPU etc.
With that it's actually possible that my 24ms is larger than 24ms and is also being quantised to a larger duration (but not larger than 100 for sure).
It would be interesting to be able to test with some dedicated hardware.
Your probably right, it's an old TN panel in a 10yr old laptop... I'm gona have to steal someones shiny modern IPS in a minute :P (I know they are generally slower response but it's 10 years newer so you never know)
[edit]
No IPS still super slow. How common are >60Hz computer displays these days?
