Re: flood's input lag measurements

Any ETA on when you'll continue your tests? Would like to see some csgo on linux vs windows tests. Keep up the good work!

I'd suggest someone that currently does latency testing via high speed camera.flood wrote:idk honestly...
i don't have the time or interest that i used to
i'm still offering to give the rig away to anyone who wants(assuming that it still works)
Pls do test 60Hz NVCP Vsync ON + maxprerendered 1 vs 60Hz NVCP Vsync ON + RTSS at 60 (or other frame limiter) aswell.Chief Blur Buster wrote:Blur Busters will be doing far more input lag related topics in the coming months. We're currently in a preparatory stage. "Keep tuned".

There are advantages and disadvantages, A high speed camera lets you see the pixel transitions and verify the accuracy of a photodiode setup(how long does it take between the monitor starting to transition and the diode triggering?) The microcontroller + photodiode setup makes it possible to isolate USB polling and eliminate debounce latency, makes gathering large amounts of data practical, and it is a whole lot cheaper than a high speed camera fast enough to get the same timing precision.Chief Blur Buster wrote:A high speed camera can be just as accurate as a photodiode
That's all true of course, with goals of isolating certain parts of the chain.Sparky wrote:There are advantages and disadvantages, A high speed camera lets you see the pixel transitions and verify the accuracy of a photodiode setup(how long does it take between the monitor starting to transition and the diode triggering?)

The microcontroller setup is also way less tedious. Getting a couple thousand data points is a matter of letting your monitor try to give your chair a seizure while you go grab a snack, and coming back 10 minutes later to save the csv.
I'm not actively working on it at the moment, but I did write up my latency tester and post the code a while ago: http://forums.blurbusters.com/viewtopic ... =50#p22634Chief Blur Buster wrote: [That said, if you're already working on lag testing techniques, please contact me mark[at]blurbusters.com ...]
