Set Timer Resolution--any potential effect on input lag?

TimerResolution is an application to change the resolution of the default windows timer. The standard timer on Windows XP can vary between 10 and 25 milliseconds. Therefore if your code uses a timer or sleep value less than the timer resolution on your system you won’t be getting the results you expect.

I'm curious what effects reducing the timer resolution could have on input lag. It reduces DPC Latency dramatically for me, but has no significant effect on FPS (according to TF2 benchmarks) that's about all I can confirm.

Default is 15.6ms or 16ms. Applications (and browsers) are changing timer. Even games. Check it: run game and check it http://technet.microsoft.com/en-us/sysi ... s/bb897568
Another easy tool to change it to minimal: https://github.com/tebjan/TimerTool
My game changing it to 1ms and can't feel difference with 0,5ms. Imho waste of time.

if your fps/frame times don't change, it shouldn't matter
