I just got the 1080ti FTW3, and when I'm using Precision XOC, I experience significant input delay with my keyboard, to the point that it makes games pretty unplayable.  This is with/without any sort of overlays.  I tried to use Afterburner instead, but it seems that Afterburner will only control a single fan.  I tried to use neither, but my fans wouldn't ramp up and my card started to overheat.
 
What's the deal with XOC, and what are my other options if I can't use Afterburner?

Sorry for the lack of details, it was late and I was a little frustrated.
 
My system specs:
 
GTX 1080ti FTW3
6700K
32GB ram
Windows Home 64
 
I tried closing every non-essential program so that there were no conflicts which didn't fix it.  I tried installing 6.1.4 which didn't fix it.  Then, I went into the OSD settings and manually disabled all of the hardware monitoring, which seems to have fixed the problem.  Apparently I can re-enable the monitoring, just so long as I have the hardware monitor window closed, and the problem goes away.
 
It's hard for me to believe that an issue like having the hardware monitor open would cause significant input lag, as this is one of the main draws of having monitoring software.  Is this an issue for everyone?  And why hasn't something like this been addressed yet?  I'd like to use Afterburner so that I can monitor my system while I'm playing, but apparently that can't work with iCX.

Yes, Hardware Monitor causing input lag has been an issue for some people and is nothing new, hence the first thing on my 'list of things to try'..At least you know exactly what the problem was now.
