How to lower the .1% Frametime?

[The_Nephilim]

Hey Guys,

I recently seen in fpsVR I can see my 1% and .1% FRametimes. I had noticed the .1% was rather high and I am trying to reduce it under 16.6ms. I am currently around 17.6ms so I am close, I was just wondering if this is even possible to do?

Having lowered it from about 26.5ms I am close now but it still has eluded me.. I am wondering since DCS Seems to always have that random spike if it would even be possible in DCS to lower the .1% FT down under 16.6ms?

 

I was wondering what setting would affect that FT the most if anybody knows? I have lowered the main FT too 6.7ms but the .1% seems problematic.. I was going to try and reduce the resolution in the VR Headset and see what happens I was just looking for some suggestions on what else I could try here?  thank you.

disable the power service (and every other background process you can live without).

The .1 lows are mostly caused by interrupt calls from other processes.

The power service is one of the big offenders and easy to live without with.

I suppose you have disabled the AV already.

Attach your DCS log file in case it highlights any issues. I'd also recommend using https://github.com/fredemmott/XRFrameTools vs. fpsVR to test this out. You can export the results to a CSV file and then for the frame timings it will show other things happening at the same time which may identify the cause of the increase in those.

yes I had AV disabled when running but not when testing will do that as well. and here is my DCS Log and I will try to run that program you suggested sleighzy..

I had exported the log file as a csv file and I needed office to open it up, is this the correct way and here is he file incase anybody wanted to have a look as I know nothing here??
