Question / Help random stutter / in game lag when streaming csgo

[pmarrison]

hi there,

im having a slight problem whilst streaming csgo at 720p 60fps.

whilst moving around i get a very slight random stutter which is really distracting.
the random lag spike is still there when streaming at 30fps.

It seems isolated to the source engine and my stream on twitch seems ok with no significant lag. i would really like to fix it as i think i may have configuration problem in obs or elsewhere on my computer.
i also have a problem where if i have a flash video playing in chrome it will cause stuttering in game. I also get random lag spikes when recording video in fraps and playing back video in vlc.

Things i have tried:
- reduced cpu encoding to ultrafast
- obs preview disabled and minimized in background
- updated adobe flash
- unchecked hardware acceleration in flash player
- disabling page file
- verifying game cache
- updated ethernet drivers
- removed overclocks on both gpu and cpu
- intel qsv (problem still occurs)
- custom x264 parameters (opencl)
- reduced in game graphic settings
- capped fps_max to 67 and 128 in game)
- cpu cores are unparked
-removed monitor capture from scene
- aero enabled/disabled

Also to note: my cpu and gpu isnt throttling, my i7 barely goes above %50 whislty streaming and csgo

If somebody could help me resolve this your help would be greatly appreciated.

My specs are.

Re: random stutter when streaming csgo

well dont use the fast preset then? theres a warning message for a reason.

also that buffer size... and bitrate holy moly

twitch doesnt like bitrates over 3500 especially for non partnered streamers also the load you put on the viewers end is pretty heavy since the servers cant really keep up anyway

slightly irrelevant reply but thanks anyway.

as i mentioned above, i still get the in game stutter when using the ultrafast preset. As you can see from my specs my system will handle veryfast - fast just fine and it does so perfectly on other games including bf4.

The issue i have is not stream lag, its in game random lag spiking on csgo even with ultrafast encoding .

The bitrate in my log was just an experiment but seemed to work fine. I normally use 3500kbs with custom buffer unchecked. will edit that in log now

When you say in-game lag, are you talking about FPS drop or high ping?

hi,

its an fps drop in game. i am still getting around 120-170 fps whilst streaming the stutter occurs randomly when the fps drops by about 10-20fps.

ive tried capping my framerate in csgo but to no avail. v-sync is a big no no because of the input lag.

any suggestions?
