Question / Help Stream settings help

rsvpSC2 · Apr 15, 2013

Hi, I'm having a bit of trouble getting a lag-free/stable stream set up going. I'm currently using settings at much lower than the suggestions from the estimator, but I'm still getting some lag/network spikes each minute while streaming Starcraft 2.

Details from my log are below - how can I change my settings to improve the lag I'm getting? Also am I limited more so by my hardware or my network?

Is my case hopeless or something :(

dodgepong · Apr 16, 2013

Don't use Monitor capture if Aero is enabled. Either disable Aero, or use Window capture. Also, 1600x900 is too high a resolution for that bit rate...either raise your bit rate, or lower your resolution.

Have you tried the Minimize Network Impact option?

rsvpSC2 · Apr 18, 2013

How do I use window capture? My only source is using game capture. Anyway I tried disabling aero but it still didn't help. I'm already using the Minimize Network Impact option.

I also just tried downscaling the resolution by 1.5 and increasing the bit rate to 1500, but it's not any better.

Krazy · Apr 18, 2013

Your log file indicates you have a Monitor Capture source in your scene. You need to delete this.

Though, really, you aren't lagging/dropping many frames at all so I'm not really sure what the issue is here?

rsvpSC2 · Apr 18, 2013

Oh I see, the monitor capture source was unchecked but still there. My issue is that my game freezes up for about half a second every 10 seconds or so when I'm streaming. When I show FPS in game (Starcraft 2), they're recorded as "network spikes"

dodgepong · Apr 18, 2013

Maybe try enabling CBR?

rsvpSC2 · Apr 19, 2013

Enabling CBR didn't help either. Is this mostly an issue with my internet/network?

Krazy · Apr 19, 2013

Hmmm, does this happen every game you play, even during a long session?

rsvpSC2 · Apr 19, 2013

Yes this happens every single time, I've multiple times at different times. I haven't tried a long session, the longest I've done was 20-30 minutes and the problem persisted through the entire time.

Krazy · Apr 20, 2013

Ok, well I've noticed that every time I do a fresh SC2 session, I get these periodic pauses when I see a unit/building/spell in game for the first time. It's some stupid asset caching issue that has persisted on and off for a while now, and in D3 as well.

Try running the unit preloader custom map before playing or something and see if that alleviates the issue.

rsvpSC2 · Apr 20, 2013

Yea I'm aware of that issue, and preloading doesn't help at all.

Krazy · Apr 21, 2013

Hm, then I'm out of ideas...

If you are overclocking your CPU/GPU maybe try temporarily scaling those back and see if maybe it's a stability issue or something.

hilalpro · Apr 21, 2013

Run a little program called shaper probe and post the results.

rsvpSC2 · Apr 23, 2013

DiffProbe release. January 2012. Build 1008.
Shaper Detection Module.

Connected to server 38.98.51.17.

Estimating capacity:
Upstream: 4244 Kbps.
Downstream: 14500 Kbps.

The measurement will take upto 2.5 minutes. Please wait.

Checking for traffic shapers:

Upstream: Burst size: 4758-4836 KB;
Shaping rate: 2090 Kbps.

Downstream: No shaper detected.
Median received rate: 14224 Kbps.

hilalpro · Apr 23, 2013

Are you still running at 1000 bitrate like the first log is showing ? update obs and post a log if possible.

also try downscaling since that bitrate and your upload overall is not efficient for 900p try 720p30fps and keep it under 1800 bitrate

Krazy · Apr 24, 2013

Bah, I should have known. I glossed over the fact that you had Comcast. The shaper probe test is showing your real upload speed as Comcast fudges for speed test sites. On top of that, the connection itself might not be great to begin with and really struggles to have your stream + the game going without issues.

Floatingthru · Apr 24, 2013

Have you power cycled your modem in the past few weeks? If you haven't I would do it right now since Comcast has done a nation wide speed increase for anyone with performance and blast tier internet. If you had 16/2 performance you will get ~24/4 with NO powerboost so speedtests will be a little bit more accurate.
