Question / Help OBS Stuttering When Streaming PC Play But Not Xbox Play

[Mednar]

Hi I have a problem with OBS where when streaming PC play (Overwatch) the stream stutters constantly but when streaming XBox play it performs fine. This leads me to believe it's due to pc resources but this shouldn't be the case given what I'm working with, and the performance specs I'm seeing.

I can play Overwatch on Ultra with over 120 fps without streaming. I've even tried low graphics and lowering my webcam to 420p from 1080p and my stream still stutters. I stream to both Twitch and Youtube using restream.io, but the problem isn't with that service as I can see it stuttering within OBS before it's even broadcast, and as I said, it streams XBox fine.

What I'm working with:
225mbps down/ 12mbps up
Computer:
- NZXT H440 Mid Tower Case (White)
- Intel Core i7-6700K Skylake Processor 4.0GHz
- ASUS Z170-A ATX DDR4 Motherboard
- CORSAIR DOMINATOR Platinum 32GB (2x16GB) DDR4 3200 RAM
- NVIDIA GeForce GTX 1070

What I use:
StreamLabs/TwitchAlerts Strexm Overlay ElgatoHD60 for Xbox, main monitor capture for PC Yeti mic Logitech 1080 webcam
The following OBS Settings:

I've monitored using PerfMonitor2 and EVGA PrecisionX OC and haven't seen the temps get too high or the pc load top 75% really. Any help would greatly be appreciated because despite building this beast of a PC I'm relegated to only streaming xbox until I can get this figured out.

Ignore how boring it is, will work on that once I've figured this out ;)

you need to cap your framerate to 60. Since overwatch is using all of your GPU there is not enough left to encode with. If you cap your framerate that will free up some GPU to do the encoding with.

You think it's as simple as that? Do you think the 1070 would be able to handle high graphics with a fps cap and still be able to encode for OBS? Did you find this in the logs somewhere (I'm fully unfamiliar with the logs) or is it just a hunch?

Do others agree with this? I'll test tonight and report back.

your pc log was incomplete. for some reason it doesn't have the recording end. it does have the recording start. So you might need to upload another log with a new recording in it Ill have another look.

Many people have had this issue, including me.
